Sampling toothfish from longlines with unequal probabilities
Abstract: To obtain a representative sample of the catch taken by toothfish longliners, CCAMLR ... observers are recommended to sample a quota of the first 30 fish that are caught during a sampling session ... proportion to toothfish density on the line. The present recommendation therefore indicates sampling with ... vital rates. To resolve this, either the probabilities need to be incorporated in the analysis of ...
