| Integrated multi-trophic aquaculture (IMTA) system can increase production of aquaculture with additional economic value in addition to a biological purification of the effluent from the float net cage (KJA). This study aims to evaluate daily growth, feed conversion rate, and survival rate of marine commodities in KJA that are implemented through the IMTA system. This research was conducted in waters of Karang Lebar Semak Daun Island, Seribu Islands, Jakarta, Indonesia. The IMTA model developed is a combination of white shrimp (Litopenaeus vannamei), rabbitfish (Siganus doliatus) and seaweed (Euchema cottonii). The results showed that for 60 days maintenance period of white shrimp cultivated by IMTA system showed better effect than shrimp cultivation with monoculture system. The daily growth of white shrimp, rabbitfish, and seaweed was 0,12±0,001 g day-1, 0.10±0.013 g day-1 and 14.30±4.33 g day-1. The conversion rate of white shrimp feed was 2.73±0.73%, and the survival rate of white shrimp was 71.00±14.53% and for rabbitfish was 84.39±1.00%. The results of this study indicate that IMTA model of IMTA system is more effective in improving the performance of shrimp productivity and visible effects of mutual benefits between organisms incorporated in IMTA system and can be applied as a model of development of sea cultivation that is environmentally sound. | ||
