Aquaculture is of great economic, social and environmental importance, and researchers are continually seeking new and more sustainable practices. This book seeks to inform the reader of current thinking on topics in aquaculture with a focus on sustainability. In the first part, the relationships between aquaculture and the environment are examined. The contributors present their findings on topics including the efficacy of a new pilot-scale wastewater treatment on aquaculture effluence, and the metals in crawfish. Part two reviews sustainable aquaculture techniques. Topics include the use of yeasts as probiotics in fish aquaculture, the application of biological agents in abalone aquaculture, and the use of probiotic bacteria against infection in shellfish and fish aquaculture. Part three, finally, examines recent advances in fish farms. Here, new findings are presented on topics including the environmental effect of using polluted water in new/old fish farms, and a study from Greece of bacteria isolated from diseased wild and farmed fish. The contributors draw on extensive experience worldwide, and all chapters are supported by reviews of the relevant literature, ensuring this is a relevant, reliable source of current knowledge and new ideas.
