Fisheries

The non-indigenous Oreochromis mossambicus, tilapia fish was introduced here in the 1950s and subsequently this reservoir had highest fish yield in the state by the 1970s. Tilapia now accounts for a major portion of the catch in the reservoir.

s/year of fish from the reservoir. In 1972, a fish yield of 168 kg/ha/yr (168 kg/yr x 931 ha = 156,408 kg/yr. = 156.408 tonnes/yr.) was reported. The Fisheries Department has formed the Amaravathi Nagar Tribal Fishermen Cooperative Society to give tribals fishing rights in the Amaravathi Reservoir. In 2007, fifty tribals who reside at Karattupathi settlement, close to the reservoir, enrolled themselves as members of the society and eight of them have received a fishing licence.

s, also known as marsh crocodiles and Persian crocodiles, are the most common and widespread of the three species of crocodiles found in India. They eat fish, other reptiles, small and large mammals and are sometimes dangerous to humans. Their total wild population here is currently estimated to be 60 adults and 37 sub-adults. Other fish predators here include: Oriental small-clawed otters, Indian cormorants and Indian flap-shelled turtles. The Amaravathi Sagar Crocodile Farm, established in 1976, the largest crocodile nursery in India, is 1 kilometre before the Amaravathy dam site. Many adult crocodiles have been reintroduced from here into the wild. Eggs are collected from wild nests along the perimeter of the reservoir to be hatched and reared at the farm. Many crocodiles of all sizes can be seen basking in the sun and suddenly making a stride or piled up on one another. There are now 98 crocodiles (25 male + 73 female) maintained in captivity here. Three Forest Department personnel manage and maintain the centre.,
