Artificial propagation method for botia superciliaris

Abstract

The invention discloses an artificial propagation method for botia superciliaris. The method comprises the following steps of 1 wild parent fish collecting and domesticating, 2 parent fish breeding, 3 artificial spawning, 4 artificial inseminating and 5 artificial incubating. The method is simple, high in operability and good in practical applicability, large-scale and industrialized production of botia superciliaris fries can be achieved, development of botia superciliaris breeding industry is promoted, and botia superciliaris wild resources are effectively protected. Tests show that the survival rate of the botia superciliaris bred in a circulating water system ranges from 80% to 85%, the induced spawning rate ranges from 70% to 75%, the fertilization rate ranges from 40% to 45%, and the incubating rate ranges from 70% to 80%.
