dc.description.abstractThe present work describes the evolution of Seriolla dumerilli stock in the Instituto Canario de Ciencias Marinas from year 2006 to 2009. Nine sub adults of kingfish were captured by local fisherman in the south coast of Gran Canaria in may 2006, fish were transported in a truck and transferred to on land facilities. Adaptation to tanks and inert food was successfully carried out one month after the capture. After 3 year kept in captivity 100% survival was obtained. Initial fish weight (1,66kg), was increased over to 8,0 kg nowadays. 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 ovarian biopsy. Oocites over 500 microns were observed in year 2008 in one of the females with an average weight of 3,8kg. In year 2009, mature fish were observed, but natural spawn was unsuccessful, however the use of hormonal injection (LHRH) results in two successful spawn with around 0,5 millions eggs (99% unfertilized eggs).en_US
