Abstract

A comparative research study was executed to assess the production and cost-benefit return from Indian major carp (IMC) and GIFT tilapia, Oreochromis niloticus.The research study was operated with two individual tank size of 0.4 ha each (T1 & T2) for a period of 9-10 months from September, 2018 to June, 2019 with a selected farmer of Cuttack district, Odisha state.The present study focused on water quality parameters, production and cost-benefit analysis.An Interview with a pre-tested questionnaire was conducted for data collection during April 2020.In T1 & T2, the mean value of temperature varied 26.3±4.56&27.7±6.5;pH 7.5±0.55&7.5±0.35;DO 6.07±1.35&5.3±0.51;Transparency 27.71±0.86& 29.29± 0.81; Alkalinity 100.4±12.8& 98.3±14.2 and Ammonia 0.55±0.05&0.58±0.04respectively.The study tanks were demonstrated by World fish through Dept. of fisheries, Govt. of Odisha sponsored project.In T1, advance fingerlings of Catla catla 9-12cm & 18-23g, Labeo rohita 10-12cm & 18-24g and Cirrhinus mrigala 8-11cm & 15-19g were stocked with density10,000/ha with catla, rohu & mrigala in the percentage ratio of 40:30:30 respectively on 3rd September 2018, whereas in T2, average size of GIFT mono-sex tilapia seed 6-7cm &7-9gm were stocked with density 16,000/ha on 15 th September 2018.In T1 & T2 (>91 & 93.7%) the survival rate and the final harvest done in June 2019.The total harvest of 8457.5 kg/ha was done in T1; where as in T2, total harvest was 20,000kg/ha with cost benefit ratio of 0.81 in case of IMC poly-culture and 1.22 in case of GIFT mono-sex tilapia.
