A PROPOSAL TO COMBINE CONSERVATION MEASURES 22-01 (NEW FISHERIES) AND 22-02 (EXPLORATORY FISHERIES)
Abstract: Because the requirements to participate in a New or Exploratory Fishery are ... substantially different, the United States proposes to combine the two measures so that needed information and ... data are gathered and submitted to CCAMLR in all years of the fishery. The proposed CM attempts to ... ensure a minimum change in existing text which has already been agreed by the Commission in the existing ...

KPFM2, be careful what you ask for – you just might get it
Abstract: We have substantially revised the krill-predator-fishery model that was presented to ... the WG-EMM in 2005. The new version of our model is called KPFM2, and we have addressed all four of ... the changes which the WG-EMM indicated would be required to use the model for providing advice on the ... allocation of catch among the SSMUs (i.e., add seasonality, consider alternative movement hypotheses, add ...

Maximum entropy reconstruction of stock distribution and inference of stock density from line-transect acoustic survey data
distribution from acoustic line-transect data. MaxEnt is founded on the bedrock of probability theory and ... allows the most efficient possible use of known data in the inference process. The method takes explicit ... account of spatial correlation in the observed data and seeks to reconstruct a distribution of density ... across the whole survey area that is both consistent with the observed data and for which the entropy is ...

APPLYING A TS-PROBE FOR MEASURING ANTARCTIC KRILL (EUPHAUSIA SUPERBA) TARGET STRENGTH IN SITU: PROCEDURES AND DATA ANALYSIS
Abstract: A submersible multifrequency acoustic TS-probe was used for measuring the target ... strength of Antarctic krill in situ at short range. The experimental methods, procedure for data retrieval ... operating at 38, 120 and 200 kHz is installed in the probe, connected to three pressure resistant ... transducers with 7o half power beam opening angles. The orientation of the probe was monitored with sensors ...

Distribution and population structure of Dissostichus eleginoides and D. mawsoni on BANZARE Bank (CCAMLR Division 58.4.3b), Indian Ocean, Antarctic
maturity condition for Dissostichus eleginoides and D. mawsoni were investigated on Banzare Bank, using the ... fishing season. D. eleginoides was mainly caught in the shallower bank <1000 m, while D. mawsoni was ... mainly caught in the deeper slope >1500 m. The separation of the two species by depths may be related ... to the physical intolerance to the cooler temperature by the lack of antifreeze for the former ...

Beach debris survey Signy Island, South Orkney Islands 1999/2000
Abstract: During the 1999/2000 austral summer the tenth annual beach debris survey was carried ... from three study beaches. The debris was counted, measured and classified by type,material, mass and ... size categories. A total of 55 items weighing 10.78kg was collected. The number of items was 35% less ... than 1998/99, and the second lowest ever recorded. The total mass of the waste recovered has decreased ...
