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.

Mature ecological criticism of agricultural policies is not easy: targets agreed in Biodiversity Action Plans must be achieved within a framework of agricultural and economic policies. Developing a balanced solution is the essence of sustainability. Until recently the hidden costs of high-production systems on biodiversity has been ignored.This booklet identifies some of the hidden costs of unsustainable production, and also considers examples where conservation management has failed. The authors argue that sustainable land management is possible, and that conservation and production interests can be satisfied. They go on to show how a sustainable approach can be applied throughout Europe. The approach adopted is the one that has underpinned the development of the European Union Biodiversity strategy and is becoming a compelling force for change in Europe's decision-making processes. Land managers and planners, ecologists and agriculturalists will, in particular, find this booklet an invaluable resource. However, it will also appeal to those with a more general interest in the issues of land management.
