Embodiment 1

[0063] see Figure 1-4 , a kind of method for raising fish and fishing for ecological circulation type fishery, comprising the following steps:

[0064] S1. Water area selection: select water areas suitable for fish growth as fish breeding areas and alternative areas for fish breeding;

[0065] S2. Set up fish blocking facilities: set up fish blocking facilities around the fish enrichment area and the optional area for increasing fish, and evenly arrange artificial fish reefs in the fish increasing area and the optional area for increasing fish;

[0066] S3. Cultivation of fish species: artificially cultivate fish species in temporary breeding ponds;

[0067] S4, fish species out of the pond: take out the artificially cultivated fish species in the holding pond, and transport them to the fish enhancement area;

[0068] S5, water increase: spread seedlings in fish increase area and increase selection area;

[0069] S6. Fishing back: Fishing is carried out on a regular basis....

Abstract

The invention discloses a fish breeding and catching method for ecological circulation type fishery, and belongs to the field of fishery; the fish breeding and catching method for ecological circulation type fishery comprises the steps, for example: selecting water areas, arranging fish blocking facilities, cultivating fingerlings, discharging the fingerlings out of ponds, breeding the fingerlingson water and recapturing the bred fingerlings. The survival rate of the fingerlings can be effectively increased after the fingerlings leave the ponds and enter the field environment; the fishery resources can be restored, the fish germplasm resources can be protected, and stable income is created for fishermen; the method has the advantage of simultaneous protection and utilization. According tothe method, the degraded fish resources of the lakes can be updated, the fish population structures are enriched, the total amount of the fish resources is increased, the sustainable utilization of the commodity fish resources is guaranteed, the eutrophication level of the lakes is reduced, and the ecological circular development of fishery is facilitated.

Description

technical field [0001] The invention relates to the technical field of fish farming, and more specifically relates to a method for increasing fish breeding and fishing for ecological cycle fishery. Background technique [0002] Fishery refers to the social production sector that catches and breeds fish and other aquatic animals and aquatic plants such as seaweed to obtain aquatic products. Generally divided into marine fisheries, freshwater fisheries. Fishery can provide food and industrial raw materials for people's livelihood and national construction. The social production sector that develops and utilizes water areas, collects, fishes, and artificially breeds various aquatic animals and plants of economic value to obtain aquatic products. It is an important part of broad agriculture. According to the water area, it can be divided into marine fishery and freshwater fishery; according to the production characteristics, it can be divided into breeding industry and fishin...
