Description
Book Synopsis* Focuses primarily on the issues surrounding environmental sustainability of shellfish aquaculture. * Provides key background on the parameters needed for new sitings and expansion of existing aquaculture operations, habitat management, and potential restoration.
Trade Review"While it may be intended for policy makers, and we would all support her in this aim, it will clearly be an essential addition to university libraries, a must-have for shellfish researchers and there could also be good reason for shellfish farmers to think about getting hold of a copy, since it is one way to feel extremely positive about what you do - and supported by real hard science information!."
