A green ecological highly-efficient grass carp and river snail mixed culture method

Abstract

The invention provides a green ecological highly-efficient grass carp and river snail mixed culture method comprising the steps of selecting a place and building a pond, disinfecting and fertilizing the pond, putting fries in the pond, feeding grass material to the fries, decontaminating the pond and preventing diseases, and catching products. In the method, only green grass is fed and no other fodder is fed, and excrement discharged by grass carps after the grass carps eat the green grass is best-quality fodder for river snails, so that water quality pollution is greatly reduced, fodder waste is reduced, the culture cost is reduced, the yield of grass carp and river snail breeding is increased, the quality of grass carps and river snails is improved, and the production benefit, the economic benefit and ecological benefit are increased.

Description

technical field [0001] The invention relates to a green ecological high-efficiency polyculture method for grass carp and snails, belonging to the technical field of aquaculture. Background technique [0002] Grass carp generally likes to live in the middle and lower layers of the water and areas with many aquatic plants near the coast. It has a simple diet, fast growth, high yield, tender and delicious meat, rich in unsaturated fatty acids and selenium, and regular consumption has anti-aging and beauty effects. It is good for blood circulation and is a good food for cardiovascular patients. Escargot belongs to the mollusk phylum Gastropoda Probranchia Snailidae, mainly eats tender stems and leaves of aquatic plants, organic detritus, etc. It has high requirements on water quality, low yield, and contains protein, fat, vitamins, etc. At present, a single species is raised in ponds alone, and the three-dimensional space and natural bait of the pond have not been rationally ut...

Problems solved by technology

At present, a single species is raised in ponds alone, and the three-dimensional space and natural bait of the pond have not been rationally utilized. Due to the unreasonable mix of mixed cultures, water pollution is likely to occur and the cost will increase.
