De Silva NAL, Marsden ID, Gaw S, Glover CN. Assessment of Amphibola crenata as a bioindicator of estuarine trace element pollution using biochemical and physiological endpoints. MARINE POLLUTION BULLETIN 2024; 206:116693. [PMID: 38986396 DOI: 10.1016/j.marpolbul.2024.116693] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/14/2023] [Revised: 07/02/2024] [Accepted: 07/03/2024] [Indexed: 07/12/2024]
Abstract
To assess its utility as a bioindicator of estuarine contamination, Amphibola crenata, a pulmonate mud snail, was collected from 17 estuaries in New Zealand. Whole-body soft tissue trace element concentrations were measured via quadrupole inductively coupled plasma mass spectrophotometer (Q-ICP-MS) and were found to be significantly positively correlated with sediment trace element profiles for arsenic, copper and lead. Snails from polluted estuaries generally displayed higher ammonia excretion rates, elevated whole-body soft tissue catalase activity and lipid peroxidation compared to snails from reference sites. Across all sites haemolymph glucose was positively correlated with the tissue burdens of arsenic, copper, nickel and zinc, while haemolymph protein was negatively correlated with arsenic, cadmium and zinc soft tissue concentrations, indicative of altered energy metabolism associated with trace element contamination. Overall, sites were distinguishable by application of the array of measures employed. Our findings suggest that gastropods have significant value as bioindicators of estuarine health.

Inflammation and apoptosis pathways mediated the stress response of Litopenaeus vannamei to acute cold and air exposure during waterless live transportation: Based on ultrastructure and transcriptome. FISH & SHELLFISH IMMUNOLOGY 2022; 131:391-400.

Abstract
the combination of acute cold (AC) and waterless duration (WD) constitutes the major environmental stress and induces the damage or even mortality to shrimp L. vannamei during live transport, whereas the responding mechanism to AC + WD at molecular level remains unknown. The present study aims to clarify the responding mechanism of L. vannamei to AC + WD stress by ultrastructural observation and transcriptomic analysis on hepatopancreas tissue. The results showed that the dramatical oxidative stress induced by AC + WD significantly mediated the alteration of amino acids and energy metabolism. Furthermore, KEGG pathway enrichment analysis revealed that the genes including DDO, GOT1, IDH1 and BBOX1 involved in energy metabolism and were significantly down-regulated, while some apoptosis- and inflammation-related genes such as DRONC, AP-1, and COX-2 were significantly up-regulated under AC + WD stress in comparison with those at normal control (all p < 0.05 or 0.01). These findings suggested that metabolic processes mediate the stress-induced damages of L. vannamei during waterless transport. Moreover, the significant overexpression of apoptosis-and inflammation-related proteins, and levels of inflammation cytokines in serum of shrimps strongly demonstrated the implication of inflammation and apoptosis pathways in stress-induced ultrastructural damage. These findings deepen our understanding into the response mechanisms of L. vannamei to AC + WD stress and provide the potential controlling biomarkers for transportation management.

Abstract
The impacts of cold stress (4 ℃ for 0 h, 12 h, 24 h, 36 h and 48 h, respectively) on the components, structural and physical properties of myofibrillar protein (MP) gel from Procambarus clarkii were investigated. The physicochemical analysis indicated the secondary and tertiary structure of MP were unfolding to different degrees after cold stress when compared to the control. The MP gel hardness reached a maximum when the cold stress reached 24 h. Furthermore, the quantitative proteomics results indicated that 20 up-regulated differentially abundant proteins (DAPs) were detected in 24 h when compared to control, specifically include myosin light chain 1 (MLC1) and skeletal muscle actin 6. Additionally, the combined analysis confirmed that MLC1 and skeletal muscle actin 6 might play key roles in hardening shrimp meat under cold stress. The results could provide a theoretical reference for the changes in crayfish muscle quality during cold chain transportation.

Metabolic plasticity improves lobster's resilience to ocean warming but not to climate-driven novel species interactions. Sci Rep 2022; 12:4412.

Abstract
Marine species not only suffer from direct effects of warming oceans but also indirectly via the emergence of novel species interactions. While metabolic adjustments can be crucial to improve resilience to warming, it is largely unknown if this improves performance relative to novel competitors. We aimed to identify if spiny lobsters—inhabiting a global warming and species re-distribution hotspot—align their metabolic performance to improve resilience to both warming and novel species interactions. We measured metabolic and escape capacity of two Australian spiny lobsters, resident Jasus edwardsii and the range-shifting Sagmariasus verreauxi, acclimated to current average—(14.0 °C), current summer—(17.5 °C) and projected future summer—(21.5 °C) habitat temperatures. We found that both species decreased their standard metabolic rate with increased acclimation temperature, while sustaining their scope for aerobic metabolism. However, the resident lobster showed reduced anaerobic escape performance at warmer temperatures and failed to match the metabolic capacity of the range-shifting lobster. We conclude that although resident spiny lobsters optimise metabolism in response to seasonal and future temperature changes, they may be unable to physiologically outperform their range-shifting competitors. This highlights the critical importance of exploring direct as well as indirect effects of temperature changes to understand climate change impacts.

Effectiveness of the Food-Safe Anaesthetic Isobutanol in the Live Transport of Tropical Spiny Lobster Species. FISHES 2022.

Abstract
The strong demand for live spiny lobsters in Asian markets is being met by long-distance airfreight. Holding lobsters out of water during transportation often results in mortalities due to the accumulation of metabolites, especially ammonia. This study examined the potential to improve the survival of tropical lobster species exported from India through the use of the food-safe aquatic anaesthetic isobutanol, both with and without cold stunning, typically used prior to live lobster transportation. The results of the study indicate that treatment with 50 ppm isobutanol in ambient seawater temperature (i.e., 28 °C) prior to simulated live transport for 22 h significantly reduces ammonia levels in the haemolymph in all four lobster species (Panulirus homarus, P. ornatus, P. versicolor and P. polyphagus) compared to lobsters treated with cold stunning (i.e., 16.5 °C) with and without 10 ppm isobutanol. Cold stunning at 16.5 °C combined with 10 ppm isobutanol reduced ammonia levels compared to cold stunning alone only in P. ornatus. All experimental lobsters were returned to ambient seawater after simulated transport and were alive after 48 h. These results indicate that isobutanol has the potential to be used to suppress metabolism during the live transport of tropical lobsters and to reduce mortalities during live transport.

Abstract
In an ocean warming hotspot off south-east Australia, many species have expanded their ranges polewards, including the eastern rock lobster, Sagmariasus verreauxi. This species is likely extending its range via larval advection into Tasmanian coastal waters, which are occupied by the more commercially important southern rock lobster, Jasus edwardsii. Here, thermal tolerances of these lobster species at two life stages were investigated to assess how they may respond to warming ocean temperatures. We found that the pattern, optimum and magnitude of thermal responses differed between performance measures, life stages and species. Sagmariasus verreauxi had a warmer optimal temperature for aerobic scope and escape speed than J. edwardsii. However, J. edwardsii had a higher magnitude of escape speed, indicating higher capacity for escape performance. There were also differences between life stages within species, with the larval stage having higher variation in optimal temperatures between measures than juveniles. This inconsistency in performance optima and magnitude indicates that single performance measures at single life stages are unlikely to accurately predict whole animal performance in terms of life-time survival and fitness. However, combined results of this study suggest that with continued ocean warming, S. verreauxi is likely to continue to extend its distribution polewards and increase in abundance in Tasmania.

Abstract
Effects of natural stressors such as copper (Cu2+), temperature, hypoxia, chloroform and adrenaline on physiological and biochemical responses were investigated in the Mediterranean green crab Carcinus aestuarii from tidal shallow waters of Narta Lagoon, Albania. For this purpose, hemolymph glucose levels, total and differential hemocyte count, in normal and eye-stalked individuals, exposed to above mentioned stressors like, were assessed. In addition, lysosomal membrane stability was evaluated as biomarker of hemocyte toxicity, with possible implications on crab immune response. Hemolymph glucose levels were significantly increased in all treatment groups with 1.25-to 3.5-fold above baseline levels of 37.8 ± 2.7 mgdL-1. Response times were being manifested within 30-120 min following exposure and recovery happened within 2 h of restoration of pretreatment conditions. Total hemocyte count (THC) and differential hemocyte count (DCH) showed a significant decrease for all stressors, except for copper, were an increase of semi-granular hemocyte fraction were recorded. Meanwhile, significant reduction of neutral red retention time (NRRT), in both eyestalk-ablated and exposed animals, were recorded, indicated the loss of hemocyte lysosomal membrane integrity. The responsiveness of hemolymph blood levels to all stressors, the decrease in total hemocyte count, as well as the loss of lysosomal membrane integrity demonstrated that exposure to environmentally realistic stressors placed a heavy metabolic load on C. aestuarii, modulating their immune competence and overall physiological wellness. Overall, results suggest that monitoring cellular and biochemical parameters like hemolymph glucose titres, TCH, DHC and NRRT, may be useful and sensitive means of evaluating the crustacean's ability to cope with the wide variety of environmental stressors through modulation of the immune parameters.

Abstract
In Atlantic Canada and other salmon-growing regions, treatment of sea lice infestations in salmon aquaculture is necessary to protect fish health. The product Salmosan®, which contains the organophosphate azamethiphos as the active ingredient, is a pesticide presently used for treatment against sea lice. It is applied as a bath treatment and then released into the surrounding seawater. The potential for lethality to non-target species following acute and chronic exposures to Salmosan® has been studied over the past decade, however, the potential for sublethal effects on lobsters remains a concern. Adult male lobsters were exposed to 0.06, 0.5, and 5µgL-1 azamethiphos for one hour, repeated five times, over 48h. Lobsters were assessed immediately after exposure and over six days of recovery. Inhibition of muscle cholinesterase activity was detected in lobsters exposed to 0.5 and 5µgL-1 azamethiphos. The 5µgL-1 dose was considered lethal (93% cumulative mortality). Significant changes in hemolymph plasma biochemistry were most apparent in the 5µgL-1 exposure group in the immediate post-exposure samples. Citrate synthase activity was significantly lower in muscles of the 0.5µgL-1 exposure group compared to control lobsters. Mean electron transport system and standard metabolic rates tended to be lower in muscle tissue of the 0.5µgL-1 exposure group than control group lobsters. These results suggest that sublethal effects on lobster energetics may occur under laboratory exposure conditions (i.e., concentrations and duration) considered environmentally relevant, which could result in impairment under natural conditions.

Abstract
Acute and chronic toxicity tests were conducted with sea cucumber (Apostichopus japonicus) exposed to heavy metals. Acute toxicity values (96 h LC50) were 2.697, 0.133, and 1.574 mg L−1 for Zn, Cu, and Cd, respectively, and were ranked in order of toxicity: Cu > Cd > Zn. Under chronic metal exposure the specific growth rates of sea cucumbers decreased with the increase of metal concentration for all the three metals. After acute metal exposure, the oxygen consumption rate (OCR) decreased. The OCRs in all groups were significantly different than control (P < 0.05) except in the group treated with 1.00 mg L−1 Zn (P < 0.05), where the increase of OCR was observed. The OCRs in groups chronically exposed to metals were significantly lower than that in the control group (P < 0.05). The activity of both pyruvate kinase (PK) and hexokinase (HK) in sea cucumbers followed: respiratory tree > muscle > intestine in natural sea water. After chronic Zn, Cu, and Cd exposure, the change pattern of HK and PK in respiratory tree, muscle, and intestine varied slightly. However, the activity of the enzyme showed a general trend of increase and then decrease and the higher the exposure concentration was, the earlier the highest point of enzyme activity was obtained.

Abstract
Sea cucumber is a commercially important marine organism in China. Of the different colored varieties sold in China, albino sea cucumber has the greatest appeal among consumers. Identification of factors contributing to albinism in sea cucumber is therefore likely to provide a scientific basis for improving the cultivability of these strains. In this study, two-dimensional liquid chromatography-tandem mass spectrometry coupled with isobaric tags for relative and absolute quantification labeling was used for the first time to quantitatively define the proteome of sea cucumbers and reveal proteomic characteristics unique to albino sea cucumbers. A total of 549 proteins were identified and quantified in albino sea cucumber and the functional annotations of 485 proteins have been exhibited based on COG database. Compared with green sea cucumber, 12 proteins were identified as differentially expressed in the intestine and 16 proteins in the body wall of albino sea cucumber. Among them, 5 proteins were up-regulated in the intestine and 8 proteins were down-regulated in body wall. Gene ontology annotations of these differentially expressed proteins consisted mostly of 'biological process'. The large number of differentially expressed proteins identified here should be highly useful in further elucidating the mechanisms underlying albinism in sea cucumber.

Int J Mol Sci 2014; 15:22405-20.

Abstract
Melatonin has been identified in a variety of crustacean species, but its function is not as well understood as in vertebrates. The present study investigates whether melatonin has an effect on crustacean hyperglycemic hormone (CHH) gene expression, oxygen consumption (VO2) and circulating glucose and lactate levels, in response to different dissolved-oxygen concentrations, in the crab Neohelice granulata, as well as whether these possible effects are eyestalk- or receptor-dependent. Melatonin decreased CHH expression in crabs exposed for 45 min to 6 (2, 200 or 20,000 pmol·crab−1) or 2 mgO2·L−1 (200 pmol·crab−1). Since luzindole (200 nmol·crab−1) did not significantly (p > 0.05) alter the melatonin effect, its action does not seem to be mediated by vertebrate-typical MT1 and MT2 receptors. Melatonin (200 pmol·crab−1) increased the levels of glucose and lactate in crabs exposed to 6 mgO2·L−1, and luzindole (200 nmol·crab−1) decreased this effect, indicating that melatonin receptors are involved in hyperglycemia and lactemia. Melatonin showed no effect on VO2. Interestingly, in vitro incubation of eyestalk ganglia for 45 min at 0.7 mgO2·L−1 significantly (p < 0.05) increased melatonin production in this organ. In addition, injections of melatonin significantly increased the levels of circulating melatonin in crabs exposed for 45 min to 6 (200 or 20,000 pmol·crab−1), 2 (200 and 20,000 pmol·crab−1) and 0.7 (200 or 20,000 pmol·crab−1) mgO2·L−1. Therefore, melatonin seems to have an effect on the metabolism of N. granulata. This molecule inhibited the gene expression of CHH and caused an eyestalk- and receptor-dependent hyperglycemia, which suggests that melatonin may have a signaling role in metabolic regulation in this crab.

Abstract
Sulfamethoxazole (SMZ) is one of the most widely employed sulfonamides. Because of the widespread use of SMZ, a considerable amount is indeed expected to be introduced into the environment. The cytotoxicity of SMZ relies mainly on arylhydroxylamine metabolites (S-NOH) of SMZ and it is associated with the production of reactive oxygen species (ROS). There is limited information about the toxic potential of SMZ at the cellular and molecular levels, especially in aquatic and/or non-target organisms. In the present study, the red swamp crayfish (Procambarus clarkii), being tolerant to extreme environmental conditions and resistant to disease, was used as a model organism to profile the molecular and physiological response to SMZ. Haemolymphatic-immunological parameters such as glucose serum levels and total haemocyte counts were altered; moreover, a significant increase in Hsp70 plasma levels was detected for the first time. Variations at the transcriptional level of proinflammatory genes (cyclooxygenase-1, COX 1, and cyclooxygenase-2, COX 2), antioxidant enzymes (glutathione-S-transferase, GST and manganese superoxide dismutase MnSOD), stress response and Fenton reaction inhibitor genes (heat-shock protein 70 HSP70, metallothionein, MT and ferritin, FT) were evaluated, and alterations in the canonical gene expression patterns emerged. Considering these results, specific mechanisms involved in maintaining physiological homeostasis and adaptation in response to perturbations are suggested.

A holistic view of dietary carbohydrate utilization in lobster: digestion, postprandial nutrient flux, and metabolism. PLoS One 2014; 9:e108875. [PMID: 25268641 PMCID: PMC4182579 DOI: 10.1371/journal.pone.0108875] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/29/2014] [Accepted: 08/26/2014] [Indexed: 12/20/2022] Open
Abstract
Crustaceans exhibit a remarkable variation in their feeding habits and food type, but most knowledge on carbohydrate digestion and utilization in this group has come from research on few species. The aim of this study was to make an integrative analysis of dietary carbohydrate utilization in the spiny lobster Panulirus argus. We used complementary methodologies such as different assessments of digestibility, activity measurements of digestive and metabolic enzymes, and post-feeding flux of nutrients and metabolites. Several carbohydrates were well digested by the lobster, but maize starch was less digestible than all other starches studied, and its inclusion in diet affected protein digestibility. Most intense hydrolysis of carbohydrates in the gastric chamber of lobster occurred between 2–6 h after ingestion and afterwards free glucose increased in hemolymph. The inclusion of wheat in diet produced a slow clearance of glucose from the gastric fluid and a gradual increase in hemolymph glucose. More intense hydrolysis of protein in the gastric chamber occurred 6–12 h after ingestion and then amino acids tended to increase in hemolymph. Triglyceride concentration in hemolymph rose earlier in wheat-fed lobsters than in lobsters fed other carbohydrates, but it decreased the most 24 h later. Analyses of metabolite levels and activities of different metabolic enzymes revealed that intermolt lobsters had a low capacity to store and use glycogen, although it was slightly higher in wheat-fed lobsters. Lobsters fed maize and rice diets increased amino acid catabolism, while wheat-fed lobsters exhibited higher utilization of fatty acids. Multivariate analysis confirmed that the type of carbohydrate ingested had a profound effect on overall metabolism. Although we found no evidence of a protein-sparing effect of dietary carbohydrate, differences in the kinetics of their digestion and absorption impacted lobster metabolism determining the fate of other nutrients.

Abstract
This study examined the effects of boat noise on the behavioural and biochemical parameters of the Mediterranean spiny lobster (Palinurus elephas). The experiment was conducted in a tank equipped with a video and audio recording system. 18 experimental trials, assigned to boat noise and control conditions, were performed using lobsters in single and group of 4 specimens. After a 1h habituation period, we audio- and video-recorded the lobsters for 1h. During the experimental phase, the animals assigned to the boat groups were exposed to boat noise pollution (a random sequence of boat noises). Exposure to the noise produced significant variations in locomotor behaviours and haemolymphatic parameters. Our results indicate that the lobsters exposed to boat noises increased significantly their locomotor activities and haemolymphatic bioindicator of stressful conditions such as glucose, total proteins, Hsp70 expression and THC when tested both singly and in groups.

Abstract
This study examined the effects of an acoustic stimulus on the haemolymph and agonistic behaviour of the red swamp crayfish, Procambarus clarkii. The experiment was conducted in a tank equipped with a video recording system using six groups (three control and three test groups) of five adult crayfish (30 specimens in total). After 1 h of habituation, the behaviour of the crayfish was monitored for 2 h. During the second hour, the animals in the test groups were exposed to a linear sweep (frequency range 0.1-25 kHz; peak amplitude 148 dB(rms) re. 1 μPa at 12 kHz) acoustic stimulus for 30 min. Exposure to the noise produced significant variations in haemato-immunological parameters as well as a reduction in agonistic behaviour.

Abstract
Nicking is used in fisheries to immobilize claws of brown crab (Cancer pagurus) in order to prevent cannibalism and fighting during storage. Nicking fractures the apodemes creating an open wound and damage to the internal claw tissues, which is the most valuable product of brown crab. In turn, this results in a reduction of quality of product and possibly compromises the host's defence mechanisms to other physiological challenges experienced throughout the post-harvest process. This study assessed the effects of nicking on the physiology and pathology of brown crab from the Irish fishery over 7 days. Results showed significantly elevated levels of muscle necrosis (P=0.005), total pathologies (P=0.022) and encirculating granulocytes in nicked crab compared to non-nicked crab. Mean glucose (212.0 μg/mL±108.4), lactate (36.52 μg/mL±38.74) and RI (11.05n±1.78) levels were higher in nicked crab indicating increased stress levels. Overall, histology results showed a significantly higher (P=0.022) occurrence of pathologies, such as melanised nodules, in nicked animals. In addition to an observed reduction in the quality of claw muscle, nicked crab also showed significantly higher (P=0.005) levels of necrosis in claw muscle. From the results of this study it is recommended that alternative retention methods are used.

Abstract
The effect of hypoxia and re-oxygenation on the mitochondrial complex F(O)F(1)-ATP synthase was investigated in the whiteleg shrimp Litopenaeus vannamei. A 660 kDa protein complex isolated from mitochondria of the shrimp muscle was identified as the ATP synthase complex. After 10h at hypoxia (1.5-2.0 mg oxygen/L), the concentration of L-lactate in plasma increased significantly, but the ATP amount and the concentration of ATPβ protein remained unaffected. Nevertheless, an increase of 70% in the ATPase activity was detected, suggesting that the enzyme may be regulated at a post-translational level. Thus, during hypoxia shrimp are able to maintain ATP amounts probably by using some other energy sources as phosphoarginine when an acute lack of energy occurs. During re-oxygenation, the ATPase activity decreased significantly and the ATP production continued via the electron transport chain and oxidative phosphorylation. The results obtained showed that shrimp faces hypoxia partially by hydrolyzing the ATP through the reaction catalyzed by the mitochondrial ATPase which increases its activity.

Abstract
A gene encoding Bombyx mori arginine kinase (BmAK) has been indentified differentially expressed in the midguts of Bombyx mori strain NB which is resistant to nucleopolyhedrovirus (BmNPV), strain 306 which is susceptible to NPV and a near isogenic line BC(8) with similar genetic background to 306 but resistant to NPV by two-dimensional gel electrophoresis (2-DE). In this study, we characterized the expression profiles of BmAK using RT-PCR and real-time quantitative PCR. The expression level of BmAK fluctuated in various developing stage and various tissue. Remarkably, the expression level of BmAK increased more than 10-fold 24 hours post inoculation (h p.i.) of NPV in strain NB and BC(8), while such increment was abraded in strain 306 although the basal expression level of BmAK in strain 306 was higher than that of strain NB and BC(8). Western blotting analysis using polyclonal antibody against BmAK verified such observation, and immunofluoresence analysis indicated for the first time that BmAK was mainly located to the cytoplasm or some structures in cytoplasm. These findings suggest that arginine kinase is involved in the antiviral process of Bombyx mori larvae against NPV infection.

Abstract
The aim of this research was to investigate influence of different environmental stressors, such as temperature increase, air exposure and food deprivation on DNA integrity of a bioindicator species, freshwater crayfish Astacus leptodactylus. DNA damage was measured in crayfish haemocytes using Comet assay and micronucleus test. Crayfish haemolymph was subsequentially sampled during their 7 days of exposure to increased temperatures (25 and 30 degrees C) and during 24 h of air exposure. Both groups were also monitored through the following 7 days of recovery period. Food deprived crayfish were monitored over a period of 2 weeks. Alterations of measured physiological and immunological haemolymph parameters (THC, lactate, glucose and protein concentration) indicated stress response in exposed crayfish. However, only the stress induced by increased temperature significantly increased DNA damage in freshwater crayfish while food deprivation or air exposure did not cause a significant genotoxic effect.

Abstract
SUMMARY
Callinectes sapidus (Rathbun), the Atlantic blue crab, commonly harbors low to moderate amounts of bacteria in hemolymph and other tissues. These bacteria are typically dominated by Vibrio spp., which are known to cause mortality in the blue crab. The dose-dependent lethality of an isolate of Vibrio campbellii was determined in crabs; the mean 48 h LD50 (half-maximal lethal dose) was 6.2×105 colony forming units g–1 crab. Injection of a sublethal dose of V. campbellii into the hemolymph of the crab resulted in a rapid and large depression (30–42%) of metabolic rate, which persisted for 24 h. Because gills are an organ of immune function as well as respiration, we were interested in how bacteria injected into the crab would affect the energetic costs associated with walking. Overall metabolism (aerobic and anaerobic) more than doubled in crabs walking for 30 min at 8 m min–1. The metabolic depression resulting from bacterial injection persisted throughout the exercise period and patterns of phosphagen and adenylate consumption within walking leg muscle were not affected by treatment. The ability of crabs to supply required energy for walking is largely unaffected by exposure to Vibrio; however, Vibrio-injected crabs are less aerobic while doing so. This depressed metabolic condition in response to bacteria,present during moderate activity, could be a passive result of mounting an immune response or may indicate an actively regulated metabolic depression. A compromised metabolism can affect the performance of daily activities, such as feeding and predator avoidance or affect the ability to cope with environmental stressors, such as hypoxia.

Abstract
In this proteomic analysis of gills from yellow head virus (YHV)-infected Penaeus vannamei, we identified 13 spots with up-regulated protein expression levels and five spots with down-regulated levels. LC-nanoESI-MS/MS indicated that the up-regulated proteins included enzymes in the glycolytic pathway, the tricarboxylic acid cycle and amino acid metabolism. The other up-regulated proteins were arginine kinase, imaginal disk growth factor (IDGF) and a Ras-like GTP binding protein. By contrast, expression levels were reduced for an SCP-calcium binding protein (SCP), actin-1, a valosin-containing protein, and Rab11. Time-course assays by real time RT-PCR revealed no significant increase in mRNA level of glycolytic enzymes and arginine kinase. However, a significant decrease in SCP mRNA was observed. The present results are consistent with previously published work and suggest that a decrease in SCP expression may play an important role in the shrimp response to viral infections in general.

Abstract
Homarus americanus is an important commercial species that can survive 2-3 days out of water if kept cool and humid. Once caught for commercial purpose and shipped around the world, a lobster is likely to be subjected to a number of stressors, including emersion and air exposure, hypoxia, temperature changes and handling. This study focused on the effect of transport stress and specifically at different animal body temperature (6 and 15 degrees C) and air exposure during commercial transport and recovery process in water. Animals were monitored, by hemolymph bleeding, at different times: 0 h (arrival time at plant) 3 h, 12 h, 24 h and 96 h after immersion in the stocking tank with a water temperature of 6.5+/-1.5 degrees C. We analysed the effects by testing some physiological variables of the hemolymph: glucose, cHH, lactate, total protein, cholesterol, triglycerides, chloride and calcium concentration, pH and density. All these variables appeared to be influenced negatively by high temperature both in average of alteration from the physiological value and in recovering time. Blood glucose, lactate, total protein, cholesterol were significantly higher in the group with high body temperature compared to those with low temperature until 96 h after immersion in the recovery tank.

Abstract
Osmolytes are a series of different kinds of small molecules that can maintain the correct conformation of protein by acting as molecular chaperons. In this study, the protective effects of four compatible osmolytes, i.e., proline, sucrose, DMSO and glycerol, were studied during arginine kinase (EC 2.7.3.3) unfolding and aggregation. The results showed that all the osmolytes applied in this study obviously prevented AK unfolding and inactivation that was due to a GdnHCl denaturant by reducing the inactivation rate constants (k(i)), increasing the transition free energy changes (DeltaDeltaG(i)) and increasing the value for the midpoint of denaturation (C(m)). Furthermore, the osmolytes remarkably prevented AK aggregation in a concentration-dependent manner during AK refolding. Our results strongly indicated that osmolytes were not only metabolism substrates, but they were also important compounds with significant physiological protective functions for proteins, especially in some extremely harsh environments.

Abstract
Postprandial changes in haemolymph glucose concentration ([Glc]H) were measured in 4-day-fasted juvenile intermoult spiny lobsters, Jasus edwardsii, provided with meals composed of glycogen, maltose, sucrose, glucose, or fructose in a gelatine base, or with gels of the algal glycans agar, alginate and carrageenan. Baseline [Glc]H was 0.61+/-0.02 mmol L(-1). After consumption of glycogen, maltose or sucrose, [Glc]H approximately doubled, peaked after 3 h and returned to baseline between 12 and 24 h. Glucose and fructose meals were followed by periods of sustained hyperglycaemia lasting more than 24 h (peaking at approximately 2.5 times baseline at 6 and 3 h respectively). Suggested explanations for augmented hyperglycaemic responses to glucose and fructose are: 1) these monosaccharides by-passed contact digestion and absorption in the R-cells of the digestive gland, directing them away from storage and toward transepithelial scavenging routes; or 2) glucose and fructose directly elicited release of crustacean hyperglycaemic hormone via a chemosensory reflex. Agar and alginate induced significant postprandial glycaemic responses, consistent with reports of carbohydrases in this species and indicating their potential for inclusion in artificial diets as both binders and energy sources. Carrageenan, a highly sulphated galactan, did not produce a glycaemic response. The measurement of glycaemic responses is a quick method of obtaining nutritional information on carbohydrates considered for inclusion in formulated diets prior to lengthy growth trials.

Abstract
Intermittent locomotion by terrestrial crustaceans may under specific circumstances increase walking distance and may allow partial re-oxidization of anaerobic products, and replenishment of ATP and arginine phosphate. The Christmas Island red crab G. natalis undertakes a substantial breeding migration each year. The leg muscles of G. natalis subjected to bouts of 2.5 min walking and 2.5 min rest were severely anaerobic. Adenylate energy charge and the large arginine phosphate stores were greatly reduced. Walking for 4 min with pauses of only 1 min exacerbated the anaerobiosis and utilised 50% of the endogenous muscle glycogen. Post-exercise, the adenylate energy charge recovered before the arginine phosphate charge and a large and persistent hyperglycaemia accompanied the restoration of glycogen. Arginine phosphate functioned as a large, longer term, energy reservoir-almost as part of the adenylate pool. Gluconeogenesis is yet to be generally substantiated in decapod crustaceans but G. natalis appears to remove lactate slowly and to reincorporate exogenous glucose into muscle glycogen in the same time frame as lactate removal from the haemolymph. The 4:1 exercise/pause regimen facilitated access to energy stores and increased walking distance, and it allowed L-lactate and H(+) efflux from the muscle during pausing. These responses are similar to those of G. natalis in the field, except during the migration when walking was entirely aerobic. Determinations of adenylate, fuel and arginine phosphate reserves and usage during the migration are required together with more detailed behavioral analysis to resolve the dichotomy in metabolic response.

Abstract
The larval life of the spiny lobster Jasus edwardsii is one of the longest and most complex of any marine organism and is poorly understood due to the difficulty of studying cryptic, pelagic organisms. Hence, the capacity for active swimming in the phyllosoma, puerulus and juvenile stages and the use of possible metabolic fuel reserves was inferred from a number of enzyme activities, including citrate synthase, lactate dehydrogenase, and HOAD. High activities of CS and LDH in abdominal tissues of Stage 11 phyllosoma and pueruli are consistent with a capacity to commence active on-shore movement. The activities of LDH and HOAD showed positive allometry while CS was independent of body mass. The body mass dependence of LDH activity may reflect the developing ability of the lobster to initiate brief escape manoeuvres, and the scaling of HOAD reflects an increased use of lipid fuel reserves. Aerobic enzyme activities were higher in abdominal tissues than in cephalic tissues of pelagic pueruli, but high activities appear in the cephalic tissues of juveniles. These changes mirror a developmental shift in activity from pelagic oceanic swimming to a benthic existence on the seabed of the near shore. The low LDH activity in pueruli confirmed previous findings that they have limited feeding capacity, with carbohydrate contributing little towards the major energy reserves. The highest LDH activities occur in the abdominal muscles of juveniles and correlate with rapid tail-flicking escape behaviour. The activities of HOAD increased throughout development, and in the abdominal tissues of juveniles, may reflect lipid transformation and accumulation as an energy reserve. Enzyme activities, therefore, provide useful information concerning migratory behaviour that is presently unavailable from ecological studies.
