不同食性鱼的血红蛋白及其测定方法的比较研究

Comparative Study of the Hemoglobin Content and its measured methods inFish with different feeding habits

测定4种不同食性鱼(异育银鲫、白鲢、鳊鱼、乌鳢)的肠体比,并用XK-2型血红蛋白仪法、分光光度计法和比色法3种方法测定其血红蛋白,同时比较3种不同测定方法之间的差异。试验结果表明:肠体比大小:滤食性鱼(白鲢)>草食性鱼(鳊鱼)>杂食性鱼(异育银鲫)>肉食性鱼(乌鳢);在3种测定方法中,比色法测定的值最低且粗糙,而XK-2型血红蛋白仪法和Unico 7202B型分光光度计法测定的血红蛋白值差异不显著,但因前者方便、实用,因此以XK-2型血红蛋白仪法为佳;不同食性鱼的血红蛋白大小:肉食性鱼(乌鳢)>杂食性鱼(异育银鲫)>滤食性鱼(白鲢)>草食性鱼(鳊鱼)。

The ratio of their intestine length to the body length was measured, the content of hemoglobin was measured by the method of XK - 2 hemoglobin instrument , Spectrophotometer method and colorimetry in the fish with four different feeding habits （ Allogyno gentic crucian ; hypophthalmichthys molitrix ; Parabramis pekineusis;Ophicephalus argus cantor） ,and their methods were compared. The results showed that the ratio of their intestine length to body length is the sieve fish （ hypophthalmichthys molitrix） 〉 the herbivorous fish（ parabramis pekinensis） 〉 the miscellaneous food fish（ Allogyno gentic crucian） 〉 the carnassial fish （ophicephalus argus cantor）. And the content of hemoglobin of the XK - 2 hemoglobin instrument and that of Spectrophotometer were no different but higher than that of the colorimetry , and me method of the XK - 2 hemoglobin instrument were better than the other method. And the content of hemoglobin is the carnassialfish（ophicephalus argus cantor） 〉 the miscellaneous food fish （Allogyno gentic crucian） 〉 the sieve fish （hypophthalmichthys molltrix） 〉 the herbivorous fish（parabramis pekinensis）
