Estimation of effective number of breeders and effective population size in an abundant and heavily exploited marine teleost.

ABSTRACT: Obtaining reliable estimates of the effective number of breeders (N _b) and generational effective population size (N _e) for fishery-important species is challenging because they are often iteroparous and highly abundant, which can lead to bias and imprecision. However, recent advances in understanding of these parameters, as well as the development of bias correction methods, have improved the capacity to generate reliable estimates. We utilized samples of both single-cohort young of the year and mixed-age adults from two geographically and genetically isolated stocks of the Australasian snapper (Chrysophrys auratus) to investigate the feasibility of generating reliable N _b and N _e estimates for a fishery specie
