Rabbitfish siganus oramin parent fish rearing method

Abstract

The invention discloses a rabbitfish siganus oramin parent fish rearing method, which comprises the following steps: S1, trapping wild young fish in the natural environment, and then feeding the youngfish respectively in different net cages of the same pond according to trapped months; S2, maintaining the water body and water quality of the pond to be stable, and breeding the young fish for a period of time until the young fish grow and develop to maturity; S3, choosing individuals, which have large bodies, good vitality and wound-free body surfaces, as parent fish from sexually mature fish,and carrying out maturity inspection on the parent fish; and S4, carrying out artificial spawning induction and fertilization on mature fish. The life habit of rabbitfish siganus oramin is utilized tofeed the young fish in the different net cages of the same pond according to the trapped months, the mature degrees of parent fish reared in each batch can be different in different seasons, meanwhile, the young fish in each net cage basically develop to mature within the same period of time, the manpower, material resources and time required for screening the parent fish are substantially reduced, and the competitiveness of the parent fish is improved.

Description

technical field [0001] The invention relates to the technical field of production and breeding, in particular to a method for cultivating broodstock of macular basketfish. Background technique [0002] The yellow-spotted basketfish, commonly known as mudmen and stinky-bellied fish, belongs to Perciformes, Basketfishidae, and Basketfish genus. It is a small nearshore fish with a wide distribution. It is distributed in the East China Sea, South China Sea and Taiwan Sea. Its meat is tender and delicious, and is deeply loved by consumers; because of its omnivorous and herbivorous feeding habits, and its preference for algae, it has the advantages of easy feed source, low breeding cost, strong disease resistance, clean netting, and feeding Short cycle and many other advantages. In recent years, it has developed rapidly in the coastal area of ​​South China, and has become one of the new objects of main and polyphagous omnivorous fish culture in offshore seawater cages. The market...

Problems solved by technology

However, no substantive breakthrough has been made in the fully artificial large-scale breeding of the macular basketfish. At present, the cultured seedlings of the macular basketfish in my country are mainly directly caught from natural sea areas, and its quantity and quality are difficult to meet the development of its aquaculture industry.
