Influence of daylight and incubation interval on water column respiration in tropical fish ponds.

Abstract: Water column respiration (WCR) was measured in dark BOD bottles for 2, 4 and 8 h intervals during 22 h periods in two 1000 m2 […]

Tilapia Yield Improvement Through Maintenance of Minimal Oxygen Concentrations in Experimental Grow-Out Ponds in Honduras

Abstract: Tilapia yields and water quality were compared in 1000-m2 grow-out ponds that were unaerated, or aerated beginning at 10 or 30% of oxygen saturation. Tilapia […]

Effects of urea application, aeration, and drying on total carbon concentrations in pond bottom soils

Abstract: Aerated ponds did not accumulate as much carbon in bottom soils as control ponds. Application of urea to manured ponds did not accelerate carbon loss […]
