Periodic measuring of water levels in water reservoirs in SriLanka

Credit: Ajith Kumara (SriLanka)

The photos show the official team while carrying out one of the monthly measurement of water level in a water reservoir. Based on the measurements, the estimation of the exposure extent of particular area during a given period is obtained. Hereafter an attempt will be taken to incorporate these data with tilapia breeding behavior.

The boat shown is a non-motorized outrigger canoe (locally called “Oru”) which is used in SriLanka water bodies. The number of fishermen could range from 1-3 persons per boat depending on the size of reservoir, season (rough or calm wind and wave exists); motorized boats in these reservoirs are totally banned.
