Abstract: The almaco jack Seriola rivoliana belongs to the Carangidae family of fishes. These species are an important resource for recreational and commercial fisheries worldwide. Among other attributes, almaco jack has being identified as potentially aquaculture species due to their fast growth, excellent flesh quality and significant market opportunities internationally. The present work describes the establishment of broodstock of Seriola rivoliana in the Instituto Canario de Ciencias Marinas from year 2006 to 2009 and subsequent maturation and spawning. Twenty sub adults were captured by local fisherman in the South coast of Gran Canaria in may 2006. Adaptation to culture conditions in tanks and inert food was successfully carried out just after one moth of capture. Initial fish weight (1,76± 0,25kg), was increased to 6,0±1,1kg in july 2009. Every year fish were sampled to determine individual growth in weight and size. In addition, the evolution of its sexual maturity state was established by gonadal biopsy. In July 2009, the use of hormonal injection (LHRH) results in two successful spawns with 42% of viable eggs.
