为优化双齿围沙蚕养殖条件,促进沙蚕资源的合理开发和利用,作者探讨了不同盐度下(8、16、24、32、40、45)双齿围沙蚕(Perinereis aibuhitensis)耗氧率和排氨率的情况。结果表明：盐度对双齿围沙蚕的耗氧率和排氨率均有显著性影响(P<0.05)。在盐度为8~32时,耗氧率随着盐度的升高呈先下降后上升的趋势；在盐度为24时耗氧率最低(0.22 mg /(g·h)±0.01 mg/(g·h))；在盐度为32时耗氧率达到最大值(0.37 mg/(g·h)±0.05 mg/(g·h))。在盐度为8~40条件下,沙蚕的排氨率随着盐度的升高呈先降低后上升的趋势；在盐度为24时,双齿围沙蚕的排氨率最低(0.10μmol/(g·h)±0.02μmol/(g·h))；当盐度为40时排氨率达到最大值(0.94μmol/(g·h)±0.11μmol/(g·h))。盐度为8~40时,沙蚕的O︰N比值随着盐度的上升呈先升高后降低的趋势,在盐度24和32时,沙蚕的 O︰N 比值分别为130.84和126.47,且变化较小,当盐度40时, O︰N比值急剧下降到13.3,然后再度上升。综合上述结果,双齿围沙蚕生活的最适盐度为24~32。
為優化雙齒圍沙蠶養殖條件,促進沙蠶資源的閤理開髮和利用,作者探討瞭不同鹽度下(8、16、24、32、40、45)雙齒圍沙蠶(Perinereis aibuhitensis)耗氧率和排氨率的情況。結果錶明：鹽度對雙齒圍沙蠶的耗氧率和排氨率均有顯著性影響(P<0.05)。在鹽度為8~32時,耗氧率隨著鹽度的升高呈先下降後上升的趨勢；在鹽度為24時耗氧率最低(0.22 mg /(g·h)±0.01 mg/(g·h))；在鹽度為32時耗氧率達到最大值(0.37 mg/(g·h)±0.05 mg/(g·h))。在鹽度為8~40條件下,沙蠶的排氨率隨著鹽度的升高呈先降低後上升的趨勢；在鹽度為24時,雙齒圍沙蠶的排氨率最低(0.10μmol/(g·h)±0.02μmol/(g·h))；噹鹽度為40時排氨率達到最大值(0.94μmol/(g·h)±0.11μmol/(g·h))。鹽度為8~40時,沙蠶的O︰N比值隨著鹽度的上升呈先升高後降低的趨勢,在鹽度24和32時,沙蠶的 O︰N 比值分彆為130.84和126.47,且變化較小,噹鹽度40時, O︰N比值急劇下降到13.3,然後再度上升。綜閤上述結果,雙齒圍沙蠶生活的最適鹽度為24~32。

The oxygen consumption rate and ammonia-N excretion rate of Perinereis aibuhitensis were determined at different salinity (8, 16, 24, 32, 40 and 45) in order to optimize P. aibuhitensis farming conditions and promote the rational development and utilization of Nereis resources. The results showed that (1) The oxygen consumption rate and ammonia-N excretion rate were significantly affected by salinity (P<0.05); (2) oxygen consumption rate first decreased and then increased with the increase of salinity at the range of 8 to 32, which was the lowest (0.22±0.01 mg /g·h) at the salinity of 24, and reached the maximum value (0.37±0.05 mg /(g·h)) at 32; (3) ammonia-N excretion rate first decreased and then increased with the increase of salinity at the range of 8 to 40. At salinity of 24, ammonia-N excretion rate was the lowest, and reached the maximum value at the salinity of 40;(4) O︰N ratio increased at the salinity range of 8 to 40, and showed little fluctuation. At the range of 24 and 32, O︰N ratios were 130.84 and 126.47, respectively, which were pretty high, and the ratio sharply declined to 13.30 at the salinity of 40, and then it increased again. The results suggest that the optimal salinity of P. aibuhitensis would be at the range of 24 to 32.
