Water tank type high-density micro-running water mandarin fish culture method

Abstract

The invention relates to a water tank type high-density micro-running water mandarin fish culture method, and belongs to the technical field of freshwater economic aquatic product culture. The water tank type high-density micro-running water mandarin fish culture method includes constructing running water tanks, allowing running water at the front and rear ends of the running water tanks to be smooth and keeping micro-running water states; arranging the insides of the running water tanks to be in water body stereoscopic oxygenation modes; arranging ecological wetland conservation regions on the peripheries of the running water tanks and cultivating diversified aquatic plants or aquatic weed floating beds. Fish blocking isolation fences are arranged at water inlet ends and drain ends of therunning water tanks. The water tank type high-density micro-running water mandarin fish culture method has the advantages that current diversified efficient facilities, equipment and technologies arecombined and used with one another, water body stereoscopic oxygenation can be formed by the aid of diversified oxygenation technical measures, micro-running water culture can be implemented, the excellent water quality of water bodies in culture regions always can be kept, the excellent foundation can be laid for high-density efficient culture, and the culture density and the yield per unit of the water tank type high-density micro-running water mandarin fish culture method are at least 5 times or even higher than 5 times the culture density and the yield per unit of existing traditional culture modes; the matched bait fish and running water tank culture regions are connected with one another side by side, accordingly, feeding and domestication management can be facilitated, the management efficiency can be greatly improved, the cost can be reduced, and the benefits can be increased; self-purification and restoration can be carried out on tail water discharged from the culture regions by the wetland ecological conservation regions, and accordingly zero-discharge pollution-free water circulating culture can be implemented.

Description

technical field [0001] The invention relates to a method for aquaculture of mandarin fish in a tank type high-density micro-flow water, and belongs to the technical field of freshwater economic aquatic product cultivation. Background technique [0002] Mandarin fish belongs to Perciformes, Fataceae fish, is a ferocious carnivorous fish, and feeds on live bait fish and shrimps all its life. It is a treasure among freshwater fish in my country. And other characteristics, has always been known as rare varieties. With the improvement of artificial breeding and breeding technology, the artificial breeding of mandarin fish is gradually becoming large-scale. However, due to the ecological characteristics of mandarin fish, its breeding technology is relatively difficult. The previous farming technology was relatively single, and most of the farming models were pond farming and nesting. The monocultivation and intensive cultivation of the species have also become bottlenecks restric...

Problems solved by technology

However, due to the ecological characteristics of mandarin fish, its breeding technology is relatively difficult. The previous farming technology was relatively single, and most of the farming models were pond farming and nesting. The single-culture and intensive-culture have also become bottlenecks restricting the further development of the aquaculture industry due to problems such as bait matching, domestication effect and diseases.
