COMMENTS ON KRILL BIOLOGICAL SAMPLING WITH REGARDS TO SISO OBSERVERS ON KRILL FISHING VESSELS

In this paper, the authors consider the efficiency of observer krill samples in the context of Scientific Observer’s Manual to sample 200 individuals every 3 or 5 days regardless of the number of hauls and the catch values per haul and per day (CM 51-06). The authors have used data obtained on-board Russian vessel Komandor operated in Subares 48.1 and 48.2 during season 2024. 

 Our results have shown the necessity to evaluate the effective krill sample size required to estimate key parameters using scientific observer data on board krill vessels and implement changes to the data collection protocol for krill sampling.
