In view of this, an instance of total drying up of the lagoon observed during 1987 is documented and recorded. The ecology of the lagoon is influenced by two principal climatic condition.. When the rains cease, summer prevails and the barmouth closes, thus cutting off freshwater, salinity reaches as high as 73 to 93 %0. Run off water from the land accumulates in the lagoon, the bar gets opened, the lagoon water becomes brackish and salinity values became low (25-33 %0). Due to the existing single bar mouth and under the climatic conditions prevailing, capture fisheries as well as culture projects can be undertaken in the lagoon only from about October till the following March.
