The fundamental development of Aquaculture, a branch in agriculture, is in need of using novel techniques. Among the introduced techniques, using beneficial bacteria or probiotic is done with aims such as optimizing physico-chemical factors of water used in aquaculture system, optimized use and the enhanced efficiency of water and also promotion of growth performance of water animals. The Cultivable fishes for securing country’s protein, have very nutritional and economical importance. The development of cultivation system of these fishes can have a very important role in the promotion of fundamental aquaculture of our country. Accordingly, isolation of probiotic bacteria from the gut of cultivable Fishes and using commercial products of these probiotic bacteria, as an important strategy via biological control and enhancement of growth, in cultivation system, could have a very significant role in attaining the mentioned aims. Several researches including some of which by the researcher indicated that some of the probiotic bacteria as a live bacterial supplementation with diet and straight use in water cultivation environment caused ecological adaptation, promotion of fish production, and microbial optimization of water cultivation environment. In fact by having microbial management in using beneficial bacteria, the ability of the host water animal in ecological adaptation with cultivation environment is increased and the optimized exploitation of water resource is promoted. Thus the possible use of water resources was obtained and production efficiency was increased. The results of different researches showed that microbial control and introduction of beneficial strains of bacteria were efficient to increase ecological adaptation, survival, and fish growth performance. It can also be suggested as a strategy for the enhancement and development of fundamental aquaculture in country and beneficial use of water resources.
