Genetic concerns about hatchery populations - a comment on the conclusions of Nyman and Ring



Genetic concerns about hatchery populations - a comment on the conclusions of Nyman and Ring



Journal of Fish Biology 42.4



Some conceptual problems in the paper by Nyman and Ring (Nordic Journal of Freshwater Research (1989) 65, 34-43) are addressed. They concern (1) sampling strategies for studies of genetic relationships among populations, (2) the need for empirical validation of the theoretically derived effective number of parents needed to avoid excessive inbreeding and genetic drift, and (3) the applicability of biochemical polymorphisms as genetic tags in the management of fish populations.
