卤虫早期幼体营养丰富,作为鱼、虾、蟹幼体的饵料,在水产育苗中已被广泛采用,但对其孵化所需盐度、pH及孵化时间意见不一。本文就这几个因子对卤虫孵化率的影响进行了试验总结。 试验用卤虫卵系采自河北省海兴的冬卵。卵取回后经漂洗、沉淀去杂质,在-28～—30℃速冻,存放于-18℃冷库中。用前取 Artemia early larvae are rich in nutrients and are widely used as feed for fish, shrimp and crabs in hatcheries for aquatic products, but they differ in their salinity, pH and hatching time required for hatching. In this paper, several factors on Artemia hatching rate were experimentally summarized. Artemia eggs were collected from winter eggs in Haixing, Hebei Province. The eggs were rinsed after retrieval, and precipitated to impurities, frozen at -28 ~ -30 ℃ and stored in -18 ℃ cold storage. Take before use
