用青草直接喂鱼,其营养利用率低.如果把草打成草浆再喂鱼,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.其原因是;草浆中有很多与浮游生物大小相同的颗粒。可供滤食性和杂食性鱼类利用.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.除被大型浮游动物和底栖动物利用外.还能在细菌的作用下转化为浮游生物的营养元素,促进浮游生物的增殖.从而为鱼类提供丰富的天然饵料.怎样打浆用打浆机将水葫芦、水花生、水浮莲及一些陆生草类打成草浆.打浆时.加料要少量多次,草和水的比例要掌握好,尽量把草浆打得细一些.以增加草浆颗粒在水中悬浮的时间,提高草浆利用率.各种草在打浆前均需用清水冲洗干净,并用漂白粉溶液浸泡
The direct use of grass to feed the fish, its low utilization of nutrients .If the grass labeled as straw and then feed the fish, the nutritional utilization rate can be increased by more than 50%, but also play a dual role of feeding and fertilization. The reason is; There are many particles in the straw that are the same size as plankton. For feeding and omnivorous fish use, while the larger debris, was grass carp, bighead carp, head dwarf and other herbivorous fish feeding.Fresh fish fed the straw particles and juice.In addition to being large Zooplankton and zoobenthos, but also in the role of bacteria into the nutrients of plankton and promote the proliferation of plankton. So as to provide rich natural fish feed. How to beater with beater water hyacinth, water Peanuts, water lettuce and some terrestrial grass labeled as straw pulp. Beating when feeding a small amount of times, the ratio of grass and water to master, try to beat the straw pulp some to increase the straw particles in the water Suspended time, improve the utilization of straw. All kinds of grass before beating must be rinsed with water and soaked in bleach solution
