INCORPORATING SAMPLING VARIATION AND RANDOM READER ERROR INTO CALCULATION OF EFFECTIVE SAMPLE SIZE IN THE APPLICATION OF AGE LENGTH KEYS TO ESTIMATION OF CATCH-AT-AGE PROPORTIONS
Abstract: Catch-at-age proportions are generally incorporated into an integrated assessment ... for both the variation associated with sub-sampling of the random length frequency (LF) sample for ageing ... , and random reader error when ageing fish. The catch-at-age ESS is estimated by dividing the ESS for the LF ... obtained from simulated samples of age frequency data. These samples are obtained using Monte Carlo ...
