Cobia is known as sea bream, bamboo five, sea grass, sea bass. It is widely distributed in the Pacific Ocean, Indian Ocean, and the Southwest Pacific, and north to the East China Sea and the Yellow Sea. It is not found only in the eastern Pacific Ocean. Cobia has a long round body, flat and wide head, front mouth, nearly horizontal and broad, dark brown body back, followed by a clear silver longitudinal belt, abdomen pale. Dorsal fins are short, hard and spiny, with anatomical fins with 2 to 3 weak spines. When the caudal fins are rounded, the adult caudal fins are semilunar. The general body length is up to 2 meters and weighs 50 kilograms. Egg buoyancy. Often caught off the continental shelf near the sea, often eggs parasitic on it, with crustaceans as the main food.
The fish was successfully nursed in Taiwan and was ready for mass production. 30 days after artificial hatching, the total length of cobia fry can reach 6 cm. Farming can be up to 1 to 2 kilograms for six months, 3 to 5 kilograms for 1 year, and 10 kilograms for 2 years. During the cultivation process, the caudal fins were changed in shape. At 130 cm, the caudal fins were pointed and tailed, and the 180 cm caudal fins were slightly truncated. Above 300 cm, the caudal fins were gradually deep-edged and the upper leaves were slightly longer than the lower leaves. During the breeding process, the larvae and fry are sized to separate them from each other in order to avoid mutual food.
