Description	The fish production in aquaculture is growing from year to year. Capacities of current aquaculture facilities are limited. The need of intensification of this old facilities and building new intensive facilities is obvious. The high intensity of fish production generates some questions. Could reuse of water affect fish growth, welfare, health or quality of final product? A lot of research was performed for this issue but just a few works compared water reuse systems (RAS) versus flow thru systems (FTS). A problem with CO2 oversaturation was solved by shallow diffusers. Fin erosion seems to be a problem of high stock density and system hygienic but it is not conjoined directly to water reuse. A few papers were written about biochemical blood stress markers but it was mostly aimed to acute crowding or changes were found at extreme stock densities over 124 kg.m3 for rainbow trout and 70 kg.m3 for sea bass. The fish are able to accustom to increased noise produced by RAS equipment very fast so it don't affect fish negatively. I haven't found prove of main water reuse to fish influence in the available literature. All results indicates that if the ecological parameters are kept in natural range for the fish reared in RAS, there is no negative effect of water reuse on fish.
