青海湖裸鲤的无机元素

１９８９年５月及１０月测定青海湖主要经济鱼类青海湖裸鲤Ｇｙｍｎｏｃｙｐｒｉｓ ｐｒｚｅｗａｌｓｋｉｉ ｐｒｚｅｗａｌｓｋｉｉ（Ｋｅｓｓｌｌｅｒ）不同性别，９种组织中的人体及动物必需常量元素６种，微量元素１０种的含量。存在不同组织、性别、季节及年份的差异。雌鱼常量元素总量是骨＞鳞＞鳃＞肝＞肌肉＞肠＞心＞卵巢＞皮；微量元素总量肠＞鳞＞心＞鳃＞骨＞肝＞皮＞卵巢＜肌肉。雄鱼常量元素总量是骨＞鳞＞鳃＞皮＞精

This paper deals with the contents of mineral elements in nine tissues of Gymnocypris przewalskii przewalskii, which are scale, skin, gill, skeleton, muscle,intestine, liver, heart, sex gland.The mineral elements concentrations in total body of Gymnocypris przewalskii przewalskii (Female) are Ca(35934), P(25511), S(8700), K(5166.3), Na(4678), Mg (1314.4), Fe(180. 5), Zn(108. 7), Mn(67. 7), Sr(56. 5), Cu(14 .5), Cr(7.96), Mo(5. 93),V(3. 31 ), Ni(1 .6), Co(0. 149)mg/kg dry weight respectively. Those in male are Ca (45506. 5), P(29822. 2), S(10622), Na(7055. 5), K(5711. 3), Mg(1380. 1), Zn(173. 5),Fe(160.4), Sr(55. 3), Cu(24, 4), Cr(15. 75), Mn(4. 502). Mo(4 .02), V(3. 04), Ni(2,6),Co(0 .021) mg/kg dry weight respectively.There are sex, seasonal, years change in content of mineral elements.
