The use of shelter in recirculation system aims to minimize contact between lobster. This study analyzed and determined the shelter’s ratio in the intensive nursery which can minimize the stress response and provide good seed production. This  study used completely randomized design with 4 treatments and two replications. The treatment’s type were the ratio between shelter’s number and  the lobster’s amount  inside the tank, among others 1:6; 1:3; 1:1.2 and 1:1. This research used lobster juvenile with average bodyweight 42,86±6,22 g/lobster in stocking density 40 lobster/m² which reared in 1 m³ water tank for 30 days. The results of hemolymph test (THC total protein and cholesterol) during the study showed that all of lobsters experienced stress and it wasn’t significantly different  (p>0,05) between all treatment. Water quality conditions throughout the study was still in accordance with the lobster culture standards. The growth was increased but also not significantly different (p>0.05) between treatments. The survival rate ranged from 29.55 ± 4.57 to 44.32 ± 3.35%. The high initial weight of the lobster  and the lack of playground extents outside the shelters are supposed to influence the high stress experienced by the lobster.
