2. Comparison of age- and length-based harvest control rules for the South Georgia icefish (Champsocephalus gunnari) fishery

   Abstract:  An age-based operating model was constructed and used to derive an initial numbers ... at age vector for the population. An age-based harvest control rule was then applied using the operating ... model dynamics and assuming perfect knowledge of the resource (initial numbers at age, maturity ... and weight at age). The initial numbers at age was also converted to numbers at length, which was used ...

6. 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 ...
