N2  - The environmental temperatures preferred or selected by postlarval black tiger shrimp Penaeus monodon (body weight 84 &#177; 25 mg and body length 2.66 &#177; 0.21 cm, mean &#177; s.d.) acclimatized to 16, 20, 24, 28, 32 or 36&#176;C, were determined in a horizontal gradient (17&#8211;37&#x02DA;C). The results indicated that the crustaceans were competent in detecting thermal discontinuities and in showing preference. The mean temperature selected by the postlarvae rose from 20.0&#x02DA;C to 25.6&#x02DA;C and the mode from 15&#x02DA;C to 27&#x02DA;C when the acclimation temperature was increased from 16&#x02DA;C to 36&#x02DA;C. The preferred temperature of the shrimp was not significantly different among the groups acclimatized at 24&#x02DA;C, 28&#x02DA;C and 32&#x02DA;C. The final preferendum of the shrimp was estimated to be 23.2&#x02DA;C, which is considerably lower than the optimal growth temperature for the species.
