Problems solved by technology

However, in recent years, due to the massive fertilization of cages, pens, and seine aquaculture on large water surfaces, the water quality has been seriously polluted. destroy
[0003] In addition, the overall economic benefits of large water surface farming are low, so increasing production is also one of the ways to improve economic benefits

Abstract

The invention discloses a large-water surface water tank type intensive culturing method. Culture is conducted in independent culturing environment formed water tanks or water channels. Fishes are cultured in a large lake with net cages sleeved in the water tank; characteristics of excellent water quality of a large water surface and inadequate utilization of resource are fully utilized to output of the large water surface can be increased by 15 to 50 kg / mu and 30% of efficiency can be improved; by the use of the culturing method, diseases can be prevented, fishes can be easily caught, bait casting amount can be controlled, fodder use can be reduced, stable water temperature and quality can be achieved and influence to the ecological environment can be reduced; bait utilization rate can be effectively improved; effects on water quality of the whole large lake surface can be reduced; pollution of water quality of each independent water tank or water channel can be avoided; and besides, survival competition between the cultured fishes and local fish species can be avoided and damage to fish genetic resource can be prevented.

Description

technical field [0001] The invention relates to the field of breeding technology, in particular to a large water surface tank type intensive breeding method. Background technique [0002] Large water surface farming refers to a method of cultivating aquatic products using reservoirs, lakes, rivers, etc. In addition to the extensive type of breeding in the early stage, it also includes intensive farming models such as "net cages, net pens, and seine nets". Intensive farming such as nets, pens, and purse seines is the application of techniques such as artificial baiting and fertilization, which greatly improves the products. However, in recent years, due to the massive fertilization of cages, pens, and seine aquaculture on large water surfaces, the water quality has been seriously polluted. destroy. [0003] In addition, the overall economic benefits of aquaculture in large water surfaces are low, so increasing production is also one of the ways to improve economic benefits....
