Examination of the characteristics of the fishery for Dissostichus eleginoides in the CCAMLR Statistical Subarea 48.3 and its implications on estimating trends in catch per unit effort
Abstract: We investigate the spatial and temporal (i.e. fishing season) variation both systematic and random in haul-by-haul catch and effort data from the longline fishery for Dissostichus eleginoides in Subarea 48.3. We concentrate on presenting the results of preliminary work on the potential

Age-structured production model for toothfish at South Georgia
Abstract: The ASPM model used by Agnew and Kirkwood (2004, WG-FSA-04/82) has been modified through the introduction of a new annual selectivity function, modelled as a unimodal, algebraically decaying function of age, with three easily interpretable parameters. When only a single selectivity curve

Selectivity-induced bias in growth parameter estimates
Abstract: A short simulation study has been carried out to investigate the size of the bias in estimates of growth parameters resulting from fish of different sizes having different probabilities of being included in catch samples. Fish were included in catch samples from the population with

Geographical differences in the condition, reproductive development, sex ratio, and length distribution of Antarctic toothfish (Dissostichus mawsoni) from the Ross Sea, Antarctica (CCAMLR Statistical Subarea 88.1)
Abstract: A number of morphological and reproductive measurements made seasonally on Antarctic toothfish Dissostichus mawsoni from mid-December to early April during the 2000-01 to 2004-05 fishing seasons aboard the autoliner San Aotea II have been analysed. Results of this study indicate

Mitigation trials and recommendations to reduce seabird mortality in the pelagic icefish (Champsocephalus gunnari) fishery (Subarea 48.3)
Abstract: Trials were conducted during the 2004/5 mackerel icefish (Champsocephalus gunnari) season in sub-area 48.3, to quantify seabird interaction with fishing operations, to trial different mitigation methods in an attempt to reduce seabird mortality caused by entanglement with the net and to

A method for inferring movement rates of fish from mark–recapture data
Abstract: This paper presents methods to infer the rate of movement of fish that are marked, released, and subsequently captured. The information that is available is the location and date of the release and the recapture. In addition, the intensity of fishing effort (i.e. sampling) by location

Seabird abundance and by-catch on Brazilian longline fishing fleet
Abstract: Southern Brazil is an important foraging ground for several albatross and petrel species during breeding and non-breeding seasons. We present information on seabirds attending longline fishing vessels on Brazilian Exclusive Economic Zone and international waters of the Southwestern

By-catch in the Australian fisheries in Division 58.5.2
Abstract: This paper presents bycatch information for the Australian fisheries in Divisions 58.5.2 for the 2003/2004 and 2004/2005 seasons. Bycatch in the trawl fisheries was low, generally less than 1% of the total catch (target plus bycatch). Higher percentage bycatch rates occurred in trawling
