Abstract:Population size is a key parameter for the conservation of animal
species. Close-kin mark-recapture (CKMR) relies on the observed
frequency and type of kinship among individuals sampled from the
population to estimate population size. This approach requires being
able to determine the age of sampled individuals. One common approach,
particularly in fish studies, is to measure animal length and using an
assumed age-length relationship (a ‘growth curve’). We used simulation
to test the effect of misspecifying th… Show more
