ABSTRACT:
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.
