Results of scientific observation in Antarctic krill fishery in 2010/11: II. analysis of variability of krill size and fish by-catch
Abstract: We examined spatio-temporal variability of krill body length and number of bycatch fish ... as variables of interest based on the scientific observer data for the 2010/2011 fishing season. Both krill ... length and number of bycatch fish were analyzed by using a hierarchical Bayesian model composed ... of multistage cluster units (i.e., month, sub-area, fishing gear, flag state, vessel, cruise, and haul ...
