Problems solved by technology

Under intensive farming conditions, carp eat artificial compound feed and grow rapidly, but at the same time, their meat quality becomes looser and their flavor worsens compared with wild individuals

Embodiment Construction

[0006] The invention changes the carp meat quality through the feed. The carp is first fed with the compound feed according to the normal breeding method. When the carp reaches a body weight of 250-500 grams, stop feeding the carp with the compound feed. Feed compound feed instead of soaking soft broad beans; if the market size of carp is expected to be about 1000 grams, stop feeding compound feed when the body weight is 500 grams and use soaking soft broad beans instead; if the broad beans used are large, it is difficult for carp to swallow whole grains , then feed with soaked and crushed broad beans, which generally need to be soaked for 24 hours until the broad beans just germinate (commonly known as laughing sprouts); during the breeding period, the daily feeding amount of soaked broad beans is 3% of the body weight of the fish, and the water temperature is 18 ℃~30℃, pH value 6.5~8.5, dissolved oxygen in water > 3.0mg / L, among them, dissolved oxygen in water must be greater...

Abstract

A culture method for improving the meat quality of carps relates to fish culture, and the purpose of the invention is to culture carps with special meat quality by changing feeding. The technical scheme of the invention supplies compound feed according to the normal culture method, and is characterized in that: when carps are cultured to be 250g to 500g, compound feed supply is stopped, and macerated horsebeans are supplied; during culture, the amount of supplied feed per day is about 3 percent of the body weight of the carp, the water temperature is 18 DEG C to 30 DEG C, the pH value is 6.5 to 8.5, the dissolved oxygen is greater than 3.0mg / L in water, and needs to be greater than 5.0mg / L in water after more than 16 hours within continuous 24 hours, obvious oil slick or floating foam cannot appear on the water surface, the carps are fed with the macerated horsebeans for 3 months, and continue to be fed with the macerated horsebeans before being fished, the carps are fished when the body weight of the carps is doubled, and at the moment, the fished carps have special meat quality.

Description

technical field [0001] The invention relates to fish farming, especially carp with special meat quality. Background technique [0002] Carp (Cyprinus carpio) belongs to Cyprinidae and Cyprinidae, and is the most important freshwater aquaculture species in the world. In my country, carp is also a widely aquaculture fish species, and its aquaculture output is second only to grass carp. Under intensive farming conditions, carp eat artificial compound feed and grow rapidly, but at the same time, their meat quality becomes looser and their flavor becomes poorer than that of wild individuals. In this context, the quest to improve the muscle quality of farmed fish, including carp, has particular significance. Contents of the invention [0003] The purpose of the invention is to breed carp with special meat quality by changing the feed. [0004] The technical scheme of the present invention is to throw and feed compound feed according to the normal breeding method, and it is cha...
