This invention is about triploid breeding method for different shrimp
species especially to the triploid production both in cold-warm water
shrimp and tropical species, including the induction of MI triploid
shrimp, the triploid induction methods for different shrimp and the
development and utilization of revulsants for triploid shrimp. The
triploid of cold-water shrimps were obtained by collecting the fertilized
eggs and heat shock treatment; while the triploid induction of tropical
shrimps were obtained with collection of the fertilized eggs, treatment
of the revulsants or cold shock. The advantages of the invention are as
follows: it has determined the optimal-inducing processes and methods for
different species of shrimps, and led to the inducing rate increased
distinctly; It also has determined the optimal-inducing methods for MI
triploid shrimp, and led to the inducing rate increased distinctly
without the destroy of eggs; The revulsants which led to high inducing
efficiency in this invention are nontoxic, so the operation security and
the safety to environment are improved.
