Problems solved by technology

The taste of bighead carp fed with artificial concentrated feed is worse than that of natural bighead carp, the meat quality is loose, and the umami taste is reduced; while the growth cycle of bighead carp fed with pure green feed is longer, which cannot meet the market demand
When bighead carp is raised in monoculture, the species is single, the pond space and bait are not fully utilized, and the benefit is low. When the bighead carp is cultured in a mixed culture, it is necessary to choose a reasonable species and quantity, which is in line with the ecological cycle of the pond.

Abstract

The invention provides a method for ecological breeding of bighead. According to the method, biological fermented feed and green grass feed are adopted, the water quality is adjusted by adopting a simulation ecosystem polyculture mode, Chinese herbal medicines are adopted for fish disease control, no chemical is added in the breeding process, and finished fish is fresh, tender and smooth and has no sludge taste and is green and pollution-free excellent aquatic product. The fermented feed, the green grass feed and the Chinese herbal medicines are adopted, the raw material sources are extensive, and the breeding cost is low.

Description

technical field [0001] The invention relates to a freshwater fish breeding technology, in particular to an ecological breeding method for bighead carp. Background technique [0002] Bighead carp (scientific name: Aristichthys nobilis) is also called silver carp, fat head fish, Baotou fish, big head carp, black carp, black carp, and male carp. It is a type of freshwater fish. Known as "water scavenger", it is one of the four major fishes in China. Bighead carp is a fish with high protein, low fat and low cholesterol. Every 100 grams of bighead carp contains 15.3 grams of protein and 0.9 grams of fat. In addition, bighead carp also contains nutrients such as vitamin B2, vitamin C, calcium, phosphorus, and iron. Bighead carp has a protective effect on the cardiovascular system. Rich in phospholipids and memory-improving pituitary gland vasopressin, especially in the brain, it is often eaten to warm the stomach, eliminate dizziness, improve IQ, help memory, delay aging, and ...
