Abstract
Background: Mystacoleucus padangensis living in Lake Singkarak, Indonesia, has high potential market demand but is threatened by overfishing and has not been successfully cultured. This study describes the first broodstock development, induced breeding, and larval rearing of M. padangensis. Methods: A total of 1,000 female and 1,000 male broodfish were collected from the wild and reared in two concrete ponds (128 m 2) at the Centre for Biodiversity Conservation, P.T. Semen Padang, Indonesia. The broodfish were fed commercial feed to satiation at 09:00 and 17:00 h. The females (average weight 7.56 ± 0.85 g) and males (4.86 ± 1.20 g) were selected at a ratio of 1:4 (female:male), and gonad maturation was induced with a single dose of GnRH analogue (Ovaprim) of 0.1 ml/fish. At 16 h after hormone injection, eggs were collected individually into a plastic vessel. Spermatozoa were collected with sterile syringes. Eggs were fertilized using the "dry" method, and 0.5 ml samples (equal to 100 eggs) were taken. The eggs were incubated in a plastic strainer with a water volume of 1.57 litres and placed in a tarpaulin pond with a volume of 150.72 litres. Results: The overall hatching rate was 78.93 ± 4.13%. The newly hatched larvae were 3900.81 µm long, with a yolk sac of 82881.480 µm 2. The mouth opened at 72 days post hatching (DPH) with a gape measuring approximately 61.880 µm. The protocol of larval feeding started with artificial feed, followed by Artemia nauplii up to 30 DPH. Weaning of larvae started at 4 DPH. Larvae started metamorphosis by 15 DPH and ended by 22 DPH when the larvae reached 7430.27 µm. Larval rearing resulted in an average survival rate of 28.4 ± 3.04%. Conclusions: Its successful spawning induction and high larval hatching and survival rates make M. padangensis an excellent aquaculture candidate.

Abstract
Despite the efforts to end malnutrition through intensive agriculture of caloric crops, micronutrient deficiencies and other forms of malnutrition persist in vulnerable communities worldwide. Nutrition-sensitive agriculture (NSA) interventions are recognized as chances to address the causes of malnutrition. In this work, the different types of NSA interventions were explored, as well as the pathways through which they can improve nutrition (e.g., increasing biofortified crops and income generation via agricultural sales for a positive impact on access to nutritious foods, and simultaneously involving nutrition education to improve care practices and eventually nutritional status). Some NSA interventions focus on one pathway. Well-designed interventions, however, should follow multi-pathway approaches targeting the underlying causes of undernutrition within the selected population. The circumstances in which certain indicators should be used to measure the impact of an NSA intervention in each stage of the full pathway were also explained, as well as the need of enhancing the design of such interventions. Multi-criteria decision analysis (MCDA) has been employed to solve agriculture-related issues, but it has not been used to identify the optimal types of NSA interventions, metrics, and indicators based on the context of the community, priorities and objectives of the project managers and designers, etc.

Abstract
Marine fish are good source of essential macro- and micronutrients and major food items in coastal areas in Bangladesh. However, there is no review that details the nutritional value of marine fish in Bangladesh. Therefore, this review focuses on the nutrient composition of marine fish in Bangladesh and how the marine fish can address common nutrient deficiencies among women and children. Nutrient composition data was collected through literature searching in databases and source, including PubMed, Web of Science, Google Scholar, ScienceDirect, WorldFish, and Bangladesh-based database Banglajol. Calculation was carried out to present how one serving marine fish could potentially meet the daily requirement of protein, iron, zinc, calcium, vitamin A, and docosahexaenoic acid (DHA) for pregnant and lactating women and children aged 6-23 months. A total of 97 entries covering nutrient composition analysis of 67 individual fish species were extracted from 12 articles published between 1993 and 2020. Included articles contained analysis of proximate composition, vitamins, minerals, fatty acids, and amino acid. Twelve minerals and nine vitamins were analyzed and reported. The average energy, protein, fat, and ash content per 100 g edible raw marine fish was 343.58 kJ, 16.76 g, 4.16 g, and 2.22 g, respectively. According to available data, marine fish are good sources of protein, zinc, calcium, and DHA. Pelagic small fish, which are mainly captured by artisanal small-scale fishers, had more nutritional value than other categories of fish. Furthermore, marine small fish were found more nutritious than commonly consumed freshwater fish types in Bangladesh, including major carps, introduced carps, and tilapia. Therefore, the study concludes that marine fish have high potential to address malnutrition in Bangladesh. There was scarcity of literature regarding the nutrient composition of marine fish in Bangladesh and in South Asia as a whole, so more comprehensive quality research in this area is recommended.

Abstract
We empirically ascertained the impact of COVID-19 pandemic on fisheries sector of Sri Lanka, focusing on the year 2020 which helps identify changes in production and income of the sector. Daily wage and monthly income of stakeholders in the pre-pandemic period are well above the national minimum daily wage and monthly income of the workers in Sri Lanka. Defensive measures taken to curb rapid spread of COVID-19 have given a shock to all stakeholders of the sector. Health and safety measures imposed to avert the spreading of pandemic have compelled the stakeholders to incur extra costs. Study indicates significant impact of the pandemic on production and income of the stakeholders in the fisheries value chain. Comparison of total fish production during 2015-2020 confirms the impacts on the sector and, changes in fish production and income in 2020 completely coincide with COVID-19-time line. Severity of impacts is stakeholder and area specific. Fisheries districts in western province are highly impacted over the other districts. DPSIR framework captures the status of social system and unfolds existing problems in the sector, enabling decision-makers to take policy decisions for future actions. Government of Sri Lanka has taken several steps to revive the sector, and stakeholders have shown an adaptive capacity to cope with impacts of the pandemic. Present crisis in the sector is far from over and, short-term impacts are likely to be followed by long-term crises, thus measures should be taken to revive the sector in new normal conditions and the post-pandemic era.

Abstract
Fish is an important source of proteins, vitamins, minerals, and polyunsaturated fatty acids for nutrition adequacy. However, fish is a major link to dietary metal exposure in humans. This study describes the content of eight trace elements (As, Cd, Cr, Cu, Ni, Pb, Zn, and Hg) in eleven commercial fish species from the Missouri market and evaluated the health risks of fish muscle consumption in the adult population. Total mercury (THg) in muscle was quantified by AAS and ICP-OES was used for other elements. The recovery rates of elements from DOLT-5 reference material ranged from 83% to 106%. Of all the 239 fish samples analyzed, trace element concentrations (mg/kg wet weight) in muscle were in the following ranges: As < LOD—17.5; Cd: 0.016–0.27; Cr: 0.023–0.63; Cu: 0.034–1.06; Ni: <LOD—1.05; Pb: <LOD—0.82; Zn: 0.99–6.18; and THg: 0.0001–0.27. The levels of As, Cd, Cr, and Pb, in some samples representing several species, were above the respective limit. Kruskal-Wallis non-parametric test results showed statistically significant (p < 0.05) differences in Cd, As, Cr, Ni, and Hg concentrations among some pelagic and demersal species. Besides, median Hg and As levels differed (p < 0.05) between farmed and wild fish, with higher values observed in the wild fish samples. At times, the estimated weekly intake (EWI) for As was exceeded in certain pelagic and demersal fish. Arsenic content in some demersal fish species posed potential toxicity. Further, the incremental (ILCR) and cumulative (∑ILCR) cancer risks for As, Cr, and Ni exceeded the benchmark (10−5), which is a concern. Limited consumption of demersal fish species may protect adult consumers from potential health hazards. Accumulation of trace elements in eleven fish species from the market. As, Cd, Cr, and Pb in some species, at times, exceeded the prescribed limits. Elemental levels, at times, differed (p < 0.05) among pelagic and demersal species. Hg and As levels, higher in wild fish, differed (p < 0.05) from those of farmed fish. Weekly intakes of seven elements from muscle were below the respective PTWI value. Increased consumption per week of demersal fish species may pose health risks.

Abstract
This study aimed to provide the very first description of the current scenario of knowledge, attitudes, and practices (KAP) concerning the food safety and hygiene subjects among wet fish handlers (WFHs) and dry fish handlers (DFHs) in Cox's Bazar, Bangladesh. Data collection was performed through the application of face-to-face interviews with 234 WFHs and 258 DFHs. The overall score of the correct answer assessed components was 55.95% and 57.05% in WFHs and DFHs, respectively. Among the different knowledge categories, both the respondents showed the highest positive response in the time, temperature, and quality control category and the lowest positive responses noted in the foodborne disease occurrence category. For attitudes, obtained results showed positive attitude with a mean score of 37.82 ± 4.28 and 35.58 ± 5.48 for WFHs and DFHs, respectively. The WFHs gained a mean score of 23.08 ± 4.24 for practices, and the score was 22.78 ± 4.47 in the case of DFHs. A positively significant correlation coefficient (r s) was observed among fish handlers' KAP of 0.326-0.584. Although the association between the three levels was acceptable, several food safety principles and hygiene practices remained unsatisfactory. These findings highlighted the need for rapid action to enhance food safety and hygiene KAP through an intensive training program to assure the production of safe fisheries products for human consumption.

Abstract
Poor understanding of market demand is a key factor in the recurrent failure of many production-orientated aquaculture interventions. In the Dry-Zone of Sri Lanka stocking-based fisheries enhancements in small-scale reservoirs have been promoted by the State since the 1980's with no evidence of sustainable adoption. Through an evaluation of positive (actual) and normative (aspirational) consumer preferences for inland fish and its substitutes, we aimed to assess underlying reasons for this recurrent failure and future prospects for the policy and rural food-security. Work commenced with a detailed scoping-analysis to establish socio-economic context and a sample frame for systematic surveys. Consumption recall and preference ranking/scoring techniques were applied in two iterative survey phases across 6 villages of Northwest Province. Totals of 39 and 165 respondents were surveyed across the two phases with selection stratified on age, gender, caste and wealth criteria. Results underscored the importance of inland fish to rural food security. Fresh inland fish was consumed by 60% of all respondents at least once per fortnight and by 82% at least once per month with tilapias accounting for 75–85% of meals. Preference for inland fish compared over similarly priced substitutes is attributable to their freshness at point of sale above any other intrinsic product quality. Larger inland and marine fish were more popular than smaller sizes of the same varieties though poorer households consumed lower cost small fresh tilapia (<180 g) and dried marine fish at higher frequency. Common carp an exotic candidate for culture-based reservoir stocking enhancements, held an intermediate position. National policies on inland aquaculture development and rural food security are discussed and recommendations made in the light of these findings.

Abstract
The global market for seafood alternatives is witnessing an exponential growth. Nevertheless, the nutritional quality of such products is scarcely studied. Thus, this study aimed to evaluate, for the first time, the nutritional quality of seafood alternatives launched in the global market from 2002 to 2021 and to compare them with the conventional seafood products. Using the Mintel Global New Products Database, the nutritional information of seafood alternatives (i.e., tuna, shrimps, calamari, fish fingers, fish sticks, salmon, caviar, and fillet) was retrieved, and compared with conventional products. A total of 149 seafood alternatives were identified, of which 83 items had complete mandatory nutritional labeling. Conventional products (n = 973) were also collected, from which 130 products have a complete nutritional labeling. Results revealed that tuna, shrimps, caviar and fillet alternatives contained significantly less protein than conventional products, while calamari, fish fingers, fish sticks and salmon alternatives had similar amounts to their conventional counterparts. Salt content was significantly higher in tuna, fish fingers and sticks substitutes, but lower in shrimps, calamari and caviar alternatives compared to conventional products. Overall, the commercially available seafood alternatives have nutritional strengths and some shortcomings to be further addressed in future research such as low protein content. Additionally, fortification of seafood alternatives with micronutrients, such as omega-3 fatty acids and vitamins (A, B, and D), should be considered to ensure a nutritional equivalence with the conventional products.

Abstract
Hypertension is a threatening chronic disease, which become a global killer among the adult population. The mortality rate increasing day by day even several Angiotensin I-converting enzyme (ACE) inhibitor drugs were introduced. Bioactive peptides derived from aquatic resources exhibits potential ACE inhibitory activity. The objective of this work is to report the purification and molecular docking studies of angiotensin-I converting enzyme (ACE) inhibitory peptide isolated from shortfin scad (Decapterus macrosoma) waste protein hydrolysate (SWH), enzymatically prepared by using alcalase. The purification process included ultrafiltration, gel filtration and reverse phase high performance liquid chromatography (RP-HPLC). Results showed that ultra-filtered peptide fraction (< 3 kDa) possessed the highest ACE inhibitory activity, followed by the fraction 14 by gel filtration. Fraction P obtained by RP-HPLC, with the amino acid sequence of RGVGPVPAA (IC50 = 0.20 mg/ml) was identified. In terms of ACE inhibition, the Lineweaver-Burk plot showed that the SWH peptide obtained acted as a competitive ACE inhibitor. The molecular docking studies showed that the SWH peptide exhibit hydrogen bonds and Pi-interactions with ACE by Z-dock scores. These results showed that the purified peptide isolated from shortfin scad waste hydrolysate has potential antihypertensive properties which could potentially be used as functional food ingredients.

Abstract
The changes in the feed of farmed Atlantic salmon (Salmo salar) towards a more plant-based diet affect the nutritional value of the fillets. By compiling the contents of a range of nutrients in 1108 samples of Norwegian farmed Atlantic salmon collected between 2005 and 2020, we found that the median contents of eicosapentaenoic acid (EPA) + docosahexaenoic acid (DHA) have decreased by > 60%. However, farmed Atlantic salmon remains a considerable source of EPA and DHA, with one and two portions being sufficient to meet the weekly adequate intake of EPA and DHA for adults (175 g) and two-year-olds (80 g), respectively. Farmed Atlantic salmon also remains a considerable source of protein, selenium, vitamin B12, and vitamin D3. Together, we demonstrate that farmed Atlantic salmon can contribute substantially to the nutrient intake of the consumers. These data are important for the Norwegian food composition table and future risk-benefit assessments on fatty fish consumption.

Abstract
Fish represent an important part of the Sri Lankan and Bangladeshi diet. However, fish is also a source of contaminants that may constitute a health risk to consumers. The aim of this study was to analyse the contents of arsenic, cadmium, mercury, and lead in 24 commonly consumed marine fish species from the Bay of Bengal and to assess the potential health risk associated with their consumption. Mercury and lead contents did not exceed the maximum limits for any of the sampled species, and consumer exposure from estimated daily consumption was assessed to be minimal for adults and children. Numerous samples exceeded the maximum limit for cadmium (58%), particularly those of small size (≤25 cm). However, consumer exposure was insignificant, and health assessment showed no risk connected to consumption. These data represent an important contribution to future risk/benefit assessments related to the consumption of fish.

Abstract
In a breastfed infant, the main source of vitamin D comes from the mother. Thus, maternal vitamin D deficiency is the key reason for vitamin D deficiency (VDD) and rickets during infancy. As they grow older, inadequate sun exposure, diet and lack of supplements also contribute. Individuals with darker skin require at least three to five times longer exposure to the sun than a person with lighter skin to produce adequate endogenous vitamin D. Not many food items naturally contain vitamin D; most of those are less affordable to the poor. We report an 18-month-old child with vitamin D deficiency rickets during strict self-isolation measures during the coronavirus disease 2019 (COVID-19) pandemic. Prolonged periods of confining indoors, low dietary intake of vitamin D, economic distress, maternal deficiency, and nonsupplementation could have contributed to vitamin D deficiency rickets in this child. During an unprecedented pandemic of this nature, simple sun exposure and diet advice may suffice for most. This case report highlights the importance of strengthening individuals and communities with information and formulating strong public health policies to prevent vitamin D deficiency.

Abstract
BACKGROUND There is growing recognition of the need for fish to be better integrated into nutrition-sensitive strategies for addressing malnutrition. Fish are overwhelmingly produced by the small-scale sector, which supports food and nutrition security directly through the provision of fish and indirectly through the generation of income which can be used to purchase other desired foods. However, there has been relatively little research on the extent of food and nutrition security in specialised fishing communities. This study assessed food and nutrition security among households in specialised fishing communities in Komodo District, eastern Indonesia. METHODS We assessed the seasonal nutrition quality of household diets using the Food Consumption Score for nutritional analysis and food insecurity using the Household Food Insecurity Access Scale in 66 households across three communities, using a modified cluster sampling strategy. We calculated and generated descriptive statistics for these indicators with Microsoft Excel and ran a logistic generalized linear mixed model to determine factors associated with severe food insecurity using SPSS. We used semi-structured interviews and focus group discussions to understand perceptions of, change over time, and strategies for dealing with food shortfalls. RESULTS While most households have acceptable access to nutritious foods, especially protein and heme iron-rich foods, nearly one half of households consumed vitamin A rich foods on less than 3 days of the 7-day recall period in either season. More than half of households reported experiencing a moderate or severe level of food insecurity, with higher food insecurity in the wet season. Low maternal education (OR: 3.8, 95%CI 1.5-9.9) and lower household wealth (OR: 0.5, 95%CI 0.3-0.9) were found to be associated with a severe level of food insecurity. Household's consumptive and non-consumptive response strategies reflect adaptation to chronic food insecurity but are nutritionally and economically unsustainable. CONCLUSION Households in specialised fishing communities in Komodo District consumed diets with low diversity and experienced high levels of food insecurity. There is a need for culturally-appropriate nutrition-sensitive strategies to enhance food and nutrition security in vulnerable fishing communities.

Composition of nutrients, heavy metals, polycyclic aromatic hydrocarbons and microbiological quality in processed small indigenous fish species from Ghana: Implications for food security. PLoS One 2020; 15:e0242086.

Abstract
The triple burden of malnutrition is an incessant issue in low- and middle-income countries, and fish has the potential to mitigate this burden. In Ghana fish is a central part of the diet, but data on nutrients and contaminants in processed indigenous fish species, that are often eaten whole, are missing. Samples of smoked, dried or salted Engraulis encrasicolus (European anchovy), Brachydeuterus auritus (bigeye grunt), Sardinella aurita (round sardinella), Selene dorsalis (African moonfish), Sierrathrissa leonensis (West African (WA) pygmy herring) and Tilapia spp. (tilapia) were collected from five different regions in Ghana. Samples were analyzed for nutrients (crude protein, fat, fatty acids, several vitamins, minerals, and trace elements), microbiological quality (microbial loads of total colony counts, E. coli, coliforms, and Salmonella), and contaminants (PAH4 and heavy metals). Except for tilapia, the processed small fish species had the potential to significantly contribute to the nutrient intakes of vitamins, minerals, and essential fatty acids. High levels of iron, mercury and lead were detected in certain fish samples, which calls for further research and identification of anthropogenic sources along the value chains. The total cell counts in all samples were acceptable; Salmonella was not detected in any sample and E. coli only in one sample. However, high numbers of coliform bacteria were found. PAH4 in smoked samples reached high concentrations up to 1,300 μg/kg, but in contrast salted tilapia samples had a range of PAH4 concentration of 1 μg/kg to 24 μg/kg. This endpoint oriented study provides data for the nutritional value of small processed fish as food in Ghana and also provides information about potential food safety hazards. Future research is needed to determine potential sources of contamination along the value chains in different regions, identify critical points, and develop applicable mitigation strategies to improve the quality and safety of processed small fish in Ghana.

Abstract
Fish and seafood may play an important role for nutrition and food security as they contain essential vitamins, minerals, and essential fatty acids. The aim of this study was to describe the nutrient composition, including fatty acids, amino acids, vitamins, and minerals, in commonly consumed fish species (fillet- and whole fish samples) sampled off the Northwest African coast. Furthermore, we assessed the species' contributions to the recommended nutrient intake (RNI) values from the World Health Organization (WHO). Samples of commercially important fish species (Sardina pilchardus, Engraulis encrasicolus, Trachurus trachurus, Pagellus acarne) were collected using trawling on the R/V Dr. Fridtjof Nansen in May 2017 and analyzed for nutrients at the Institute of Marine Research as individual and composite samples. All the analyzed fish species were good dietary sources of several vitamins and minerals and whole fish were substantially more nutrient dense than fillet samples, especially with regard to vitamin A, iodine, zinc, calcium, and iron. Including 100 g of sardine or anchovy (whole fish) in the diet, would contribute substantially to the RNI for vitamin B12, vitamin D and vitamin A, EPA and DHA as well as the minerals iodine, zinc, and calcium. This study shows that fish consumed with skin, bone, and viscera may be very nutrient dense and important for local food and nutrition security.

Abstract
Seafood plays a central role in global food and nutrition security. However, there is a lack of data on the concentration of nutrients and contaminants in fish and other seafood, especially in low- and middle-income countries. In order to assess the potential risks and benefits associated with seafood intake, reliable and up-to-date food composition data is crucial. The quality of food composition data is affected by several factors, such as sampling protocols and the suitability and quality of the methods applied for sample preparation and analysis. In this paper, we describe the sampling methodology and protocols related to the sampling of fish and other seafood and the corresponding analytical methods used to analyse the nutrient and contaminant content of such species. For nutrients, the determination of protein, fat, ash, energy, fatty acids, cholesterol, and amino acids is described, in addition to analyses for determination of the vitamin and mineral content in fish and other seafood. For contaminants, analyses for the determination of organic pollutants and microplastics are described. The methodology described in this paper is used for sampling data through scientific surveys in low- and middle-income countries with research vessel Dr. Fridtjof Nansen under the EAF-Nansen Programme. The Programme aims to improve knowledge on the nutritional composition of fish and ensure the fish is safe to consume.In this paper, we describe the sampling protocols used for sampling fish and other seafood during scientific surveys under the EAF-Nansen Programme. This paper describes the methodology and quality control for analysing nutrients and contaminants in fish and other seafood.

Abstract
Fish is a major part of the Bangladeshi diet, but data on the nutrient composition of marine fish species are sparse. Mesopelagic fish may be a new potential resource of food and nutrients; however, nutrient composition data are lacking. The aim of this study was to provide nutrient composition data of fish species sampled off the coast of Bangladesh and determine their potential contribution to recommended nutrient intakes (RNI). Seven species from the pelagic, mesopelagic, and demersal zones were sampled from the coast of Bangladesh with Dr. Fridtjof Nansen in 2018. Three pooled samples containing 15-840 individuals from each species were analysed at the Institute of Marine Research, Norway. The demersal species contained substantially lower concentrations of nearly all nutrients, whereas the mesopelagic species generally were more nutrient dense. All species, except for the demersal species Bombay duck (9% dry matter), were found to contribute ≥100% to the RNI of vitamin B12, eicosapentaenoic acid, docosahexaenoic acid, and selenium. All species, except for the demersal fish species, contributed ≥25% to the RNI of six or more nutrients. The data presented in this paper are an important contribution to the Bangladeshi food composition table and contribute to the understanding of fish as an important source of micronutrients.

Abstract
Fish is a rich source of several important nutrients and an important part of the otherwise plant-dominated diet present in Angola. However, fish may also be a source of contaminants. The aim of this study was to analyse the nutrient contents and the levels of chemical contaminants, including arsenic, cadmium, mercury, and lead, in five commonly consumed marine fish species sampled during a survey with the research vessel Dr. Fridtjof Nansen in Angola. The species' contribution to recommended nutrient intakes (RNI) for women and children was assessed and compared to that of food products of terrestrial animal origin. All the sampled species are good sources of protein and micronutrients if included in the diet, and inter-species variation is evident. The species were identified to contribute 5-15% of the RNI for calcium, iron, iodine, and zinc and exceeded the contribution to protein and iron intakes of food products of terrestrial animal origin. Furthermore, the potential consumer exposure to chemical contaminants in the species was assessed. None of the species exceeded the maximum levels for cadmium, mercury, and lead, and the potential consumer exposure to cadmium and methylmercury was considered low. The data presented in this study represent an important contribution to African food composition tables.
