4.2.9.1 Bhavanisagar Reservoir (Tamilnadu)
It was constructed across the river Bhavani in Taminadu. Its ichthyofauna comprises 51 species belonging to 11 families. Among them, 18 species contribute to the commercial fisheries. The important species in order of abundance are Labeo calbasu, Cirrhinus mrigala, C. catla, Labeo rohita, Puntius dubius and Labeo fimbriatus among the carps and Mystus aor and Wallago attu among the catfishes. The fish yield is about 250 tonnes. As per a recent report, stocks of L. calbasu and catfishes like W. attu and M. aor were also found to decline, attributed to the dominance of weedfishes. Intensive stocking of L. fimbriatus, though a native fish of Cauvery system, also did not pay any dividends. |
