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 ... krill length and number of bycatch fish were analyzed by using a hierarchical Bayesian model composed of ... krill length model, some parameters did not converge well in the bycatch fish model. The interaction ... between month and sub-areahas large effects on krill length. Krill length varies among cruises, but there ...
