Marine mammal-fisheries interactions [competition]

Marine mammals and fisheries interact in many ways. Marine mammals become entangled in nets, causing damage but often drowning themselves. They compete with fishermen for the same species of fish, and are carriers of parasites which may reduce the value of fish catches. The extent of these interactions are increasing with the development of new fisheries, and the recovery of some stocks, especially of seals, from the effects of earlier over-exploitation.
