European Union – Measurement of capacity in CCAMLR exploratory fisheries in Subareas 88.1 and 88.2
Abstract: The longline fishery for toothfish in the Ross Sea currently operates as an Olympic ... fishery. The number of vessels operating in the fishery has progressively increased in recent years yet ... overall catch limits have remained relatively stable and as a consequence the fishing opportunities for ... individual vessels have reduced. This report investigates recent trends in the development of the Ross Sea ...

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 ...

Acoustic data analysis and models of krill spatial distribution
Abstract: Acoustic data obtained on the 4-5 January 1987 aboard the R/V Professor Siedlecki were ... space, semivariogram (spatial autocorrelation of krill biomass) and the frequency distribution of krill ... biomass estimate. The wavenumber spectrum resembles a white noise at scales of 2-20 km, although at scales ... smaller than 1 km the spectrum appears to lose its power significantly. The semivariance of biomass does ...
