This chapter emphasizes the use of isozymic genetic data in studies of fish populations with special focus on the application of this data to the culture and management of fish populations. We have directed much discussion toward salmonid fishes because of the importance of salmonids and our own extensive experience with this group, although the same principles are applicable to other organisms. A preliminary methodology section is presented which emphasizes the amount of genetic information available and the importance of confirming the genetic basis of electrophoretic variants. An overview of some of the areas where isozyme studies have been used in the study of fish populations is followed by a more detailed examination of the concept of the amount and distribution of genetic variation in populations of fish. The final section discusses the management applications of this population genetic data in both artificial and natural populations of fish.
