1. Krill density, biomass, proportional recruitment and recruitment index in the elephant island region during the period 1977 to 1997

   Abstract:  The Elephant Island long-term data set was updated for krill density and proportional recruitment. Krill biomass (from net sampling surveys) and absolute recruitment are introduced as additional indices for this time series. New survey results of the past two seasons indicate a very

3. Escapement of elephant seal prey in the Heard Island fishery for Dissostichus eleginoides

   Abstract:  The Patagonian toothfish, Dissostichus eleginoides, has been reported as prey of Elephant seals in the Heard Island region. A question was raised at SC-CAMLR-XV concerning what affect the fishery for toothfish in Division 58.5.2 might have on the abundance of the age classes of toothfish

4. A comparison between the estimated density of krill from an acoustic survey with that obtained by scientific nets on the same survey

   Abstract:  This work presents the initial comparative analysis of acoustic and net haul krill density estimates for the RMT 8 oblique (0 to 200m depth) trawls conducted during January-March 1996 as part of a hydroacoustic biomass survey for Antarctic krill in CCAMLR Division 58.4.1. The acoustic

5. Workshop on International Coordination (14 to 18 July 1997)

   Abstract:  The 1997 Workshop on International Coordination was convened by Suam Kim (Korea) at 0900 on 14 July 1997 at the Southwest Fisheries Science Center, La Jolla, California. In attendance were Sung-Ho Kang (Korea), Hyungmoh Yih (Korea), Mikio Naganobu (Japan), So Kawaguchi (Japan), Volker

6. Bias in the estimation of krill yield from using a deterministic formulation of the median unexploited spawning biomass

   Abstract:  Two Monte Carlo simulation models are currently available to CCAMLR for estimating krill yields according to decision rules that relate spawning stock status to the median unexploited spawning biomass, SB0. The first model has been developed specifically for krill, the krill yield model,

7. Net sample validation of acoustic techniques used to identify and size Antarctic krill

   Abstract:  Acoustic surveys to estimate krill biomass require that sound backscattered by krill be identified and distinguished from all other types of backscatter. Traditionally this has been achieved by sampling characteristic types of acoustic target with nets. More recently partitioning of

8. Variation in the distribution of Antarctic krill Euphausia superba around South Georgia

   Abstract:  Between 1980 and 1997 British Antarctic Survey carried out 11 cruises in the region of South Georgia. Here we summarize the length-frequency distributions of krill caught on each of these cruises and look particularly at differences between krill taken from the eastern and western ends

9. Krill biomass estimates for South Georgia, December and January 1996/97

   Abstract:  Stratified random acoustic surveys, each comprising 10 parallel transects, were conducted within two 80 x 100 km areas over the shelf-break to the north-east and north-west of South Georgia during December/January 1996/97. Netting suggested that the mean lengths of krill within the

10. Krill biomass and distribution in Subarea 48.2 during summer 1996

    Abstract:  The results of hydroacoustic survey of krill biomass assessment in Subarea 48.2 adjacent to Coronation Island, carried out in February-March 1996 in Russian RN "ATLANTNIRO" are presented. Taking in account close relation of krill and oceanographic structure of waters and
