1. A RISK ASSESSMENT TO ADVISE ON STRATEGIES FOR SUBDIVIDING A PRECAUTIONARY CATCH LIMIT AMONG SMALL-SCALE MANAGEMENT UNITS DURING STAGE 1 OF THE STAGED DEVELOPMENT OF THE KRILL FISHERY IN SUBAREAS 48.1, 48.2, AND 48.3.

   Abstract:  We used Foosa and the reference set of parameterizations developed by Watters et al ... . Implementation of Fishing Option 2 (using the subdivisions reported here) will require that the fishery mostly ... operate in pelagic SSMUs. Up to harvest rates of 0.5 x γ, this subdivision is unlikely to reduce predator ... populations to 75% or less of the abundances that might occur in the absence of fishing; the risks of such ...

2. Stable isotope analysis of tissue samples to investigate trophic linkages of Antarctic toothfish (Dissostichus mawsoni) in the Ross and Amundsen Sea regions

   Abstract:  Stable isotopes of carbon and nitrogen (δ 15 N and δ 13 C) in Antarctic toothfish ... (Dissostichus mawsoni) muscle were measured to study the trophic connections of Antarctic toothfish in the Ross ... samples each of four by-catch species (grenadiers, icefish, moray cods and deep-sea cod) were also ... analysed, but only from the Ross Sea region. Appropriate corrections were made to account for the effect of ...

3. Estimating the biodiversity and distribution of the northern part of the Kerguelen Islands slope, shelf and shelf-break for ecoregionalisation: benthos and demersal fish

   , with 409 operations at depths ranging from 100 to 1000 m. The aim of SKALP and POKER was to investigate ... . However, few of them have collected benthic organisms. Between 1961 and 1970, numerous surveys were ... limited areas. However, they collected numerous specimens and led to a first estimate of the local ... biological diversity. The richest cruises for the quantity of benthos collected are MD03 and MD04 (1974 and ...

5. A BALANCED MODEL OF THE FOOD WEB OF THE ROSS SEA, ANTARCTICA

   Abstract:  We present a quantitative food web of the Ross Sea as a step towards investigating ... ecosystem effects of the fishery for Antarctic toothfish (Dissostichus mawsoni). The model consolidates ... quantitative information on trophic links across all the major biota of the Ross Sea and tests for data ... consistency. The model has 38 trophic groups and is balanced in terms of annual flows of organic carbon in an ...

6. Dates of spawning of Antarctic euphausiids

   Abstract:  The paper considers the determination of time of breeding of five species of Antarctic ... Euphausiids. The original and literature data on age composition of larvae gave the possibility to calculate ... the dates of the beginning, termination and periods of high and the most intension of spawning. In the ... waters of different origin and on different latitudes euphausiids begin to spawn in a usual succession ...
