Problems solved by technology

The system is composed of reservoirs, primary or secondary purification pools, and breeding pools. It adopts ectopic ecological restoration technical measures to alleviate the impact of aquaculture production on the external environment to a certain extent, but reduces Waste, the removal efficiency is limited after all
At the same time, because it is necessary to sacrifice part of the breeding area to purify the water quality, most farmers are unwilling to apply this technical model

Embodiment Construction

[0025] The present invention will be further described below in combination with specific embodiments.

[0026] The general layout of the present invention is easy to be arranged along the east-west or north-south direction according to the regional climate and the characteristics of the pond. The area ratio of the flowing water culture area, primary utilization area, benthos purification area and plant purification area in the four areas of the big pond is 1.5:10: 18.5:70. Intensive fish farming in the water tank. Free-range fish can be raised in large ponds. Among them, the ratio of food-eating fish and filter-feeding fish is about 80:20. The food-eating fish are mainly grass carp or herring. Since the water tank is located in the flowing water aquaculture area, The purpose of intensive fish farming can be achieved, and the economic benefits of the entire pond can be realized by using only a small area, and at the same time, the spreading area of ​​residual bait and feces can...

Abstract

The invention relates to an aquaculture technology, in particular to a pond circulating running water four-level ecological planting and breeding method. The problem that water in an existing pond eutrophicates is solved. As a big pond is divided into a running water culture region, a primary utilization region, a plant purifying region and a benthonic animal purifying region, residual bait and feces are collected in a centralized mode, water is purified through an biologic chain and prevented from eutrophicating, and meanwhile economic benefits can be increased.

Description

technical field [0001] The invention relates to an aquaculture technology, in particular to a four-stage ecological planting and breeding method with circulating water in ponds. Background technique [0002] At present, the average yield per mu of intensive culture ponds is more than 1000 kg, and there are not a few more than 1500 kg. The main means of maintaining such a high yield is the large-scale use of compound feed, large-scale water changes and the use of fishing machinery. Under normal circumstances, the bait coefficient is about 2.5, the water consumption per ton of fish is about 4,000 tons, and the power per mu is about 0.7 kilowatts. And 70-80% of the feed is discharged into the environment in the form of dissolved and particulate matter. According to the principle of energy transfer, that is to say, about 1000 kg of N, P, CO2 and other organic substances per mu of breeding water are lost to the pond environment. middle. In order to maintain its normal operatio...
