Transgenic Shrimp:Current Status and Future Perspectives

Shrimp culture is important to the economy of many countries,strains of shrimp that are fast growth or disease resistance would be highly desirable.Transgenic techniques offer two significant advantages over conventional selective breeding: the ability to exploit genes and DNA constructs across species barriers; the very fast process for improved growth or other characteristics.Transgenic shrimp have future perspectives for potential applications in aquaculture.However,the transgenic research in shrimp is still in its infancy.Standard techniques for foreign genes transfer have been difficult to apply to shrimp species of aquaculture,efficient transformation vectors are not yet available.We need more knowledge on shrimp genes,promoter and transgenic vector; the possible risk to the environment needs to be evaluated also.
