Ecological breeding method for grass carps

Abstract

The invention provides an ecological breeding method for grass carps. Natural pollution-free mountain spring water is adopted as a water source, biologically fermented feeds and grass feeds are adopted, an ecological system simulation mixed breeding mode is adopted for regulating the water quality, Chinese herbal medicinal preparations are used for preventing and controlling fish diseases, and the addition of any chemical in a breeding process is avoided. Therefore, finished product fish is fresh, tender, smooth and free of silt smell, and is an environment-friendly, pollution-free and high-quality aquatic product.

Description

[0001] technical field [0002] The invention relates to a freshwater fish culture technology, in particular to a grass carp ecological culture method. Background technique [0003] my country's fish farming output ranks first in the world for a long time, and grass carp is one of the four unique domestic fishes in my country. It grows rapidly, has strong adaptability, a wide range of bait sources, high yield, and rich nutrition. It is the main aquaculture species in my country. However, at present, the pond water is in a stagnant state, and the water quality is easy to deteriorate; the taste of grass carp fed with artificial concentrated feed is worse than that of natural grass carp, the meat quality is loose, and the umami taste decreases; while the grass carp fed with pure green feed has a long growth cycle, which cannot meet the needs of the market. need. When grass carp is monocultured, the species is single, the pond space and bait are not fully utilized, and the b...

Problems solved by technology

However, at present, the pond water is in a stagnant state, and the water quality is easy to deteriorate; the taste of grass carp fed with artificial concentrated feed is worse than that of natural grass carp, the meat quality is loose, and the umami taste decreases; while the grass carp fed with pure green feed has a long growth cycle, which cannot meet the needs of the market. need

When the grass 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 grass carp is mixed, it is necessary to choose a reasonable species and quantity, which is in line with the ecological cycle of the pond.
