2. Proportional recruitment indices of Antarctic krill from Japanese fisheries data in Subareas 48.1, 48.2 and 48.3 during 1980 through 1997

   around the Elephant Island. However, the values especially R1 in this study were extremely smaller than ... Siegel et al. (1 998)'s values. This may be due to the net selectivity and/or incomplete coverage of ... the distribution of small krill by commercial fisheries. Inter-annual pattern of R1 and R2 in Subarea ... 48.2 showed somewhat similar pattern to Subarea 48.1. However, because of inconsistency of the ...

3. A perspective on steepness, reference points, and stock assessment

   these patterns. For the production model, we derive explicit relationships for steepness and life ... history parameters and then for steepness and major reference points. For the age-structured model, we are ... required to generally use numerical computation, and so we provide an example that complements the ... analytical results of the production model. We discuss what it means to set steepness equal to 1 and how to ...

5. Modelling krill recruitment

   Abstract:  A method is developed for using observed values of the mean proportion of recruits and ... its variance to model recruitment in a krill population in terms of numbers of recruits. The method ... includes the calculation of natural mortality and other parameters consistent with the observed ... which are consistent with the statistical uncertainty in the observed recruitment parameters.
