A von Bertalanffy growth model for Division 58.5.2 fitted to length-at-age data and a comparison of predicted with observed growth from mark–recapture data
Abstract: Length-at-age data for the Patagonian toothfish (Dissostichus eleginoides) caught by ... ) data used to obtain the samples of fish for ageing used length-bin sampling involving a fixed sample ... size per bin. Estimation of the VB parameters used a definition of the maximum likelihood which took ... the additional affect of length-bin sampling on sampling probabilities. Estimation of the trawl ...

Depletion-corrected average catch: a simple formula for estimating sustainable yields in data-poor situations
Abstract: The depletion-corrected average catch (DCAC) formula is an extension of the potential ... -lived species. Over an extended period (e.g. a decade or more), the catch is divided into a sustainable ... biomass. The size of the windfall is expressed as being equivalent to a number of years of sustainable ... production, in the form of a “windfall ratio”. The DCAC is calculated as the sum of catches divided by the ...
