A first experiment on cage culture of Catla catla in back water of Shankar Sagar reservoir, Vishnupuri Project Dist. Nanded, Marathwada (Maharashtra)

Abstract

This is the first attempt for cage culture in Marathwada Maharashtra State, Results of the experiments showed that Marathwada can be potential area for cage culture. The growth performance of Catla catla,  in natural and in  artificial feeding cages in terms of final weight, weight gain percentage, specific growth rate (SGR %), Daily growth rate (DGR), survival rate and total production was described in text. Their final weight was 6.25±0.62, 10.39±4.18, 22.06±8.14, 38.69±20.2, 64.73± 17.7 and 111±17.2gm for I, II, III, IV, V and VI th months respectively in natural feeding cage. Their final weight was 7.98±1.23, 15.27±3.75, 42.53±9.23, 84.83±19.85, 182.96±21.14 and 260±11.77 gm recorded in I, II, III, IV, V and VI th months respectively. In natural feeding cage, mean weight 111 gm of Catla catla was attained whereas in supplementary feeding cage 260 gm was recorded in 180 days of culture period. The total fish production of Catla catla in 180 days in cage culture with natural feeding was 7.8 kg. Whereas it was 20.3 kg in supplementary feeding cage
