This review clarifies how biotechnology may be applied on treatment of fish industry effluent to obtain biomass, and also, how this biomass can be applied as a fish food supplement. Currently, with the intensification of aquaculture has been occurrence of parasitic and bacterial outbreaks diseases that economically devastate the fish farming. Thus, arising problems related to inconsistent and incorrectly use of products such as antimicrobials and disinfectants applied in order to control mortality and avoid huge economic losses. To circumvent these obstacles of indiscriminate use of unregistered substances and in order to control the emergence of fish diseases, the use of immunostimulants and vaccines has been shown to be effective as prevention methods besides safety. Some substances can act as an immunostimulant and influence the responses of the fish immune system and its productive performance. Rubrivivax gelatinosus is a gram negative bacterium, purple phototrophic, anaerobic with movement by flagellum which depollute industrial effluents because it uses organic carbon as the main carbon source for growth, thereby, contributing to the removal of carbon and nitrogen from the water. Furthermore, this bacterium provides a biomass with a high nutritional value because it contains a high amount of protein and carotenoid of spheroidene class, considered potent immunostimulant due to its antioxidant action. The use of this bacterium optimizes the fish supply chain, renewing the polluted wastewater, and also gives us by the biotechnology employed, a biological mass immunostimulatory for use in aquaculture itself
