传统的水产养殖育苗生产主要是使用微藻、轮虫和卤虫幼体等活饵。然而 ,活饵在生产管理上易受大气等环境因素的影响 ,其产量和质量都难以控制。此外 ,活饵的培养需要大规模的基建投资和占用大量空间 ,以致活饵料的生产成本高昂 ,这些都不利于水产育苗。因此近20年来水产学家
The traditional aquaculture breeding production mainly uses live bait such as microalgae, rotifers and Artemia larvae. However, live bait is easily affected by environmental factors such as the atmosphere in production management, and its yield and quality are hard to control. In addition, the cultivation of live bait requires large-scale capital investment and takes up a lot of space, so that the production cost of live bait is very high, which is unfavorable to aquaculture. So for nearly 20 years aquatic scientists
