A model at the level of the foraging trip for the indirect effects of krill (Euphausia superba) fisheries on krill predators
Abstract: 1. Although the development of fisheries for krill in the southern oceans has prompted ... with slopes less than 1; that is, reductions in reproductive success and parental survival are linear ... functions of krill catch but not 1:1. The reductions in offspring and parent survival are mainly determined ...
