1. PRELIMINARY RESULTS OF THE EXPERIMENT ON DEFINITION OF ANTARCTIC KRILL MORTALITY RATE IN FISHERY

   Abstract:  Two successful experiments on definition of Antarctic krill mortality have been carried ... . Approximately 230 to 130 kg of krill are percolated and punched through per an hour of trawling if the average ... catch per an hour of trawling is about 8 tons and towing speed is 2.6-2.7 knots. The key parameters of ... trawling which influence the value of the Antarctic krill mortality rate are: the trawl configuration and ...

7. 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 ...
