山口县近海栽培渔业中心在陆上水池中,人工养殖的一尾红鳍东方鲀在自然条件下成功地产卵约1.1kg(80万粒卵),为人工育苗提供了保证。人工养殖的红鳍东方鲀大量产卵在日本还属首次。随着野生资源的减少,自然苗种缺乏,1986年日本着手进行罕见的陆上水池人工养殖研究。对水温、光照、饵料等进行全面管

In the land-based pond, a man-made red-winged Tung Fongi 成 succeeded in laying eggs at a density of about 1.1 kg (800,000 eggs) under natural conditions, which provided a guarantee for artificial breeding. It is also the first time that a large number of red-tipped Oriental flies have been spawned in Japan. With the reduction of wild resources, the lack of natural seedlings, in 1986 Japan started a rare study of the artificial breeding of onshore water. On the water temperature, light, bait and other comprehensive management
