4. Estimating fishing gear selectivity for Patagonian toothfish (Dissostichus eleginoides) caught by trawlers on the Heard Island plateau region (Division 58.5.2) using trawl and longline length frequency data and forward-calculated continuation ratios

   . In the first stage I estimate a parameter for each 40 mm wide length bin from the fit of a binomial ... generalised linear mixed model (GLMM) to the number of fish in the bin using a logit link function and ... binomial sample size defined as the number of fish in that bin or greater.
