摘要
采用淡化虾塘水添加天然盐碱水的方法，进行盐碱水环境下凡纳滨对虾（Litopenaeus vannamei）生存能力实验。探讨吉林西部盐碱水域对虾养殖技术．结果表明，未驯化幼虾在碱度为5．15～19．24mmol·L^-1的盐碱水体存活时间大于96h，在23．41～38．78mmol·L^-1的盐碱水体生存时间小于O．75h；驯化幼虾在碱度为5．15～38．78mmol·L^-1的盐碱水体存活时间大于24h．未驯化幼虾适应的盐碱水碱度上限在10mmol·L^左右。对递增碱度差的适应能力小于8mmol·L^-1．提高驯化水平，可增强幼虾对盐碱水环境的综合适应能力．碱度驯化至30mmol·L^-1的幼虾对递增碱度差和递减碱度差的适应能力分别为2～4mmlo·L^-1及3～25mmol·L^-1。可以在吉林西部碱度小于32mmol·L^-1的盐碱水域养殖凡纳滨对虾．
By supplementing natural saline-alkali water into desalinated prawn-cultivating pond, this paper studied the survival ability of Litopenaeus vannamei under saline-alkali water environment. The results showed that the survival duration of untamed juvenile shrimp was more than 96 hours at the alkalinity of saline-alkali water from 5.15 to 19.24mmol·L^-1, and less than 0.75 hours at the alkalinity from 23.41 to 38.78 mmol·L^-1. The survival duration of tamed juvenile shrimp was more than 24 hours at the alkalinity from 5.15 to 38.78mmol·L^-1. The upper limit of alkalinity adapted by untamed juvenile shrimp was about 10 mmol·L^-1, and the adaptability to the increasing disparity in alkalinity was under 8 mmol·L^-1. The adaptability of juvenile shrimp could be increased by the increase of tamed standard, and that of tamed juvenile shrimp to the alkalinity of 30mmol·L^-1 was from 2 to 4 mmol·L^-1 and from 3 to 25 mmol·L^-1 for the alkalinity disparity increase and decrease, respectively. Litopenaeus vannamei could be cultivated in the saline-alkali water with an alkalinity of 32 mmol·L^-1 in west Jilin Province.
