    Techniques for artificial rearing of commercial edible oysters have already been worked out. the oysteris generally regarded as a prime candidate for intensive aquaculture. Yet to be achieved is the true domestication of the oyster with the development of a variety of different strs so well suited to the methods of intensive culture in hatcheries that a margin of profit is reasonably assured a commercial breeder. Domestication along with some genetic interference with the course of wild populations could further assure that this pelecypod mollusc contributed to the world food supply to the limit of its not insignificant potential. Such 'domestication' can be achieved by the deliberate application of genetic methods or. Over a longer period, by trial and error breeding. Most likely, it will be accomplished through the combined efforts of researchers and commercial producers, the developments of one opening new avenues of approach to the other. This paper tells what is known already about the genetics of the oyster, reviewing such information in the light of its significance in the application of different breeding programs to oysters and to the introduction on natural beds of specially bred new oyster stocks to old wild populations. The review 1st presents background information on the cytogenetics of oysters, then goes on to consider them in the perspective of inbreeding, selective breeding, intra-and inter-spp hybridization, and finally in respect to use in the future of induced mutations in special breeding programs.
