摘    要:在盐度20、温度28.0±0.2℃条件下,采用密封流水方法进行了拟穴青蟹幼蟹耗氧率和窒息点的研究。结果表明:拟穴青蟹Ⅴ期幼蟹的平均耗氧率高于Ⅵ期幼蟹,Ⅴ期幼蟹的窒息点也高于Ⅵ期幼蟹。其中,当蟹苗体质量为1.00±0.22 g时,耗氧率为0.437 2±0.083 mg/(g.h),耗氧量0.423 7±0.080 mg/(ind.h),窒息点为0.716 0±0.017 mg/L;当蟹苗体质量为1.81±0.30 g时,耗氧率为0.381 6±0.081 mg/(g.h),耗氧量0.671 7±0.140 mg/(ind.h),窒息点为0.698 7±0.011 mg/L。实验发现,拟穴青蟹幼蟹的耗氧率和耗氧量具有比较明显的昼夜变化规律,其峰值出现在20∶00及02∶00左右,谷值出现在08∶00及16∶00。研究结果可为拟穴青蟹养殖生产中制定合理的苗种放养密度和养殖工艺提供参考依据。

关 键 词:拟穴青蟹  幼蟹  耗氧率  窒息点

Abstract:At salinity 20 and temperature 28±0.2 ℃,the oxygen consumption rate and suffocation point of juvenile crab Scylla paramamosian were studied by sealed continuous-flow method.Results showed that the average oxygen consumption rate and suffocation point of phase V juvenile S.paramamosian are higher than that of phaseVI juveniles.The juvenile crab with body weight of 1.00±0.22 g had the oxygen consumption rate of 0.437 2±0.083 mg/(g·h),the oxygen consumption of 0.423 7±0.080 mg/(ind·h) and the suffocation point of 0.716 0±0.017 mg/L;the juvenile crab with body weight of 1.81±0.30 g had the oxygen consumption rate of 0.381 6±0.081 mg/(g·h),the oxygen consumption of 0.671 7±0.140 mg/(ind·h) and the suffocation point of 0.698 7±0.011 mg/L.It was found that the oxygen consumption rate and oxygen consumption of juvenile S.paramamosian had obvious diurnal variation.The maximum value appeared at about 20∶00 and 02∶00 and the minimum value appeared at 08∶00 and 16∶00.The study can provide valuable reference for making up optimal fry stocking density and crab aquaculture techniques.
Keywords:Scylla paramamosian  juvenile  oxygen consumption rate  suffocation point
