南海鸢乌贼耳石微量元素研究

Trace elements in the statoliths of Sthenoteuthis oualaniensis in the South China Sea

    摘要
  • 摘要: 根据2012年9月～10月于南海采集的鸢乌贼(Sthenoteuthis oualaniensis)样本,利用激光剥蚀电感等离子质谱法(laser ablation inductively coupled plasma mass spectrometry, LA-ICP-MS)分析鸢乌贼耳石微量元素组成及分布。结果显示,南海鸢乌贼耳石含量前10位的元素依次为钙(Ca)、锶(Sr)、钠(Na)、磷(P)、钾(K)、镁(Mg)、锌(Zn)、铝(Al)、铜(Cu)和镍(Ni)。P方差分析发现,鸢乌贼耳石微量元素Ca(P=0.017)、Sr(P=0.016)、Na(P=0.042) 种群差异显著(P0.05) ; 中型群Ca(P=0.026)、Sr(P=0.021)、Na(P=0.025)性别差异显著(P0.05) , 微型群性别差异不显著(P0.05); 中型群Cu(P=0.002)、Ni(P=0.001)日龄差异显著(P0.05),微型群P(P=0.000)、Mg(P=0.002)、Zn(P=0.023)、Al(P=0.000)、Cu(P=0.003)日龄差异显著(P0.05)。南海鸢乌贼Sr含量随纬度的降低而减少,且 0日龄高于10日龄。

     

    Abstract: The trace elements of Sthenoteuthis oualaniensis collected from the South China Sea during September to October,2012 were analyzed by laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS). The top 10 abundant elements are calcium ( Ca),strontium (Sr), sodium (Na), phosphorus (P), potassium (K), magnesium (Mg), zinc (Zn), aluminum (Al), copper (Cu) and nickel (Ni). The analysis of variance ( ANOVA) reveals significant difference in Ca (P=0.017), Sr (P=0.016) and Na (P=0.042) between middle-form (M-form) and dwarf-form (D-form) of S.oualaniensis (P0.05); significant difference of M-form existed in Ca (P=0.026), Sr (P=0.021) and Na(P=0.042) in sex (P0.05), but no significant difference of Dformexi sted in sex (P0.05); significant difference of M-form existed in Cu (P=0.002), Ni (P=0.001) at different ages (P0.05) , and significant difference of D-form existed in P (P=0.000), Mg (P=0.002), Zn (P=0.023),Al (P=0.000) and Cu (P=0.003) at different ages (P0.05). Sr in statolith declined as latitude decreased, and the concentration of 0 dah was higher than that of 10 dah.
