The freshwater fisheries of Ceylon

Based on our present knowledge a comprehensive account of the freshwater fisheries of Ceylon is given. The material for the present paper comes from data gathered by the authors over a period of fifteen years on the general setup of the fisheries and specific research carried out on a few major aspects of the fisheries. All the previous published work is gathered together. Most of the data available to the authors has been from the Polonnaruwa area, namely Parakrama Samudra and Minneriya tanks and Senanayake Samudra in the Gal-Oya Valley. Studies have also been made on Tilapia mossambica because of its great importance to the fisheries in general.
