Abstrak: Cirata Reservoir was built with the main function as hydropower and for fisheries floating net cages (KJA). A large number of cages will increasing amount of feed and will impact the discharged waste into the waters of the reservoir. Wasted feed will increase the burden of sedimentation and improve water enrichment. Increased of enrichment can be seen from the loading of phosphor element. This study was conducted from January to March 2013. Species of fish that are reared Common carp (Cyprinus carpio) with the rear period for 4 months. The fish were fed with a pellet with 2:1 of FCR. The content of phosphorus in CF feed is 5.58% and at 3.38% for PL feed. The calculations showed that the amount of phosphorus loads from floating net cages for CF feed is 104.6 kg per ton of fish and for PL feed is 60.6 kg per ton of fish. If the common carp floating cages that fed by CF was added a second layer of tilapia net, it will release phosphorus 95.6 kg per ton of fish, whereas the PL of 51.6 kg per ton of fish. With the rear of tilapia in the second layer nets can reduce the release of phosphorus by 9%.

Judul: Pelepasan Fosfor dari Keramba Jaring Apung Ikan Bawal (Colosomma macropomum) di Waduk Cirata.
Abstrak: Waduk Cirata start to functioned for fishery of floating net cages activity since 1988. One of the main commodities at Waduk Cirata is Black Prompet. It is one of the most fish to consume. Feeding with high Food Conversion Ratio (FCR) lead to high residual feed that accumulated at the base. Moreoverthe content of Phospor (P) at artificial feed was high enough to affect the height of the element P to waters causing eutrophication. This research aimed to estimate the total of P content from Black Pomfret’s floating net cages to environment and to estimate the optimal of carrying capacity at Waduk Cirata for the development of floating net cages to eco-friendly. This research was conducted in Waduk Cirata, West Java from January to March 2013. The release of total P was use JT’s feed is 12.95-12.93% of the weight of the fish and the feed given during maintenance while the SP’s feed is 6.24-6.58% of the weight of the fish and the feed given during maintenance. Carrying capacity was increased when using a feed with a low content of total P. Carrying capacity was obtained using JT’s feed, use 1 layer of net are 18 447 tonnes of fish/ growing season (18 400 plots KJA) while the 2 layer nets are 18 945 tonnes of fish/growing season (18 900 plots KJA).
