About this book

Covers 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 wild populations. Attention is drawn to the heavy reliance of the industry on fishmeal and fish oil derived from industrial fishing that in turn impacts on the food supply of seabirds and fish such as cod and haddock. It shows 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.

...a great text. It is brief enough to be readable by students but detailed enough (especially with references) to provide an excellent overview of the topic. Teaching Ecology Group Newsletter, July 2003
