ャイト八夕の人工種苗生産技術開発と養殖技術開発

摘要

Okinawa prefecture developed seedling production and aquaculture technique of the Malabar Grouper from 1985. Okinawa succeeded in the mass production of the Malabar Grouper seedling in 1997, and in the early production of the Malabar Grouper seedling using the seawater under the ground in 2010. The Malabar Grouper aquaculture is run with the fish preserve of the sea and a land water tank. The annual amount of production of the Malabar Grouper aquaculture reaches 90t, and an annual production value is 100 million yen. In the Malabar Grouper aquaculture in the sea, the death of the seedling due to parasite becomes the management problem. By the Malabar Grouper aquaculture using the land water tank, we develops the cultured method using the semiclosure circulation-type land cultured system.
