利用苇地养鱼省时、省力、收益高,值得推广,今介绍如下: (1)芦苇为挺水植物,鱼为水生动物,把二者人为地置于同一生态环境中,通过苇地的自净作用使水质得以净化,使鱼的生活环境得以改善,鱼的发病率低。 (2)苇地中的大量杂草、昆虫、底栖动物及丰富的浮游生物,为草食性鱼类、鲤鲫等底层鱼类及鲢鳙鱼提供了充足的优质饵料。 (3)鱼可吃掉与芦苇争肥的杂草和危害芦苇的昆虫,疏松土壤;鱼的粪便又可为芦苇施肥,促进其生长。
The use of reed aquaculture saves time, effort, high returns, it is worth promoting, this is introduced as follows: (1) reeds as emergent plants, fish for aquatic animals, the two artificially placed in the same ecological environment through the reed Self-purification to purify the water quality, fish living environment can be improved, the incidence of fish is low. (2) The large amount of weeds, insects, zoobenthos and abundant plankton in the reed soil provide plenty of high-quality bait for bottom fish such as herbivorous fish, carp crucian carp and silver carp and bighead carp. (3) The fish can eat the weeds competing with the reeds and the insects that harm the reeds, loosen the soil; and the excrement of the fish can also fertilize the reeds and promote their growth.
