4.2.9.3 Amaravathy Reservoir (Tamilnadu)
This is also a productive small reservoir (850 ha). It gave a high fish yield earlier (500 kg/ha) with accidental introduction of tilapia (1957-58). Subsequently, when the reservoir was regularly stocked with major carps, the tilapia fishery declined (60 to10%). There was establishment of major carps and dominance of catla followed by rohu and mrigal. |
