Demersal longlines with integrated weight: a preliminary assessment of sink rates, fish catch success and operational effects
Abstract: Conservation Measure # 216 requires vessels fishing in sub area 88.1 + sink longlines at 0.3 m/s to 15 m depth. Sink rates can be achieved by adding external weights to lines or by using lines with weigh integrated into the rope fibres. The sink rates to 15 m depth of 9 mm demersal

Standing stock estimates of finfish biomass from the 2002 Polarstern bottom trawl survey around Elephant Island and the South Shetland Islands (Subarea 48.1) with some notes on the composition of catches taken north of Joinville Island – D’Urville Island
Abstract: Germany conducted a bottom trawl survey aboard R/V ‘Polarstern’ around Elephant Island and the South Shetland Islands in January – February 2002 in close collaboration with the U.S. Antarctic Marine Living Resources Program (AMLR). Information on species composition, biomass, and size

How fast do demersal longlines sink?
Abstract: Longlines that sink fast reduce the time available to seabirds to attack baited hooks and are important in efforts to minimise seabird by-catch in longline fisheries. We measured sink rates in still water of longlines made by Fiskevegn, the world’s leading manufacturer of demersal

Fecundity and size at sexual maturity of the bigeye grenadier (Macrourus holotrachys) at South Georgia (CCAMLR Subarea 48.3)
Abstract: Fecundity and size at sexual maturity were investigated in 486 bigeye grenadier, Macrourus holotrachys caught as bycatch in the Patagonian toothfish longline fishery conducted around South Georgia. Macroscopic and histological investigations revealed that absolute fecundity ranged from

Fecundity and egg size of Lithodid crabs from CCAMLR Subarea 48.3
Abstract: The fecundity and egg size of three species of lithodid crab caught in CCAMLR Subarea 48.3 was examined. Relative fecundity (eggs-g body weight) and egg size was found to differ significantly between species. The highest relative fecundity and smallest egg size was found in Paralomis

Movement and growth of tagged toothfish around South Georgia and Shag Rocks (Subarea 48.3)
Abstract: In 2000 the UK started a toothfish (Dissostichus eleginoides) tagging programme. The aims were to investigate the spatial and temporal movement of fish and to validate growth estimates. Since then approximately 2,260 toothfish have been tagged and released during groundfish surveys and

Notes for identifying the three macrourid species, M. holotrachys, M. whitsoni and M. carinatus in CCAMLR Subarea 48.3
Abstract: Digital pictures and morphological measures are presented to aid CCAMLR observers with the identification of three macrourid species caught as bycatch in the fishery for Patagonian toothfish, Dissostichus eleginoides, in Sub-Area 48.3. Scaling under the snout was used to separate

Information on the spawning season and gonadosomatic indices of Dissostichus mawsoni from Subarea 88.1 in the 2001/02 season
Abstract: Data on maturity, gonadosomatic index (GSI) and length/weight of Antarctic toothfish Dissostichus mawsoni were collected from Sub-area 88.1 in the 2001-2002 season by the New Zealand bottom longline vessels Janas and San Aotea II operating in the Exploratory Fishery. The onset of the
