于2005年5月15日-6月4日,将体长为(1.00±0.03) cm的中国对虾Feneropenaeus chinensis仔虾暂养于池塘网箱中,暂养密度分别为150、300、450、600尾/m2,暂养20 d 后,体长分别为(2.81±0.19)、(2.57±0.22)、(2.15±0.20)、(2.01±0.32) cm,存活率分别为70.2%±2.7%、67.0%±2.8%、37.6%±3.4%、33.4%±4.1%。于2009年5月10日-29日,将体长为(0.99±0.03) cm的中国对虾仔虾暂养于池塘网箱中,暂养密度为150、300尾/m2,暂养20 d后,体长分别为(2.78±0.23)、(2.55±0.21) cm,存活率分别为70.4%±3.5%、69.5%±3.4%。于2009年6月3日-4日、2010年6月4日-5日在普兰店皮口海域(N 39毅18忆22义, E122毅23忆30义)进行小(1.0 cm)、大(2.7 cm)两种规格的中国对虾海上漂流试验,2009年试验时海况恶劣,漂流20 h后,小、大个体组的存活率分别为0、51.7%±1.5%,2010年试验时海况良好,存活率分别为88.5%±4.4%、98.5%±3.5%。以2010年黄海北部暂养1.5亿尾中国对虾为例,计算放流小、大规格的中国对虾的成本,结果表明,放流大规格中国对虾能节省24.764万元,占放流总成本的13.6%。

The postlarvae of Chinese shrimp Feneropenaeus chinensis with body length of ( 1 . 00±0 . 03 ) cm were reared in net cages disposed in a pond at a rate of 150, 300, 450 and 600 ind. /m2 for 20 days from the 15th of May to the 4 th of June in 2005 . Then the shrimp had body length of ( 2 . 81±0 . 19 ) cm and survival of 70 . 2%±2. 7% at a density of 150 ind. /m2, (2. 57±0. 22)cm and 67. 0%±2. 8% at a density of 300 ind. /m2, (2. 15±0. 20)cm and 37. 6%±3. 4% at a density of 450 ind. /m2 and (2. 01±0. 32)cm and 33. 4%±4. 1% at a density of 600 ind. /m2. The Chinese shrimp postlarvae with body length of (0. 99±0. 03)cm were reared in net cages dis-posed in a pond at a rate of 150, and 300 ind. /m2 for 20 days from 10 to 29 in May, 2009. The juveniles with body length of (2. 78±0. 23)cm and (2. 55±0. 21)cm were obtained, with survival rate of 70. 4% ±3. 5% and 69. 5% ±3. 4%. The sudden mortality of small (with body length of 1.0 cm)and large (with body length of 2. 7 cm) shrimp juveniles was studied in coastal waters of Pikou ( N39o18’22 " E122o 23 ’30") from 3 to 4 in June, 2009 and from 4 to 5 in June, 2010. The survival rate was found to be 0% in the small juveniles and 51. 7%±1. 5% in the large juveniles in the 2009 experiment due to the poor weather, and to be 88. 5%±4. 4% in the small juveniles and 98. 5%±3. 5% in the large juveniles in the 2010 experiment under the good weather. In terms of 150 million shrimp juveniles being released into the northern Yellow Sea in 2010, 247. 64 thousands yuan RMB, ac-counting for 13. 6% of the total cost, would be saved if large shrimp juveniles were released.
