Bottom Soils, Sediment, and Pond Aquaculture formatIsbn:Softcover - 9781461357209 While this book partly buildsAquaculture pond managers measure water quality variables and attempt to maintain them within optimal ranges for shrimp and fish, but surprisingly little attention is paid to pond soil condition. Soil water interactions can strongly impact water quality, and soil factors should be considered in aquaculture pond management. The importance of soils in pond management will be illustrated with an example from pond fertilization and another from aeration.
