5203 |a"Estimates of among sample and within sample variance in proportion-at-age for Pacific ocean perch (Sebastes alutus) were used to examine optimum sampling strategies. The results agree with those in the literature to indicate that, for two-stage sampling, a sample size of more than 100 probably represents over-sampling. If reducing sample size will lead to any increase in the number of samples collected, then optimal sample size may be closer to 50. Furthermore, if the resources available for ageing the specimens are limited such that only a fixed number of specimens can be aged from the pool of samples, then specimens should be drawn from as many samples as possible, rather than ageing all specimens from some samples"--Abstract, page iii.
