摘要/Abstract

摘要： 在水温28. 6—29. 5℃、pH8. 2条件下, 研究了管角螺Hemifusustuba稚贝[(壳高19. 5±1. 23)mm、体重(661. 4±48. 6)mg]在不同盐度下的生长和存活, 并用二点法计算出最适宜存活和生长的盐度范围。结果表明, 管角螺稚贝适宜存活盐度和最适存活盐度分别为17. 7‰—40. 8‰和25. 1‰—35. 9‰, 适宜生长盐度和最适生长盐度分别为17. 5‰—39. 9‰和27. 8‰—33. 2‰。在最适生长盐度范围内, 稚贝壳高日平均增长率为0. 358—0. 397mm·d^-¹，体重日平均增长率为44. 64—49. 09mg·d^-¹。超出上述范围, 其存活率下降、生长率降低。稚贝在盐度17. 0‰和41. 3‰的海水中适应20d后再分别移至盐度14. 0‰和45. 0‰的海水中, 72h后存活率分别为84. 0%和96. 0%, 而直接把生活在盐度为30. 5‰中的稚贝放入到盐度为14. 0‰和45. 0‰的海水, 72h后其存活率为8. 0%和0, 可见稚贝对盐度的适应能力与原生活海水盐度有关, 经过驯化后的稚贝能够扩大对盐度的适应范围, 提高对盐度的耐受力。

Abstract: Under the water temperature that ranges between 28.6 and 29.5 ℃ and pH 8.2, the growth and survival of Hemifusus tuba juveniles [shells high (19.5 ± 1.23) mm, weight (661.4±48.6) mg] at different salinity were studied. The goal is to find out the range of optimal survival salinity and optimal growth salinity to H. tuba juveniles by two-point method. The results show that the suitable survival salinity and optimal survival salinity are 17.7 ‰ - 40.8 ‰ and 25.1 ‰ - 35.9 ‰ , and that the growth suitable salinity and growth optimal salinity were 17.5 - 39.9 ‰ and 27.8 - 33.2 ‰ , respectively. In the range of growth optimal salinity, the average daily growth rate of shells and weight were 0.358 - 0.397 mm · d ^-¹and 44.64 - 49.09 mg · d ^-¹, respectively. The survival rate and the average daily growth rate of shells fell obviously when the range of salinity optimal survival salinity was exceeded. Moreover, the tolerance of salinity by H. tuba Juvenile was related to the original environmental salinity. The survival rate was 84.0% in 72h when the juveniles were adapted for 20d in the salinity of 17.0 ‰ and then t ransported to the salinity of 14.0 ‰ , and the survival rate was 96.0% when the juveniles were adapted for 20d in the salinity of then t ransported to the salinity of 45.0 ‰ . However, the survival rates were 8.0% and zero in 72h when the juveniles were t ransported from the salinity of 30.5 ‰ to 14.0 ‰ and 45.0 ‰ , respectively. Both the suitable range and the tolerance of salinity can be increased when the juvenile was domesticated in gradually changing conditions.
