Abstract
The present study evaluates the endocrine effect in flatfish through vitellogenin (vtg) gene expression and its association with pollutants data obtained from fish muscle and sediment from two regions in the Gulf of Mexico (GoM): Perdido Fold Belt (northwestern) and the Yucatan Peninsula (southeast). The results revealed induction of vtg in male flatfish in both geographical regions with different levels and patterns of distribution per oceanographic campaign (OC). In the Perdido Fold Belt, vtg was observed in male fish during four OC (carried out in 2016 and 2017), positively associated with Pb, V, Cd and bile metabolites (hydroxynaphthalene and hydroxyphenanthrene). In the Yucatan Peninsula, the induction of vtg in males was also detected in three OC (carried out in 2016 and 2018) mainly associated with Ni, Pb, Al, Cd, V and polycyclic aromatic hydrocarbons. Ultimately, estrogenic alterations could affect reproductive capacity of male flatfish in the GoM.

Differential blood cells associated with parasitism in the wild puffer fish Lagocephalus laevigatus (Tetraodontiformes) of the Campeche Coast, southern Mexico. Parasitol Res 2023; 123:24.

Abstract
In aquaculture conditions, severe parasitic infections cause negative impacts on fish health and economic losses. The parasite load has been associated with anemia, which reduces the number of erythrocytes in fish. Therefore, the evaluation of hematological parameters as a feasible tool for diagnosing and monitoring fish health allows us to determine the indirect effect of parasites on the health status of fish. Our aim was to evaluate changes in the blood cell parameters of Lagocephalus laevigatus associated with parasitism. A total of 99 puffer fish were collected from the coast of Seybaplaya, Campeche. Each fish had 20 µl of peripheral blood drawn, and blood smears were performed in triplicate. The smears were stained with Giemsa stain, and a quantitative analysis of blood cells (erythrocytes, leukocytes, and monocytes) was obtained with an optical microscope at 100 ×. The parasites recovered from each fish were fixed and identified, and the infection parameters were calculated. Through generalized additive model analysis (GAMLSS), we observed that the infection intensity of puffer fish influenced changes in hematological parameters, principally in erythrocytes, neutrophils, thrombocytes, the total fish length, and the condition factor of the fish. In conclusion, this is the first study that provides baseline data on the hematological parameter variations in uninfected and infected L. laevigatus, the tropical wild puffer fish, as well as the possible effects on fish health. It is necessary to establish reference hematological patterns in wild populations for diagnosis and timely management with emphasis on aquaculture fish.

Trace element and lipidomic analysis of bottlenose dolphin blubber from the Yucatan coast: Lipid composition relationships. CHEMOSPHERE 2022; 299:134353. [PMID: 35314180 DOI: 10.1016/j.chemosphere.2022.134353] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/07/2021] [Revised: 02/27/2022] [Accepted: 03/15/2022] [Indexed: 06/14/2023]
Abstract
Bottlenose dolphins (Tursiops truncatus) are found in coastal and estuarine ecosystems where they are in continuous contact with multiple abiotic and biotic stressors in the environment. Due to their role as predators, they can bioaccumulate contaminants and are considered sentinel organisms for monitoring the health of coastal marine ecosystems. The northern zonal coast of the Yucatan peninsula of Mexico has a high incidence of anthropogenic activities. The principal objectives of this study were two-fold: 1) to determine the presence of trace metals and their correlation with lipids in bottlenose dolphin blubber, and 2) to use a lipidomics approach to characterize their biological responses. Levels of trace elements (Al, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Se, Cd, Pb) were analyzed using ICP-MS and lipids were measured using a targeted lipidomics approach with LC-MS/MS. Spearman correlation analysis was used to identify associations between lipids and trace elements. The influences of gender, stranding codes, presence of stomach content, growth stages and body length were also analyzed. Blubber lipid composition was dominated by triacylglycerols (TAG). Our results demonstrated the presence of heavy-metal elements such as Cd and As, which were correlated with different lipid species, mainly the ceramides and glycerophospholipids, respectively. Organisms with Cd showed lower concentrations of ceramides (CER, HCER and DCER), TAG and cholesteryl esters (CE). Trace elements Cr, Co, As and Cd increased proportionately with body length. This study provides a novel insight of lipidomic characterization and correlations with trace elements in the bottlenose dolphin which might contribute to having a better understanding of the physiological functions and the risks that anthropogenic activities can bring to sentinel organisms from coastal regions.
