Problems solved by technology

However, in recent years, due to environmental pollution and the abuse of fishery drugs and antibiotics, the meat quality and taste of fish have been greatly reduced.
[0005] Although the existing research has proposed the implementation of salty culture of bighead carp, the technical scheme is vague, and the use of microecological preparations is still required, and the effect of the culture is very unstable and the effect is not good.

Embodiment 1

[0049] In order to reduce the injury rate and mortality of bighead carp during the fishing process, the temperature should be kept between 8 and 25°C as much as possible during the whole breeding process of salted and thinned carp. Due to the large difference in monthly average temperature in different regions of the country, the months suitable for salty and slimming breeding are different in different regions. The most suitable months are April to September in Northeast China, March to June in North China, April to October in Northwest China, February to May in Southwest China, February to June in East China, and January to May in South China , can obtain stable and excellent breeding results.

[0050] Adult fish should choose individuals with no damage, no infection, no deformity, and strong physique, and their body weight should be greater than 2kg in principle.

[0051] Before putting the bighead carp into the pond for recuperation, firstly, do a sampling inspection of m...

Abstract

The invention relates to the technical field of bulk fresh water fish culture, and provides a salinization weight-reducing bighead carp culture method. Selected bighead carps are subjected to pond recuperation and salinization culture, and the bighead carps discharge vivotoxin while swimming by the aid of flowing water so as to remove redundant fat; the bighead carps with weight reduced are subjected to salinization culture with appropriate salinity, harvested bighead carps are good in meat quality, delicious and high in economic value, and cultured bighead carps are bright in body color, strong, free of muddy taste, less in fat and chemical residue, good in taste and high in quality.

Description

technical field [0001] The invention relates to the technical field of aquaculture of bulk freshwater fish, and provides a salty and slimming aquaculture of bighead carp [0002] method. Background technique [0003] bighead carp ( Aristichthysnobilis ) is also called bighead carp, silver carp, fat head fish, baotou fish, big head fish, black carp, etc., teleosts, Cyprinidae, Cyprinidae. It looks like silver carp, flat on the side, and is a kind of freshwater fish. The head is big and wide, and the length of the head is about 1 / 3 of the body length. The mouth is also wide and slightly upturned. [0004] The meat of bighead carp is white and tender, and the fish brain is rich in nutrients. It contains a kind of fish oil needed by the human body. The polyunsaturated fatty acid rich in fish oil is an essential nutrient for human beings, which can maintain, improve and improve brain functions. Fish The meat under the gills is transparent jelly, which is rich in collagen, whic...
