Nutritional requirements of wreckfish are unknow so far and there are only a few references related to feeding habitats from commercial caught (Brick Peres & Haimovi, 2003) and feeding rates in captivity (Papandroulakis et al., 2004) . Recently some studies were done about composition of wild wreckfish (Roncarati et al.,2014, Linares et al., 2015). The optimum development of broodstock diets for wreckfish will be essential for the future of the aquaculture of this species. Dietary lipids and specially fatty acids play a critical role in the successful production of high quality gametes and eggs of marine fish (Izquierdo et al., 2001; Sargent et al., 2002). The aim of this work is collecting information about the influence of the feeding of wreckfish broodstock on oocytes composition with the aim of knowing the relationship of broodstock feeding on fecundity and spawn quality.
