The anticipated empirical consumption level of a target (prey) species by its predators is an important variable when implementing the constant biomass escapement strategy in fisheries management. For a single predator, the projection of empirical consumption will depend, among others, on projected distribution in space–time of the predator, degree of predator overlap with prey, and considerations of fluctuating environmental...

The application of data storage tags bears the potential for a quantum leap in the research on fish migrations, because not only first‐capture and recapture positions are known, but at least theoretically, the migration path during the period at large can be reconstructed. Position, however, cannot be measured directly but has to be estimated using the available data on light, temperature, pressure and salinity. The reconstruc...
