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

Purse net high-efficient ecological cultivation method
Technical field
The present invention relates to the seining cultivation method, particularly a kind of purse net high-efficient ecological cultivation method.
Background technology
Seining cultivation because of its fishery utilize mode simple and direct, efficiently enjoy favor, at present, the seining cultivation kind is mostly based on food property fish both at home and abroad, breeding process constantly drops into feed, bait or fertilizer to water body, the seining cultivation development excessively, can cause the water quality eutrophication and polluted-water causes disturbed ecological balance.
Summary of the invention
The method problem that the present invention will solve is: solving existing is the technical problem that main seining cultivation causes water quality eutrophication, disturbed ecological balance with food property fish, the invention provides a kind of purse net high-efficient ecological cultivation method, it throws in feed, bait or fertilizer quantity seldom in whole breeding process, can make full use of the water body natural resources, turn waste into wealth, change evil and be benefit, reach the reduction aquaculture cost, reduce water pollution, improve the aquatic products quality, increase the purpose of economic benefit.
The present invention solves the method scheme that its method problem adopted: a kind of purse net high-efficient ecological cultivation method, and adopt three-layer stereo to raise together with, throw in flower silver carp in the water body of upper strata, the animals and plants that swim in the water body of mainly ingesting; Throw in Taihu Lake whitefish or Squaliobarbus curriculus in the water body of middle level, the wild fishes and shrimps in the water body of mainly ingesting are thrown in the silver xenocypris fish again, and the algae that adheres on the etting of ingesting and the foreign organic matter of bottom play water body " street cleaner's " effect; Throw in season youth fish, long river Catfish fish or yellow cartfish in lower floor's water body, throw in soft-shelled turtle again, zoobenthos such as the insect that mainly ingests, shell-fish.
For making full use of the water body natural resources, reduce aquaculture cost, reduce water pollution, improve the aquatic products quality, the injected volume of the flower silver carp in the water body of described upper strata is every mu and throws in 30~40 kilograms of the flower silver carps that specification is 10~20 tail/kilograms; The injected volume of fish is every mu of Taihu Lake whitefish 30~50 tails or 40~60 Squaliobarbus curriculus 30~50 tails that restrain of throwing in 10~15 centimetres in the water body of described middle level, throws in 10~15 centimetres silver xenocypris fish 80~120 tails again; The injected volume of fish is every mu of season youth fish 180~220 tails or long river Catfish fish 40~60 tails of 100~150 grams or yellow cartfish 80~120 tails of 8~12 centimetres of throwing in 8~10 centimetres in the described lower floor water body, throws in 30~50 of 100~200 young soft-shelled turtles that restrain again.
The invention has the beneficial effects as follows: purse net high-efficient ecological cultivation method of the present invention, according to the eutrophication degree of water body, feeding habits and the life habit of fish, select fingerling and suitable breeding density, the feed of throwing in whole breeding process, bait or fertilizer seldom make full use of the water body natural resources, turn waste into wealth, change evil for benefit, reduced water pollution, the aquaculture cost of aquatic products is low, aquatic products quality height, good in economic efficiency.
Embodiment
Embodiment 1:
Jiangsu Province fishes in Changzhou Wujin District Jia Ze town seining cultivation demonstration area, Gehu lake, village, and 300 mu of cultured areas are thrown in 10500 kilograms of the flower silver carps that specification is 10~20 tail/kilograms at the upper strata water body; In the water body of middle level, throw in about 12 centimetres Taihu Lake whitefish 12000 tails, throw in about 10 centimetres silver xenocypris fish 30000 tails; In lower floor's water body, throw in 8~10 centimetres season youth fish 60000 tails, 12000 of the young soft-shelled turtles of 100~200 grams.
Embodiment 2:
Seining cultivation demonstration area, Gehu lake, Tang Kou village, Changzhou Wujin District Niu Tang town, Jiangsu Province, 200 mu of cultured areas are thrown in 7000 kilograms of the flower silver carps that specification is 10~20 tail/kilograms at the upper strata water body; In the water body of middle level, throw in Squaliobarbus curriculus 8000 tails about 50 grams, throw in about 10 centimetres silver xenocypris fish 20000 tails; In lower floor's water body, throw in 8~10 centimetres yellow cartfish 40000 tails, 8000 of the young soft-shelled turtles of 100~200 grams.
Embodiment 3:
Seining cultivation demonstration area, bridge Gehu lake, Changzhou Wujin District stockaded village, Jiangsu Province, 100 mu of cultured areas are thrown in 3500 kilograms of the flower silver carps that specification is 10~20 tail/kilograms at the upper strata water body; In the water body of middle level, throw in about 12 centimetres Taihu Lake whitefish 4000 tails, throw in about 10 centimetres silver xenocypris fish 10000 tails; In lower floor's water body, throw in long river Catfish fish 5000 tails about 100~150 grams, 4000 of the young soft-shelled turtles of 100~200 grams.
