日本的海洋渔业,因受200海里经济水域的影响大幅度减产后,刺激了增养殖业的迅猛发展。现在全国37个道府县设置了栽培渔业中心,已经开发了70余种鱼类和甲壳类的苗种生产技术。苗种生产,以往都广泛使用活饵料(轮虫、卤虫等浮游动物)或鱼糜等生鲜饵料,但活饵料的培养,很容易受到气象等因素的影响,难以得到数量稳定的培养物,所以对苗种生产往往成为限制因素。这就急需开发能 Japan’s marine fisheries, stimulated by the rapid economic growth of aquaculture, have been stimulated by the dramatic reduction in the economic waters of 200 nautical miles. Now 37 prefectures in the country have set up cultivation and fishery centers and more than 70 species of fish and crustacean seed production technologies have been developed. Seed production, the past are widely used live feed (rotifers, Artemia and other zooplankton) or surimi and other fresh food, but the live food culture, it is susceptible to weather and other factors, it is difficult to obtain a stable culture , So the production of seed is often a limiting factor. This urgently needs to be developed
