不同食性鱼的血红蛋白及其测定方法的比较研究

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）。

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

The ratio of their intestine length to the body length was measured,the content of hemoglobin was measured by themethod of XK-2 hemoglobin instrument,Spectrophotometer method and colorimetry in the fish with four different feeding habits(Allogyno gentic crucian;hypophthalmichthys molitrix;Parabramis pekinensis;Ophicephalus argus cantor),and their methodswere compared.The results showed that the ratio of their intestine length to body length is the sieve fish(hypophthalmichthysmolitrix) >the herbivorous fish(parabramis pekinensis) >the miscellaneous food fish(Allogyno gentic crucian) >the carnas-sial fish(ophicephalus argus cantor).And the content of hemoglobin of the XK-2 hemoglobin instrument and that of Spectro-photometer were no different but higher than that of the colorimetry,and tne method of the XK-2 hemoglobin instrument werebetter than the other method.And the content of hemoglobin is the carnassialfish(ophicephalus argus cantor) >the miscellane-ous food fish(Allogyno gentic crucian) >the sieve fish(hypophthalmichthys molitrix) >the herbivorous fish(parabramis pe-kinensis)
