Download or read book An Updated World Review of Interactions Between Marine Mammals and Fisheries written by Simon P. Northridge and published by Food & Agriculture Org.. This book was released on 1991 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent information on marine mammal - fishery interactions is reviewed. A species by species approach is taken for each of the major marine fishing areas of the world. Most recent studies have been devoted to the accidental entanglement or mortality of marine mammals in fishing operations. Several species or populations of marine mammal may be threatened with extinction or severe depletion from such interactions. Most of the fisheries involved are gillnet fisheries. Relatively few recent studies have addressed the possible competitive interactions between marine mammals and fisheries for food and fishery resources.
