牙鲆是近海冷温性底层肉食性经济鱼类,具有生长迅速、繁殖力强、洄游性小、回归性强、肉质肥美等优点,是优良的近岸养殖、增殖品种。牙鲆在日本被列为近期大量生产苗种的高级海产鱼类,在海洋牧场计划中也被列为重要的增殖对象。为了促进我国海水鱼增养殖事业的发展,1990年5月我们捕获天然亲鱼,人工催产、受精、自然产卵,培育出2.5～4.1cm苗种52635尾,业已通过省内外专家的验收。 Paralichthys olivaceus is a coastal carnivorous economically fish, with rapid growth, strong reproductive capacity, small migratory, strong regression, succulent meat and other advantages, is an excellent coastal culture and proliferation of species. Paralichthys olivaceus is listed as a high-quality marine fish that has recently produced large quantities of seed in Japan and has also been listed as an important proliferation target in the marine ranch program. In order to promote the development of marine aquaculture in our country, in May 1990, we captured natural broodstock, artificially induced births, fertilized and spawned naturally. We developed 52,635 seedlings of 2.5-4.1cm and have passed the inspection of experts both inside and outside our province.
