Aquaculture is the science of cultivating aquatic animals and plants in fresh or marine waters. It is the extended version of fishing, derived from the fact that harvests of wild sources of fish and other aquatic species cannot keep up with the demand of an increasing human population. Amplification of aquaculture can result in less concern for the environment and therefore, the first prerequisite for sustainable aquaculture is clean water. However, poor management of aquatic species production can alter or even destroy existing wild habitats, increase local pollution levels or negatively impact local species. Keeping this in mind, aquatic managers along with scientists are searching for modern and more efficient solutions to various issues regarding fish farming. This book offers recent research outcomes on the relationship between aquaculture and environment, and consists of case studies from all over the world with the goal of improving and performing sustainable aquaculture.
