Fishing provides food, income and employment for millions of people. However, fishing has environmental costs that threaten rare species, marine ecosystems and the sustainability of the resource.Based on the research expertise of leading scientists, Commercial Fishing: the Wider Ecological Impacts provides a lively, timely and accessible account of fishing activities and their impacts on marine habitats, biodiversity and species of conservation concern. It covers fishing methods that range from trawling in the Antarctic to fishing with dynamite in the tropics. The authors show how habitats such as the muddy sea beds of the deep sea, kelp forests and coral reefs are affected by fishing and how birds, mammals, turtles and sea snakes both suffer and benefit from fishing activities. They also look to the future, highlighting ways to make fishing gear 'environmentally friendly' and asking whether marine reserves will improve conservation.

South Georgia is rich in wildlife and spectacular scenery, and it is a prime destination spot on most Antarctic tours. This beautifully illustrated field guide depicts the birds, mammals, insects, flowering plants, and other vegetation found in this unique part of the world. It features 368 full-color photographs of more than 180 species, including 65 species of birds, 20 species of sea mammals, nearly 60 species of insects, and more than 40 species of flowering and nonflowering plants. Detailed species accounts describe key identification features, with information on status, behavior, threats, and distribution. This one-of-a-kind photographic guide also includes introductory chapters on South Georgia's geography, climate, ecology, and conservation. * Features 368 photos of more than 180 species * Covers birds, sea mammals, insects, and plants * Provides detailed species accounts * Includes chapters on geography, climate, ecology, and conservation * The only photographic field guide to focus specifically on South Georgia
