Possible effects of different levels of fishing on krill on predators - some initial modelling attempts
Meeting of the CCAMLR's WG-Kril1 and WG-CEMP in 1992 to address this issue. First. estimates are made ... of the parameters of predator survival rates as functions of krill abundance, by considering a krill ... . Computations based on this model indicate that variability in the annual recruitment of krill results in ... . However, the analyses also raise a number of questions about the proper interpretation of the available ...
