Three shrimp growout trials were conducted in a 337-m 2 round pond. Juvenile Penaeus vannamei were stocked at 45 shrimp/m 2 and the trials lasted 74–85 days. Shrimp were fed once a day in trial 1 and four times per day in trials 2 and 3. In trial 1, survival was 90% and feed conversion was 2.0, while in trials 2 and 3 survival averaged 83±2.5% and feed conversion averaged 2.5±0.2. Shrimp growth dramatically increased from 0.7 g/week in trial 1 to 1.8±0.15 g/week in trials 2 and 3. Total production increased from 3360 kg/ha in trial 1 to 7406±206 kg/ha in trials 2 and 3. The combined production of trials 2 and 3 was 14 812 kg/ha in 156 days (from stocking of trial 2 to harvest of trial 3). Sedimentation rates in the pond center were 81% greater than at mid-radius and 172% greater than at the pond perimeter, indicating that the round pond design effectively concentrated sediments to the center where they were flushed out the drain. These results indicate that P. vannamei is well suited to intensive culture, exhibiting rapid growth, high survival, and uniform growth when stocked at 45 shrimp/m 2. The round pond design appears to provide a high level of control over factors critical to intensive shrimp culture.
