The invention discloses a method for obtaining
crassostrea hongkongensis monomers through
medicine induction. The method comprises steps of cultivating larvae, screening larvae at foot and face growing stage, performing
medicine induction, performing cultivation with descending flows, performing
juvenile mollusk management and the like. Cultivation is performed according to the
crassostrea hongkongensis fry breeding technical regulations, larvae are screened to obtain larvae at foot and face growing stage of which the specifications are 300-350[mu]m, then the larvae at the foot and face growing stage are induced with inducing liquid, then cultivation is performed with the descending flows, and after 8-10 days,
crassostrea hongkongensis
monomer juvenile mollusks of which the shell height is1-2mm can be obtained. According to the method disclosed by the invention, through
medicine stimulation, the
larva at the foot and face growing stage can be smoothly induced,
low distortion ratio andsecondary hurt during base removal are avoided, the non-adherence
distortion ratio of the larvae is greatly increased, the
distortion ratio of the larvae is 60% or above, the larvae which are not successfully induced can be recovered for continuous cultivation, after feet appear, induction is performed anew, and the problems that
crassostrea hongkongensis fries are easy to damage, the
survival rate is low and the yield in unit
water body is low in breeding process can be solved.
