Purse net high-efficient ecological cultivation method

Abstract

The invention relates to a purse seine cultivation method, in particular to a purse seine high-efficiency ecological cultivation method, which adopts a three-layer three-dimensional mixed cultivation method, wherein the upper layer water body cultivates silver carps; the middle layer water body cultivates Taihu whitefish or squaliobarbus curriculus first, and then cultivates catfish; and the lower layer water body cultivates hemibarbus maculatus bleeker, and leiocassis longirostris or pseudobagrus fulvidraco first, and then cultivates turtle. The method selects proper fish species and breeding density according to the eutrophication degree of the water body and the food habits and the life habits of fishes, does not put feedstuffs, baits or fertilizers into the water body in the whole cultivation process, makes full use of the water body natural resources, changes the waste into valuable and harmful into beneficial, and reduces the water body pollution, thus the cultivation cost of aquatic products is low, the quality of the aquatic products is high, and the economic benefit is good. The method solves the technical problems that most of the prior purse seine cultivation species mainly comprise the fishes which are cultivated with feedstuffs, cause water quality eutrophication to pollute the water body, and cause ecological balance disturbance.

Description

technical field [0001] The invention relates to a purse seine breeding method, in particular to a purse seine efficient ecological breeding method. Background technique [0002] Seine aquaculture is favored because of its simple and efficient fishery utilization method. At present, most of the domestic aquaculture species in peripheral nets are mainly carnivorous fish. During the breeding process, feed, bait or fertilizer are continuously put into the water body. The development of seine aquaculture is excessive. It will cause eutrophication of water quality and pollute water bodies, resulting in imbalance of ecological balance. Contents of the invention [0003] The method problem to be solved by the present invention is: to solve the technical problems of water quality eutrophication and ecological balance imbalance caused by the existing purse seine culture mainly based on food fish. The amount of feed, bait or fertilizer used in the whole breeding process is very smal...

Problems solved by technology

[0003] The method problem to be solved by the present invention is: to solve the technical problems of water quality eutrophication and ecological balance imbalance caused by the existing purse seine culture mainly based on food fish. The amount of feed, bait or fertilizer used in the whole breeding process is very small, which can make full use of the natural resources of the water body, turn waste into treasure, and turn harm into benefit, so as to reduce the cost of breeding, reduce water pollution, improve the quality of aquatic products, and increase economic benefits.
