What role does ecological fishery play in the sustainable development of fishery?

Eco-fishery is a kind of breeding mode based on the principle of complementary between breeding animals and other organisms, using the land and water material circulation system and taking corresponding technical and management measures to maintain ecological balance and improve breeding efficiency. Developing ecological fishery can make full use of local resources, recycle wastes, save energy, improve comprehensive ecological benefits and realize the sustainable development of fishery. Eco-fishery is an effective way to build a resource-saving and environment-friendly fishery, an important part of developing rural circular economy and the development direction of modern fishery.

The main functions of ecological fishery:

(1) The aquaculture structure has been optimized and adjusted.

According to the principle of ecology, fully popularize the 80∶20 mode of aquaculture, highlight the main varieties, and properly match with other famous aquatic products such as freshwater shrimp, river crab, snakehead, soft-shelled turtle and yellow catfish to realize complementary advantages, improve quality and benefit.

(2) The natural ecological environment of the waters has been effectively protected.

According to the co-evolution principle of food chain and biology and environment, the regulation of water ecological environment is highlighted. Take biological and physical measures to control water quality and continuously improve the ecological environment quality of fishery waters. For example, in the ecological culture of river crabs, by planting aquatic plants, transplanting snails, properly interplanting silver carp and freshwater shrimp, combined with mechanical oxygenation and water injection, not only a good ecological environment is created in the waters, but also the utilization rate of fishery resources is effectively improved.

(3) The leisure and sightseeing fishery has made great progress.

On the basis of actively building nature reserves and wetland ecological protection zones, efforts should be made to develop and build sightseeing and leisure fishery belts, so as to organically unify the development of fishery resources and the protection of ecological environment, and form a sightseeing and leisure ecological fishery base integrating fishery production, sightseeing, catering and entertainment.
