轮虫(Rotifera)是线形动物门轮虫纲的一类动物,个体很小,体长一般在100～50O微米之间,少数种类可达2毫米。几乎所有水域中都有轮虫的分布,但相比之下,淡水中多,海洋中少。目前,随着水产养殖事业的发展,轮虫作为鱼虾等水产动物的开口饵料日益受到人们的重视。研究轮虫、开发轮虫资源已成为水产养殖业的重要课题。 Rotifera (Rotifera) is a class of linear animal rotiformes a class of animals, small individuals, body length is generally between 100 ~ 50O microns, a few species up to 2 mm. There is a distribution of rotifers in almost all waters, but by contrast, freshwater is much more and less in the ocean. At present, with the development of aquaculture, rotifers are gaining more and more attention as bait for aquatic animals such as fish and shrimp. Studying rotifers and developing rotifer resources has become an important topic in aquaculture.
