Taking Stock of Genetic Concepts in Fisheries Management

摘要: The historical development of the idea isolated stocks fish that can be managed as separate management units has been strongly tied to intuitive races it practical necessities jurisprudence and estimation both biomass sustainable yield by fisheries managers. Demonstrating existence delineating their boundaries generally proved unsuccessful. Various techniques ranging from meristic count differences polymorphic allelism have usually failed. However, in pursuit stocks, biochemists uncovered a great deal information about variation allele frequencies over time space. Following shift opinion away stochastic natural selection mechanisms frequency variation, is evident observed allows more insight into biology fishes than breeding structure populations. These insights argue agai...
