A fishery fueled by an illegal trade is putting two species of dolphin in danger of local extinction in Papua New Guinea, according to Jacinta Gigileia Jonathan, a fisheries biologist and marine mammal researcher based there.
Jonathan, a postgraduate research scholar, says her 2019 research project found that that dolphins are ending up as by-catch, that is, species that are caught and die in the course of commercial fishing for another species.
