Abstract
The over-carrying capacity of aquaculture activity caused water quality degradation as impacted by waste loading from uneaten feed and fish metabolism. The need for ecologically friendly technology can diminish the pollutant for sustainable aquaculture activity. SMART Floating Net Cage (FNC) is an aquaculture technology that combines double net and bag collection waste and filtration systems by the plant. The research aims to know the known growth rate and productivity of SMART FNC. The study was done in Jatiluhur Reservoir in February-November 2021 in Pasir Canar Zone. The cage was using have 14x7x5 m in dimensions with a double net. The inner net was divided with a 7x7x3 m dimension for common carp rearing and the outer net with 14x7x5 m for Nile tilapia rearing. The weight of common carp and Nile tilapia seeds were 200 and 150 kg, respectively. The growth rate of common carp and Nile tilapia were 2,4-4,3 dan 2,0-6,3 g/day, respectively, with 1578 and 400 kg/period for harvest.
