Culturing method for high-yield of grass carps

Abstract

The invention relates to the technical field of aqua-culturing and concretely relates to a culturing method for high-yield of grass carps. The culturing method for high-yield of grass carps comprises steps of building and processing a pond, selecting and releasing fries, releasing forage and managing water quality. The forage is mainly formed by the following raw material via a fermentation way according to weight by parts: 13 to 15 parts of Cirsium shansiense, 15 to 17 parts of mountain-grown Gypsophila paniculata, 13 to 15 parts of roxyama, 15 to 17 parts of Coral dealbatus, 17 to 20 parts of pigweeds, 15 to 17 parts of sudangrass, 17 to 20 parts of lemongrass, 12 to 14 parts of wormwoods, 10 to 13 parts of negundo chastetree fruits, 10 to 15 parts of quispualis indica, 15 to 17 parts of loranthus parasiticus, 15 to 17 parts of pyrola, 10 to 15 parts of giant knot weeds, 10 to 15 parts of large-leaved gentian, 10 to 12 parts of beet pulp, 8 to 10 parts of silkworm chrysalis, 10 to 12 parts of earthworm powder, and 1 to 2 parts of microorganism. The culturing method can provide forage with rich nutrients and enhance immunity of the grass carps; grass carp healthy growth and survival rate can be promoted; and fresh and tasteful meat can be achieved.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a high-yield breeding method for grass carp. Background technique [0002] Grass carp belongs to the genus Grass carp of Cyprinidae Cyprinidae, Yaluo subfamily. The common names of grass carp are: grass carp, grass carp, oil carp, grass carp, white carp, grass carp, mixed child, black herring, etc., inhabiting rivers and lakes in plain areas , generally like to live in the middle and lower layers of water and areas with many aquatic plants near the shore. Grass carp has the advantages of strong adaptability, fast growth, large individuals, wide feeding habits, few diseases, and delicious meat. It is suitable for ponds, reservoirs, and lakes. It is a breeding species with good economic and social benefits. One of the four major domestic fishes in freshwater farming in China. Due to the above-mentioned advantages of grass carp, it is also easy to become a food on the table. H...

Problems solved by technology

Due to the above-mentioned advantages of grass carp, it is also easy to become a food on the table. However, in order to maximize the profit, many manufacturers often increase the growth rate of fish, increase the production of fish, and reduce the incidence of disease. Adding feed additives containing chemical drugs, antibiotic drugs and hormones to the compound feed for prevention and treatment will not only cause drug residues in the fish, but also pollute the water quality and affect the environment. Harm to consumers' health

Even in this way, the situation of the existing grass carp aquaculture industry has not been improved, and problems such as low survival rate, high incidence of disease, and slow growth of grass carp cannot be overcome.
