| Summary: | Estimates of reproductive potential for Div. 3NO cod were produced by sequentially incorporating estimates of proportion mature-at-age, sex ratio-at-age and potential egg production. The estimates of reproductive potential produced by each method were broadly similar but there were important differences. This leads to differing perceptions of the stock productivity as measured by relative recruitment rate of a stock and in the spawner stock produced per recruit. An example is illustrated of how these different estimates of reproductive potential can be used in the determination of biological limit reference points and in projections of stock size. |
