Recombinant DNA methodology is used to construct the gene that is intended to express desirable qualities during the growth and development of the recipient animal. Gene transfers have been successful in various fish such as common carp rainbow trout Atlantic salmon catfish goldfish zebra-fish etc. Sheep goats pigs cows rabbits rats mice fish insects parasites and even humans have previously been used in this modification process.

Transgenic animals are created by deliberately inserting a gene into the genome of an animal. Not all of the complete genetic material is initially transferred only one or several genes which have been previously. This lecture states some mechanisms to develop healthy transgenic animals.

A transgenic animal is one that carries a foreign gene that has been deliberately inserted into its genome. Transgenesis is the process by which mixing up of genes takes place. Depending on the purpose of the transgenic fish studies the embryos of some fish species are better suited for gene transfer studies than the others.
