INDUCTION OF SPERMIATION, OVULATION AND SPAWNING IN ATLANTIC BLUEFIN TUNA (THUNNUS THYNNUS) USING GNRHA DELIVERY SYSTEMS

摘要

Fueled by the increasing demand for bluefin tuna for the sashimi-sushi market in Japan, Europe and the United States, in the last decade there has been a booming fattening industry developing around the Mediterranean coast. Tuna fattening is a "capture-based aquaculture", and involves the capture of wild fish and their culture in floating cages. The recent expansion of this industry is considered threatening to the wild population, and there is a great interest in developing broodstock management, spawning and larval rearing methods for bluefin tuna.
