The fundamental constraint in any flow-through catfish production system — whether in an earthen pond or a concrete tank — is water. You can only stock as many fish as…

Dissolved oxygen gets the most management attention in catfish farming because its consequences are fastest — an oxygen crash kills in hours and is impossible to miss. The four parameters…
Of all the water quality parameters that commercial catfish farmers must manage — pH, ammonia, nitrite, temperature, turbidity — dissolved oxygen is the one that kills fastest. A pond or…
Plumbing and water engineering are the infrastructure that determines whether a catfish farm’s water quality management is easy or perpetually difficult. A correctly engineered water supply system delivers the right…
Site selection failures are the most expensive failures in commercial catfish farming because they are permanent. A wrong genetics decision can be corrected by restocking. A wrong feeding program can…
Production system selection is the second most permanent decision in catfish farming — following site selection, it determines the physical infrastructure within which every subsequent operational decision is made. The…
Every management decision in commercial catfish farming has a biological basis. The stocking density that allows African catfish to be held at 150 fish per cubic meter in a concrete…
Site selection failures are the most expensive failures in commercial catfish farming because they are permanent. A wrong genetics decision can be corrected by restocking. A wrong feeding program can…
Species selection is the first and most permanent decision in commercial catfish farming. Every subsequent decision — pond design, stocking density, feed formulation, water quality targets, harvest timing, and market…
EXECUTIVE SUMMARY A national shift to 100% organic free-range egg production in the UK would generate 2,316,000 tonnes of CO₂ equivalent (tCO₂e) annually—nearly twice the 1,184,000 tCO₂e emitted by an…
