Carp feeding method of circulating water system

Abstract

The invention discloses a carp feeding method of a circulating water system. Feeding is carried out according to a nutrition metabolism rule under the influence of a water flow speed and the characteristics of the circulating water system, according to the physiological rule of carps under the action of water flow, the carps continuously move under stimulation of the water flow, the flow speed isincreased, the energy requirement of the carps is gradually enhanced, as time goes on, the activity of various metabolic enzymes in the carps is enhanced, the absorption function of the intestinal tracts of the carps is improved, the feed conversion efficiency is improved, initial special feed and middle and later special feed are prepared respectively, the feed utilization efficiency is improved,and purposes of increasing the growth speed of the carps, ensuring the stability of water quality and improving the breeding benefit are achieved.

Description

technical field [0001] The invention relates to the technical field of carp breeding, in particular to a method for feeding carp in a circulating water system. Background technique [0002] Aquatic products are an important source of Chinese national food. For example, in 2018, the total output of aquatic products in the country reached 64.58 million tons, of which the output of aquaculture products was 49.91 million tons, accounting for 77% of the total output, with an average of 46 kg / person, ranking first in the world for 29 consecutive years. Among them, carp has the longest farming history and one of the highest yields in my country. In 2016, the carp has exceeded 3.4 million tons, and there is a huge market. [0003] The rapid development of my country's aquaculture industry has gradually become an important agricultural industry to solve food shortages and ensure food safety. direction of development". Traditional aquaculture models, mainly pond aquaculture and net ...

Problems solved by technology

[0005] It is worth noting that there is still a lack of high-efficiency special feeds and feeding methods for recirculating aquaculture. In production practice, most farmers use ordinary pond culture methods, using conventional feed formulas and traditional feeding methods, while ignoring the importance of recirculating aquaculture. The impact of the aquaculture system is different from the traditional large water surface pond aquaculture method. In the process of recirculating aquaculture, residual bait is prone to cause pressure on the circulating water filtration system, resulting in poor water quality.
