An idea to incorporate potential recruitments in the krill density model
in the model, dramatic variation of densities after 1994/95 season could not be clearly explained ... involved uncertainties of age 1 krill. Present document improves the model by taking the uncertainties in ... to account, and assuming a reasonable mortality. The model suggested that if we expect the currently ... accepted values of mortality M (0.8-1.0), the potential proportional recruitment should be larger than the ...
