The research was done in concrete fishponds owned by the community and the other owned the Laboratory of the Faculty of Fishery of the Christian University of Palangka Raya, Central Kalimantan. The Lais were domesticated coming from the Rungan river of Palangka Raya city. The research was done in March throhh July 2016. The study was conducted in two stages, the first stage of research to engineer Lais fish maintenance environment on plakstik pond and the second stage to engineer the feed so that the fish can adapt and grow. The parameters observed were: fish growth, survival, food conversion and water quality (temperature, DO, pH, depth), as well as the development of Lais fish gonads. The sample of test fish is 200 fish, each pond is 50 tails per pond. The virtues of this study were to engineer the Lais fish feed and adaptation time of the fish in new maintenance environments as well as adaptation to artificial foods that promote the hormonal growth of Lais fish. Innovation of environmental engineering cultivation and adaptation of artificial feed for the development of fish gonad. Lais fish farming technology can be applied by freshwater fish farmers.
