池塘内循环流水槽模式
本质上是露天大塘养殖模式的高级版,也是一种集约化养殖模式。注:在大塘的一侧,选定池塘总面积的2-3%,最多不超过5%的区域,为流水槽的建设面积,将主养鱼集中到流水槽内投铒饲喂,用罗茨鼓风机进行充氧、推水流动,设有投料机对每个养殖槽进行投铒,残饵粪便经过集污区时沉淀一部分,其余小颗粒粪随水流进入外塘净化区。大塘95%以上的水面用于水质净化,然后再次流入养殖槽内,如此往复循环。
Essentially, it is an advanced version of open-air pond farming mode, and also an intensive farming mode. Note: On the side of the pond, 2-3% of the total area of the pond is selected, and the maximum area is not more than 5%. For the construction area of the flume, the main fish are concentrated in the flume and fed with Erbium. Roots blower is used to aerate and push water. A feeder is installed to carry out Erbium in each aquaculture tank, and the remnant feces are deposited when passing through the sewage collection area. In part, the remaining small particles of feces enter the purification zone of the outer pond along with the flow of water. More than 95% of the water surface of the pond is used for water purification, and then it flows into the aquaculture tank again, so that it can be reciprocated.
