摘要
1999—2001 年 3 a 的高产试验结果显示，在符合一定条件的虾塘中和恰当的管理下，在广西沿海进行凡纳对虾（Penaeus vannamei Boone）的集约化养殖是可行的。在平均放苗密度约 74 尾／m2 时，凡纳对虾的平均单位产量可达到 7 224.35 kg／hm2。在一定的放苗密度范围（27～81 尾／m2）和养殖期限(99～139 d) 内，对虾单产与放苗密度和养殖天数正相关。蛋白质水平为 35 % 的配合饲料可以满足集约化养殖的凡纳对虾的需要。
The results of farming trials of Penaeus vannamei Boone indicate that under proper management Penaeus vannamei Boone could be cultured intensively in well-equipped shrimp ponds at Guangxi coast. The average output of the shrimp can reach 7 224.35 kg/hm2 at the stocking density of 74 pl/m2. The final biomass of the shrimp is positively correlated to the initial stocking density of postlarvae and duration of farming when the stocking density ranges from 27 to 81 pl/m2, and duration from 99 days to 139 days. The formulated feed having protein level of 35 % can meet the demand of intensively cultured Penaeus vannamei Boone.
