近年来,海产鱼的苗种生产飞速发展,相应,饵料生物,如轮虫的需要量也不断增加。但是,轮虫的生产很容易受天气情况左右,要做到固定化供给是很困难的。日本宫崎县水产试验场田中等人研究认为,可用冷冻轮虫代替活轮虫做苗种鱼饵料。轮虫作为饵料生物在营养学上的重要性就是它含有ω_3高度不饱和脂肪酸(HUFA)。如果用油脂酵母和小球藻作为轮虫饵料,轮虫的ω_3HUFA的含量就会增高。可是,把富含ω_3HUFA的轮虫进行长期冷冻保存,
In recent years, the rapid development of the production of marine fish seedlings, the corresponding food organisms, such as rotifers also increased the demand. However, rotifer production is easily affected by weather conditions and it is difficult to achieve a fixed supply. Miyazaki Prefecture, Miyazaki Prefecture Fisheries Experimental Field Tanaka et al. Studies suggest that frozen rotifers can be used instead of live rotifers do seed fish bait. The nutritional importance of rotifers as bait organisms is that they contain omega-3 highly unsaturated fatty acids (HUFA). If the fat yeast and chlorella as rotifer bait, rotifers of ω_3HUFA content will increase. However, long-term cryopreservation of rotifers rich in ω_3HUFA,
