摘要

The weak in survival rates and low productivity of spiny lobster are influenced by stock density. Thus it is necessary to find the optimum stock density to minimize stress levels and increase productivity. This study was consisted of 2 treatments, consisting of a 25 individuals/m2 and 50 individuals/m2 with a sheltered environment. The research analysis used descriptive analysis. The lowest stress levels was found in treatment of 25 lobsters/m2 (cortisol 1.17±0.14 nmol/L and glucose level 8.34±0.5 mg/dL) and the highest weight gain (26.29±1.69%) as well as the specific growth rate (0.77±0.014%). However, the highest value of survival rate of spiny lobsters (95±0.03%) with lowest specific growth and weight gain was found in 50 lobsters/m2 treatments.
