According Afrianto and Liviawaty (2003)

According Afrianto and Liviawaty (2003) polyculture system is maintained on a pool of various types of fish require different kinds of food so that each type of fish will not compete for food. To increase the productivity of pond fish farmers apply this polyculture system.Polyculture fish farming requires certain techniqueDAUNPOKER.NET AGEN POKER DOMINO ONLINE INDONESIA TERBAIK TERBESAR DAN TERPERCAYAs and management. To get a good harvest we need to pay attention to the stages in fish farming. These stages starting from the stage of preparation, stocking phase, phase maintenance, and harvesting stages. In maintenance, we need to pay attention about feed management, water quality, and monitoring of pests and diseases of fish. By maintaining each stage in fish farming, then we can maximize the productivity of fish and produce high survival rate. Selection of species or kultivan in polyculture cultivation is also becoming a critical success factor polyculture cultivation. Or kultivan species to be cultivated habitats should have a different life. Therefore, the purpose of farming polyculture pond is to maximize the carrying capacity (carrying capacity) by utilizing the entire water column in the pond.
 Raising catfish and red tilapia cultured in one case is one example of polyculture farming. The selection of these two species because the catfish is a fish that like to live in the bottom waters while red tilapia is a fish that like to live on the surface so that the use of both of these species is expected to optimize the pool of potential carrying capacity (carrying capacity) by utilizing the entire space in the pool.
Polyculture system has the advantage, among others, (Afrianto and Liviawaty, 2003):1. The natural food available in the pond can be effectively utilized by fish, so there is no longer a natural food that is wasted,2. Use of land to be efficient, because in the same broad fish can be maintained with a higher density,3. Overall, production ponds will increase because the number of fish that are kept in the pool more,4. Production of each species of fish will be higher when compared with the results with the monoculture system maintenance. Allegedly there has been an increase in the production of natural food as a result of the process of fertilization by fish waste,5. Levels density of each species of fish in polyculture systems are generally the same or slightly lower when compared to the density of the species in monoculture. This is possible because each fish has a kind or a different dining areas.
