1981年春季和秋季在靠近墨西哥索诺拉州基诺的一个海湾内分别进行了两个15周的蓝对虾养成试验,每次将15000尾蓝对虾幼体(0.7～1.0克)分放在5个30平方米的浮式网箱内(3000幼体/网箱)。在春季收获时,蓝对虾个体重量、成活率和产量分别平均为5.65±0.20克、31.84±3.07%和201.8±18.3克/平方米。秋季收获时蓝对虾个体重量、成活率和产量分别平均为8.34±0.21克、45.28±3.35%和411.3±25.5克/平方米。春季的平均温度是22.3℃,秋季的平均温度是25℃。本文对开展网箱养虾工作有一定参考价值。
In the spring and autumn of 1981, two 15-week trials of blue shrimp culture were conducted in a bay near Keno, Sonora, Mexico, each containing 15,000 blue shrimp larvae (0.7-1.0 grams) in five Floating cages in 30 m2 (3000 larvae / cage). At spring harvest, individual weight, survival rate and yield of blue shrimp averaged 5.65 ± 0.20 g, 31.84 ± 3.07% and 201.8 ± 18.3 g / m 2, respectively. The average individual weight, survival rate and yield of blue shrimp in autumn harvest were 8.34 ± 0.21g, 45.28 ± 3.35% and 411.3 ± 25.5g / m2, respectively. The average temperature in spring is 22.3 ° C and in autumn the average temperature is 25 ° C. This article has a certain reference value for the development of cage shrimp farming.
