Further krill-predator model calculations
Antarctic fur seal dataset. These calculations are extended here. The level of krill fishing intensity ... required to halve the fur seal population (γhalf) is between 0.08 and 0.09, slightly lower than that ... estimated previously. Tests of the estimation procedure indicate that γhalf estimates are likely to be ... biased upwards. The estimator is not robust to incorrect specification of the form of the functional ...
