Observer coverage required for the prediction of incidental capture of seabirds in New Zealand commercial fisheries
Abstract: This report obtains estimates of observer coverage required to predict the total numbers of incidental seabird captures (albatross and petrel taxa combined) in a fishery with a specified coefficient of variation. Fisheries analysed are determined by the quality and the availability of

Review of the population status and national research conducted by New Zealand on Southern Ocean seabirds vulnerable to fisheries interactions
Abstract: Research undertaken in New Zealand on seabird interactions with fisheries, and research into the population status and distribution at sea of New Zealand seabirds is documented. Author(s): E.C. Garland and S.M. Waugh (New Zealand) Title: Review of the population status and national

A two-fleet ASPM assessment of the toothfish (Dissostichus eleginoides) resource in the Prince Edward Islands vicinity
Abstract: The ASPM assessment of the Prince Edward Islands toothfish resource by Brandão and Butterworth (2004) that permitted annual fluctuations about a deterministic stock-recruitment relationship is updated to take account of further catch, GLM standardised CPUE and catch-at- length

Age validation of Patagonian toothfish (Dissostichus eleginoides) from Heard and Macquarie Islands
Abstract: Patagonian toothfish, (Dissostichus eleginoides) have traditionally been aged by counting presumed growth increments on the sectioned face of sagittal otoliths. While there is a general consensus that the observed increments represent annual events, no direct validation has been provided

First increment validation of Patagonian toothfish (Dissostichus eleginoides) from Heard Island
Abstract: Patagonian toothfish, (Dissostichus eleginoides) have traditionally been aged assuming one opaque and one translucent increment is formed each year on the sectioned face of sagittal otoliths. It has been recorded that differences in otolith interpretation exist between institutes

Results from the New Zealand exploratory fishery for Dissostichus spp. in Divisions 58.4.1 and 58.4.2 in the 2004/05 season
Abstract: The New Zealand longliners Janas and San Aspiring were authorised to operate in the Exploratory Fishery in Divisions 58.4.1 and 58.4.2 during the 2004-05 season. The results from their first season in this fishery are presented. Janas undertook 44 sets in Division 58.4.2 for a catch of

Size at maturity and histological procedures explored to determine spawning activity of female Dissostichus mawsoni from samples collected from the Ross Sea in January 2004, December 2004 and January 2005
Abstract: Gonad samples from female Antarctic toothfish (Dissostichus mawsoni), collected during the 2003/04 and 2004/05 commercial fishing seasons in the Ross Sea to improve estimates of size of maturity, were analysed macroscopically and histologically. Progress was, however, limited because few

Growth models for D. eleginoides for the Heard Island plateau region (Division 58.5.2) calibrated from otolith-based length at age data and validated using mark-recapture data
Abstract: Length-at-age data for the Patagonian toothfish (Dissostichus eleginoides) caught by trawl in Division 58.5.2 were fitted using von Bertalanffy (VB) and segmented-linear models using a likelihoods that either did or did not incorporate fishing selectivity and the length-bin sampling

On necessity of reconsideration of geographic boundaries, TAC estimates and duration of research fishing of Antarctic toothfish in SSRUs of Subarea 88.1 in the Ross Sea
Abstract: The comparative analysis of fishing and investigations on Antarctic toothfish distribution in the Ross Sea (Pacific Sector of Antarctic) show the complete failure of division of Subarea 88.1 on 12 SSRUs accepted in 2003 and allocation of TACs (quotas) based on the square areas of bottom

Reviewing the age structured production model (ASPM) as an alternative method to estimate the Patagonian toothfish biomass at CCAMLR Subarea 48.3
Abstract: Age Structured Production Model (ASPM) have been proposed and applied for Patagonian toothfish stock assessment at CCAMLR Subarea 48.3. Results obtained from this model, presented in the last meeting of WG-FSA-SAM held in Yokohama (Japan), show acceptable fit with standardized CPUE
