Hydrogen sulfide toxic, but manageable
Hydrogen sulfide, which can form in pond bottom sediment, is toxic to aquatic animals because it interferes with reoxidation of cytochrome a3 in respiration.
Responsibility
Shrimp pond preparation crucial for production, disease prevention
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.
Responsibility
Sediment, water sampling in aquaculture
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.
Responsibility
Sediment microbiology, management
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.
Responsibility
Organic matter in pond bottom sediment
Organic matter – including fertilizers, unconsumed feed and feces of culture animals – settles to pond bottoms, often with a negative impact on water quality.
Responsibility
Sediment accumulation in channel catfish production ponds
We sampled pond bottom sediments from 45 commercial channel catfish ponds that were in production for 14 days to 21 years.
