Abstract:
This research was carried out at swamp area in Jeruju village, Sungai Kakap District, West Borneo Province in 2006. The red mono sex nilas were cultured in swamp pond consisted of six nets. Every net has 2 x 1 x 1 m dimension.The research was arranged by Factorial Randomized Block Design. First factor was density population which had 1O, 15, and 20 nilas per meter square. Second factor was method of feeding which consisted of self feeder and broadcast feeder. There were six combination treatments and three replications. Parameters were observed namely daily growth rate,feed consumption ratio (FCR), and survival rate (SR). Water quality was observed as complement data.The feed has 30% protein content. The result showed that the 15 nilas/m2 produced the best growth namely 220.2 to 236 gram and the SR is 99%. Financial analysis showed that the 15 nilas/m2 and self feeder had 1,572,500 rupiahs of benefit and R/C was 1.40. While the broadcast feeder had 1,291,500 rupiahs of benefit and R/C was 1.32.
