Abstract
Pond bottom soil plays an important key role in regulating the concentrations of nutrients in the pond water, Shrimp ponds are the dynamic and complex ecosystem, it will produce the tragetable production of the nutrient cycle and waste decompositions are properly managed. Research tells that, in semi-intensive shrimp farming system added phosphorus accumulated about 63.5% and 38% of the total nitrogen in the sediment. The higher concentration of organic and inorganic nutrients in bottom soils of older compare to newer ponds. Salt water used for shrimp culture contains higher concentration of sulfate possible for sulfide production; the sediment accumulating in shrimp ponds is the black color with smell of H2s. The removal of organic sediments by digging is expensive, and natural dry-out combined with liming and occasional sediment removal should be investigated as a less expensive and more environment eco-friendly alternative to removing sediment after each crop. The success of aquaculture can be assured by selecting a site with suitable soil and a high quality water supply, it is essential to understand the pond soil and water characteristics and their optimum requirements to increase the productivity of the ponds. This review discusses the pond bottom management and soil treatment techniques for improving the condition of pond soils. Application of these techniques can enhance soil condition and water quality, improve production efficiency, and prolong the useful life of ponds also this study strongly recommends to the shrimp farmer to concentrate in each and every culture likely to enhance the bottom soil by adding some extra nutrient to the soil.
