COMPARISON OF BROODSTOCK LIPID STORES IN FARMED AND WILD EUROPEAN EEL (Anguilla anguilla) IN LINK WITH REPRODUCTIVE PERFORMANCE

摘要

Reproduction of the European eel is a focus research area for a self-sustained aquaculture of this species. Among the numerous factors that could affect reproductive performances, the nutritional condition of broodstock fish is of particular importance in eel as feeding ceases concomitant with silvering in nature and in captivity at the transfer to saltwater prior to induction of maturation. Like many marine fish species, eel utilise stored lipid reserves during maturation of the ovaries highlightingthe importance of pre-spawning nutrition, in particular the role of liposoluble compounds.
