鱼鳖混养能促进生长,增加产量。原因如下:①鳖是用肺呼吸的爬行动物,必须经常由水底到水面交换气体,它上下往返活动,使水底溶氧得到交流。有利于鱼的生长和浮游生物的繁殖。②鳖在池底活动,促进池底腐殖质的分解还原,加速能量的循环。⑧鱼鳖混养投饵重点对象是鳖,其次是草鱼。鳖和草鱼排泄的粪便能培肥水质,以利繁殖较多的浮游生物供鲢、鳙食用,饵 Fish and turtle polyculture can promote growth and increase production. The reasons are as follows: ① turtle is a reptile breathing of the lungs, the gas must often exchange water from the bottom to the surface, it is up and down from the activities, the bottom dissolved oxygen to be exchanged. Is conducive to the growth of fish and plankton reproduction. ② turtles in the bottom of the pool to promote the decomposition of the bottom of the decomposition of humus, accelerate the energy cycle. ⑧ fish turtle polyculture feeding object is turtle, followed by grass carp. Turtle and grass carp excretion of manure can fertilize water quality, to facilitate the breeding of more plankton for silver carp, edible, bait
