青草直接喂鱼,其利用率低,如果将青草先打成草浆然后再投喂,其营养利用率可提高50%以上,而且还可起到投饵和施肥的双重作用。草浆中有很多浮游生物大小的颗粒,可供滤食和杂食性鱼类利用。而较大的碎片,则被草鱼、鳊鱼、团头鲂等草食性鱼类摄食。未被鱼类摄食的草浆颗粒及浆汁, Grass feeding directly to fish, its utilization rate is low, if the grass first labeled straw and then fed, the nutritional utilization rate can be increased by 50% or more, but also play a dual role of feeding and fertilization. There are a number of plankton-sized particles in the straw that can be used by both filter feeders and omnivorous fish. Larger fragments, however, are consumed by herbivorous fish such as grass carp, bighead carp and bighead carp. Strawberry pellets and juices that are not consumed by fish,
