Summary

Aquaculture: the ecological issues is written by an international team of researchers. Their aim has been to give an accessible account of the scale and diversity of aquaculture and the impact that it has on habitats and ecosystems throughout the world. It deals with the culture of carp and oysters, catfish and crayfish, salmon and tiger prawns. Written by an international team of researchers. Provides an accessible account of the scale and diversity of aquaculture and the impact that it has on habitats and ecosystems throughout the world Controversial topics such as habitat loss, the introduction of alien species, genetic pollution by escapees from fish farms and spread of disease from farmed to world populations are covered Focuses on how effects of these problems have been ameliorated and looks to a future where improved technology, better regulation and integrated resource management can combine to make the industry more sustainable
