Importance of Surrogate Broodstock for Aquaculture

Broodstock that are difficult to propagate in captivity or for those the breeding protocol is yet to be developed are often collected from the wild and maintained in a large land-based tank, and fertilized eggs are collected using an egg collection net set at the water outlet of the tank. Many aquaculture fish species have longer reproductive maturation time. Generally, closely related fish species that is prolific breeder and for which the breeding protocol is well established should be chosen. In summary, surrogate broodstock technology can be useful to accelerate breeding and preserve the genetic information of elite germplasm. Surrogate broodstock technology does not artificially manipulate cellular contents (unlike gene recombination or nuclear transfer technologies), which could make it advantageous for application on an industrial scale. However, there are few concern that has to be addressed before surrogate broodstock technology can be applied to the aquaculture industry.
