Effects on Biochemical Parameters and Animal Welfare of Dusky Grouper ( Epinephelus marginatus , Lowe 1834) by Feeding CTX Toxic Flesh

Ciguatera is a foodborne disease caused by ciguatoxins (CTXs), produced by dinoflagellates (genera and ), which bioaccumulate in fish through the food web, causing poisoning in humans. Currently, the physiological mechanisms of the species with the highest amount of toxins in their adult stage of li...

Zusammenfassung:Ciguatera is a foodborne disease caused by ciguatoxins (CTXs), produced by dinoflagellates (genera and ), which bioaccumulate in fish through the food web, causing poisoning in humans. Currently, the physiological mechanisms of the species with the highest amount of toxins in their adult stage of life that are capable of causing these poisonings are poorly understood. Dusky grouper ( ) is a relevant fishing species and is part of the CTX food chain in the Canary Islands. This study developed an experimental model of dietary exposure featuring adult dusky groupers with two diets of tissue naturally contaminated with CTXs (amberjack and moray eel flesh) with two different potential toxicities; both groups were studied at different stages of exposure (4, 6, 10, 12, and 18 weeks). The results showed that this species did not show changes in its behavior due to the provided feeding, but the changes were recorded in biochemical parameters (mainly lipid and hepatic metabolism) that may respond to liver damage and alterations in the homeostasis of the fish; more research is needed to understand histopathological and cytotoxic changes.
