Abstract
Selective breeding for genetic improvement of production traits has great potential to increase the efficiency and reduce the environmental footprint of aquaculture. When surrogate broodstock technology is combined with genomic selection to predict breeding values of embryos or juveniles, it could potentially reduce the generation interval without substantial loss of selection accuracy. This article has in detail reviewed the methodology of surrogate broodstock technology including sterilization methods, transplantation approaches and its application in aquaculture. It also has provided an overall knowledge on the successful manipulations of germ cell transplantation so far carried out in the world.
