Embodiment 1

[0027] Embodiment 1 A kind of breeding method of money fish

[0028] The breeding method of described money fish is divided into the following steps:

[0029] S1. Routine breeding of broodstock: broodstock are artificially bred from wild seedlings, and feed A feed when juvenile fish are fed. A feed consists of the following ingredients and their parts by weight: 35 parts of soybean powder, 18 parts of rice flour, and 46.4 parts of Artemia larvae , 0.4 parts of vitamin C, and 0.2 parts of probiotics; feed B feed after 12 months, and the B feed consists of the following ingredients and parts by weight: 35 parts of corn gluten powder, 3 parts of epimedium powder, and 45 parts of minced fish , 16.5 parts of spirulina, 0.5 part of saccharoterpenoid; twice a day, the feeding amount is 4.5‰ of the fish weight in the pond;

[0030] S2. Intensive cultivation of broodstock: select well-developed female broodstock in step S1 and male fish with no scars on the body surface and quick resp...

Abstract

The invention belongs to the field of aquaculture and particularly relates to a breeding method for scatophagus argus. The breeding method is characterized in that scatophagus argus bred in a pond isselected as parent fish which is subjected to five links of conventional cultivation, strengthened cultivation, artificial spawning, artificial incubation and seed rearing, so that a rate of inducingspawning can reach 100%, a fertility rate is 90% or more, and a hatchability rate of fertile eggs is 93%. The breeding method successfully builds a totally artificial breeding technology of the scatophagus argus, and can be used for large-scale production and breeding of the scatophagus argus.

Description

technical field [0001] The invention belongs to the field of aquaculture, and in particular relates to a breeding method of money fish. Background technique [0002] Money fish (Scatophagus argus Linnaeus1766), commonly known as golden drum fish, has a beautiful body, colorful colors, docile temperament, and delicious meat. It is a rare seawater economic fish with ornamental and edible value. Money fish has strong environmental adaptability and disease resistance. It can not only grow and develop in seawater and brackish water, but also is suitable for freshwater culture. It has become an important species in ponds and cages in southern my country in recent years. Its economic value is extremely high. high. Due to the intensified construction of various coastal projects, environmental pollution and excessive fishing, the environmental quality of fishery waters and the regeneration of aquatic resources have been seriously affected. Carrying out the research and development o...
