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

Embodiment 1

[0013] 1. The water source is natural mountain spring water. A 5-acre pond is excavated at the lower terrain of the water source, and the water pipes are used to divert water naturally. Two water injection ports and two drainage ports are set at the four corners of the pond, and the water injection flow rate is 0.1m 3 / s, open the drain at the same time to keep the pond running.

[0014] 2. The fermented feed uses 0.05% of yeast, 0.03% of lactic acid bacteria, and 0.01% of Bacillus as starter, 55% of corn flour, 25% of wheat bran, and 20% of distiller's grains as fermentation substrates. made of grains.

[0015] 3. The grass feed is 25% ryegrass, 25% elephant grass, 20% duckweed, 8% water spinach, 10% sweet potato vine, 10% cassava leaves, and 2% cucumber, chopped and fed directly.

[0016] 4. The ratio of yeast feed to grass feed is 3:7. The amount of feed fed was 3‰ of the total weight of the fish, twice a day.

[0017] 5. The polyculture method is as follows: Fry stockin...

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...
