COMPARISON OF THE PRECISION OF DIRECT VERSUS AGE LENGTH KEY METHODS OF ESTIMATING CATCH-AT-AGE PROPORTIONS
Abstract: Catch-at-age proportions can be estimated directly using a simple random sample (SRS ... ) of fish in the catch, determining the ages in the sample, and calculating proportions in each age class ... . This “direct” method can be replaced by the age length key (ALK) method if there are in addition to the SRS ... of ages, which have also been measured for length (the age-length sample), a large SRS where fish ...
