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

Two 1000 m2 ponds stocked with Oreochromis niloticus were used to study water column respiration (WCR) in dark BOD bottles for 2, 4 and 8 h intervals during a 22 h period. The mean WCR ranged between 0.39 mg per litre for 8 h nocturnal intervals to 0.62 mg per litre for 2 h diurnal intervals. It was...

Description
Summary:Two 1000 m2 ponds stocked with Oreochromis niloticus were used to study water column respiration (WCR) in dark BOD bottles for 2, 4 and 8 h intervals during a 22 h period. The mean WCR ranged between 0.39 mg per litre for 8 h nocturnal intervals to 0.62 mg per litre for 2 h diurnal intervals. It was significantly greater during the day than during the night with the lower incubation period giving a higher WCR than the 2 higher periods. At night, the length of the incubation period did not significantly influence WCR. These higher WCR were attributed to a greater availability of photosynthetic respiration substrate.
