随着对虾人工育苗的发展,对虾幼体饵料已成为人工育苗的关键,近年来,由于卤虫卵供应不足,价格上涨,且质量每况愈下导至育苗成本不断增加。国内外对对虾幼体的饵料进行了大量的研究,并成功地应用到生产当中的有微型胶囊饵料、粉状微颗粒饵料,但据我们的使用,人工配合微型饵料质量不稳定,在水中悬浮时间短溶散太快,使育苗水质严重污染,造成危害。1988年在卤虫卵价格上涨而孵化率极低(2～10%)的情况下,我们决定不使用卤虫育苗。在1500m~3的育苗水体中进行了以蛤肉代替卤虫幼体做为对
With the development of artificial breeding of prawn, prawn larvae feed has become the key to artificial breeding. In recent years, due to insufficient supply of brine shrimp, the price has risen, and the quality has deteriorated, leading to the increasing cost of nursery. At home and abroad, a large amount of researches have been done on the feed of shrimp larvae, and have been successfully applied to the production of micro-capsule bait and powdery micro-particle bait, but according to our use, the artificial bait with artificial quality is unstable, suspended in water for a long time Short dissolution is too fast, so serious water pollution nurturing, causing harm. In 1988, when the price of Artemia increased and the hatching rate was very low (2 ~ 10%), we decided not to use Artemia. In 1500m ~ 3 nursery water body to clam meat instead of Artemia larvae as a pair
