The invention discloses a directional
mating method for
Penaeus vannamei Boone. The method includes the steps that parent prawns are selected and subjected to
nutrient enrichment cultivation, a
mating scheme is set, male prawns are ripened and independently cultivated, female prawns are ripened and independently cultivated, directional
mating parent prawns are selected and subjected to directional mating, and spawning and fertilization are performed. The method is designed according to the life habits and the mating, fertilization and spawning characteristics of the
Penaeus vannamei Boone, and possible injuries to the male prawns and the female prawns in the
artificial fertilization process can be avoided. In the whole mating process, it is only needed to determine the serial numbers of the parent prawns for mating, operation is convenient and easy, and the genealogical relationship of established families can be accurately established. The genetic relationship of the individuals of the families is determined, the mating scheme is designed artificially, and
inbreeding depression of the established families can be effectively avoided. The method has the advantages of being high in success rate and low in parent
prawn loss, and overcomes the defects that in the prior art, when
Penaeus vannamei Boone families are established in an
artificial fertilization mode,
spermatophore is prone to falling off, the fertilization rate is low, and half sibs cannot be established easily.
