FAO, 2012 and 2014, raises the importance of reproduction in fish farming. The increase in world fish production is due to the intensification of farming systems, which means producing large numbers of fingerlings for growth and fattening (Orozco, 2012). In the last decade, the influence of nutrition on reproduction has been investigated, many authors suggest that nutrients such as polyunsaturated fatty acids (PUFA) affect reproduction (Tocher, 2010, Turchini et al., 2011). Several studies have focused on the establishment of nutritional requirements for reproductive success, however, few determinations on PUFA, have been made (Pohlenz et al., 2014). Consequently, several studies have used omics tools (Rodrígues et al., 2012), to integrate environmental and genetic information in the fish brain for transduction into neuronal signals through biochemical and physiological mechanisms, capable of modulating the hormonal secretion involved in fish reproduction (Wing-Keong and Wang, 2011, Norambuena et al., 2012). These biochemical processes in fish need to be elucidated to improve farming systems, increase production levels, meet demand and achieve impressive advances in the field of scientific knowledge.
