Abstract

WIDYANINGTYAS KUSUMAWARDHANI. Different Stocking Densities of Nile Tilapia (Oreochromis niloticus) in Polyculture Systems on the Growth and Survival of Gourami (Osphronemus gouramy) (Supervised by MOCHAMAD SYAIFUDIN). Polyculture is a cultivation system of more than one type of fish in one cultivation environment to optimize the use of feed, water and land. The purpose and use of this study were to determine the survival, absolute length growth, absolute weight growth, and maintenance of water quality with different stocking densities in the polyculture system of gourami and tilapia. The study was conducted using a Completely Randomized Design (CRD) with 4 treatments and 3 replications. The treatments given were a fixed stocking density of gourami, namely: 19 gourami m-3 (P0), and different stocking densities of tilapia, namely: 19 gourami m-3 + 6 tilapia m-3 (P1), 19 gourami m-3 + 13 tilapia m-3 (P2), and 19 gourami m-3 + 19 tilapia m-3 (P3). The results showed that differences in tilapia stocking density in polyculture systems had a significant effect (p<0.05) on absolute growth in weight and length, survival, and water quality of the maintenance media. The best treatment was P2 with a tilapia stocking density (13 fish m-3) which resulted in absolute weight growth of gourami (2.04±0.03 g) and absolute length growth (2.21±0.03 cm), fish survival (95.00±2.65%). Water quality during the study was within the optimal range for gourami survival and growth.. Keywords: absolute growth, gourami, nile tilapia, polyculture.
