Problems solved by technology

However, at present, the pond water is in a stagnant state, and the water quality is easy to deteriorate; crucian carp fed with artificial concentrated feed has a poorer taste than natural crucian carp, with loose meat and reduced umami taste; crucian carp fed with pure green feed has a long growth cycle and cannot meet the needs of the market. need
When crucian carp is raised in monoculture, the species is single, the pond space and bait are not fully utilized, and the benefit is low. When mixed, the species and quantity need to be selected reasonably, which is in line with the ecological cycle of the pond

Embodiment Construction

[0010] 1. The water source is natural mountain spring water. A pond of 5 acres 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 each of the four corners of the pond. The water injection flow rate is 0.1m3 / s, and they are open at the same time Outlets to keep the pond running.

[0011] 2. The fermented feed uses 0.05% of yeast, 0.03% of lactic acid bacteria, and 0.01% of Bacillus as the starter, 55% of corn flour, 25% of wheat bran, and 20% of distiller's grains as the fermentation substrate. made of grains.

[0012] 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.

[0013] 4. The ratio of fermented feed to grass feed is 3:7. The amount of feed fed was 3‰ of the total weight of the fish, twice a day.

[0014] 5. The polyculture metho...

Abstract

The invention provides a breeding method of crucians. In the method, natural pollution-free mountain spring water is adopted, biological fermentation fodder and grass fodder are used, water quality is regulated by simulating mixed ecosystem breeding, traditional Chinese herbal medicines are used for fish disease control, no chemicals are added during the breeding process, and bred fish are fresh and smooth, free of mud smell and are good aquatic products green and pollution free.

Description

technical field [0001] The invention relates to a freshwater fish culture technique, in particular to a crucian carp culture method. Background technique [0002] my country's fish production ranks first in the world for a long time, and crucian 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; crucian carp fed with artificial concentrated feed has a poorer taste than natural crucian carp, with loose meat and reduced umami taste; crucian carp fed with pure green feed has a long growth cycle and cannot meet the needs of the market. need. When crucian 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 carp is mixed, it is nece...
