A von Bertalanffy growth model for toothfish at Heard Island fitted to length-at-age data and compared to observed growth from mark–recapture studies
using a von Bertalanffy (VB) growth model taking into account response-biased sampling of fish that were ... assuming normal errors with constant coefficient of variation using iteratively weighted least squares ... using VP maximum likelihood (MLP) with length-bin relative probabilities defined using fishing ... developed and showed that the bias is relatively small for the range of release lengths in the data ... with this approach is that freedom from bias in the estimated VB parameters is dependent on the other ... probabilities may be involved in selecting fi sh from the LF sample. One sampling scheme that could be used is ... the on-deck LF sample with the particular implementation of general RS sam- pling that is described ... assumed to be known for this study, with its most important feature being a sharp decline in selectiv ...
