Abstract

The invention discloses an intensive culture and large-scale reproduction technique for parent pelteobagrus fulvidraco, which includes the following steps: selection, pond conditions, pond cleaning, periodical gonad examination, artificial spawning facilities and spawning induction and artificial insemination. The mature coefficient of parents in ponds is higher than the mature coefficient of wildpelteobagrus fulvidraco at the same stage, the ovaries of the female fishes are more orderly than the ovaries of wild pelteobagrus fulvidraco at the same stage, the ovaries are full, male testes arebright, the number of branches are large, and the time of reproduction can be reached earlier; equipment needed by a centralized aerated culture method is simple, the technique is easy to operate, andnot only can size be increased, but also the survival rate of fries can be ensured.

Description

technical field [0001] The invention relates to a technique for intensified cultivation and large-scale reproduction of broodstock of yellow catfish. Background technique [0002] Pelteobagrus fulvidraco belongs to clamformes (Siluriformes), crocodile family (Bagridae), yellow fish genus (Pel teobagrus), also known as ounce fish or cattle fish, it is common in rivers, lakes and ditches in my country. It is an economic fish. Its meat is tender, delicious, rich in protein, low in fat, free of spines, sweet and flat in taste, can benefit the spleen and stomach, diuretic and reduce swelling. It is welcomed by consumers and has a large market potential. It is an excellent species for the adjustment of fishery industry structure. In recent years, artificial breeding experiments have been carried out in succession all over the country, but there are few studies on the early breeding of yellow croaker. The basis of early breeding of yellow croaker is the early maturation of parent fis...
