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 / S.G. Candy, A.J. Constable, T. Lamb, R. Williams.

Abstract: | A von Bertalanffy (VB) growth model with young-age adjustment was fitted to length-at-age data for Patagonian toothfish caught by Heard Island trawl fishery during three research cruises prior to 1997 and commercial cruises from 1999-2003, taking into account length-bin sub-sampling process used to select fish for ageing from random length-frequency samples, and also an assumed length-dependent fishing selectivity function. When predictions from Fabens form of VB model were compared to growth rates obtained from mark-recapture studies, although in general growth was over-predicted, model fitted using definition of maximum likelihood that incorporated variable probability sample selection gave greater correspondence to mark-recapture growth than that obtained when sampling probabilities were ignored. |
