Method for realizing ecological aquaculture by regulating water quality of high-yield aquaculture pond

Abstract

The invention discloses a method for realizing ecological aquaculture method by regulating the water quality of a high-yield aquaculture pond. The method integrates micropore oxygen increasing technology, a fish and vegetable co-existing technology and a water quality regulation micro-ecological agent using technology, so that the water quality of the high-yield aquaculture pond can be improved substantially, the water transparency can be improved, total ammonia nitrogen, nitrite nitrogen, total phosphorus and total nitrogen in water can be reduced, the pH of water can be stabilized, the density of blue algae, green algae and euglena which are harmful to aquaculture can be reduced obviously, diatom, dinoflagellate and cryptomonad which can serve as bait are not influenced obviously, an experimental pond is relatively stable in the aspect of zooplankton, accordingly, micro-ecological balance of the aquaculture water can be improved and stabilized, the yield can be increased, the earnings can be increased for a farmer, and the method can be widely applied to ecological breeding of various types of aquatic animals and plants.

Description

Technical field [0001] The invention belongs to the field of aquaculture, and specifically relates to an aquatic breeding method by regulating the water quality of a high-yield breeding pond. Background technique [0002] Aquaculture is the production activity of breeding, cultivating and harvesting aquatic animals and plants under artificial control. It generally includes the whole process of growing aquatic products from seedlings under artificial feeding management. There are extensive, intensive and high-density intensive aquaculture methods. In the world, aquaculture is most developed in some Asian countries, mainly China, Japan, India and Southeast Asian countries. In the early 1980s, the total production of fish, shellfish, shrimp, crabs and other aquatic products in the world was about 6 million tons, of which 66% was freshwater aquaculture production, and the rest was marine aquaculture production. The production of Asian countries (China accounts for half of them) ac...

AI Technical Summary

Problems solved by technology

However, frequent weather changes, reduced seedling quality, high breeding density, abuse of feed and fish medicine, and man-made vicious pond drainage have exacerbated the deterioration of the water environment of the breeding pond.
