Aquaculture: An important consideration in sustainable aquaculture

Fisheries production is closely tied to man's treatment of the environment. The effects of pesticides and high siltation rates from agriculture and urban developments have caused the declines of many fisheries around the world. Most historical fisheries are at or beyond their maximum sustainable yield. However, some gains in production can be obtained from revitalizing natural systems and habitats. This can only be done by managing the environment, and man's activities relative to his environment, and following the concepts of sustainability. This may require preservation zones adjacent to natural waterways, runoff collection ponds below agriculture and urban development, control of the use of pesticides and herbicides, and other control measures.
