Abstract

Surrogate broodstock development by stem cell transplantation is a powerful reproductive biotechnology for the conservation and propagation of fish genetic resources. In recent time, the technique has gained much attention due to the enormous potential for application in reproductive medicine and stem cell therapy. Currently, the field application of stem cell transplantation in teleost has been broadly restricted to propagation of commercially important fish species such as production of Bluefin tuna through Mackerel recipient. Nevertheless, stem cell transplantation technique has also application beyond this and could play a pivotal role in fishery resources management in open water bodies such as lake, reservoir etc. Recent reports have revealed that, invasive fish species in lake and reservoir have caused potential damage to the ecosystem resulting into decline in native fish population. One of the classical example is entry of African catfish Clarias garipinus and Channel catfish Ictalurus punctatus to Asian water bodies. The impact has been such that, some of the valuable native fish species of the region are on the verge of extinction. It is also true that, such invasive fish species are extremely difficult to control in large size water bodies. In this scenario, turning the invasive fish species into surrogate parents could be a viable alternative to arrest the proliferation of such fish population.
