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 ... observation error. The parameters of the model were estimated by the Markov chain Monte Carlo (MCMC) method in ...
