Surrogate broodstock technology uses substitute individuals to produce young of other species using PGC and Gonical cells collected from donor fishes and intraperitoneally injected into recipient larvae or adult ones known as surrogate. The viability and density of PGC and Gonical cells are checked for better selection. A novel method for producing more donor fish species by using a recipient one. It speeds up the breeding process and closes the donor's generation gap. A quick and easy way to have more young ones using the surrogate method without causing any generational or genetic issues.
