The aim of this work was to determine the optimum stocking density of Penaeus vannamei cultured in a photo-heterotrophic intensive circular system in lined grow-out ponds with minimal water replacement. Five intensive density levels (100, 300, 500, 700 and 900 org m-3) were considered. The water quality parameters measured for the 98 days grow-out period was within the permissible range for P. vannamei. TAN, nitrate and total phosphorus water quality parameters were significantly higher (P < 0,05) at the higher density. Growth rates and survival decrease as density increases after 300 org m-3. Based on the results of the study, it was found that shrimp grows adequately in high biomass density (99,21 kg tank-1) and density of 500 org m-3 in an intensive photo-heterotrophic system with a maximum harvest weight of 10 g.
