| Abstract |
Growth of fish in ponds is of great potential commercial interest. The purpose of this study is to discuss those aspects of the chemistry , physics, and biology of natural waters which are relevant to the water-quality conditions in aquaculture systems. The basis biogeochemical processes which control the water quality in such fish ponds are examined. Special attention is given to discussing the similarities and differences between seawater and freshwater as they affect the practice of aquaculture. Three case studies of a stagnant freshwater pond, an earthen intermediate-flow seawater pond, and a high flow-rate intensive "Taiwanese" pond are presented. Fish culture systems can be categorized on the basis of flow-rate into three types, low-, intermediate-, and high-flow; each controlled by different basic biogeochemical processes. The implications of such a division are discussed, and some future developments in the field of water quality are presented. |
