Preventing diseases is a major concern in shrimp farming. Pond preparation focuses on avoiding the carryover of disease organisms from one crop to the next.
Hydrogen sulfide, which can form in pond bottom sediment, is toxic to aquatic animals because it interferes with reoxidation of cytochrome a3 in respiration.
Simple tools can take water and sediment samples to monitor quality variables in aquaculture ponds. Water surface samples provide limited information, while water column sampling delivers more specific data.
Sedimentation increases organic matter concentration in pond bottom soil. Particles originating from mineral soil and organic matter that do not float or dissolve settle to the bottom.
