最近,世界各国对虾养殖业的发展十分迅速,特别是台湾年产15000T,厄瓜多尔年产3万T,都远远超过日本。而且,这一爆发性的对虾养殖热,有进一步扩展到世界各国的倾向。在这样发展的对虾养殖业中,确保产卵及健壮的种苗来源是最重要的研究课题。日本对虾,虽然天然亲虾较易获得,种苗生产也相对稳定,但这在各国对虾养殖中还是较为棘手的问题,特别是斑节虾。对虾类的蚤状幼体期及糠虾幼体期的初期饵料一般用硅藻、绿藻等单细胞藻类及卤虫等浮游动物。但是保证经常供给大小相近且营养价稳定的浮游生物并不容易,所
Recently, the development of shrimp farming in various countries in the world has been very rapid. In particular, Taiwan has an annual output of 15,000 T and an annual output of 30,000 T in Ecuador, far exceeding that of Japan. Moreover, this outbreak of shrimp farming fever has a further tendency to extend to all countries in the world. In the shrimp farming industry so developed, ensuring spawning and robust seed sources is the most important research topic. Japanese shrimp, although easy to get natural broodstock, seed production is relatively stable, but this is still more difficult in the shrimp farming in various countries, especially the spotted shrimp. The shrimp species of fleas and juveniles during the early stage of shrimp feeding the general use of diatoms, green algae and other unicellular algae and brine shrimp and other zooplankton. However, it is not easy to ensure that plankton that are often supplied in similar sizes and with stable nutritional value are available
