光唇鱼的形态特征和血液生化指标

运用传统的形态测量方法结合分类特征研究了采自浙江省新昌县的光唇鱼样本。结果显示:背鳍为3,8;胸鳍为1,14-16;腹鳍为1,8;臀鳍为3,5;体长/体高、体长/头长、体长/吻长、体长/眼径、头长/吻长、眼径/头长数值分别为3.18±0.47、4.22±0.42、13.02±4.55、20.56±3.00、3.08±1.03、0.21±0.03。其体侧有纵条;唇后沟的间隔距离较宽,大于口宽的1/3;并对其血液生理生化等指标进行了测定,结果表明光唇鱼血液中红细胞、白细胞和中性粒细胞的平均数目分别为1.20×107个/mm3、1.74×104个/mm3、4.50×102个/mm3;检测的13项血清生化指标中除尿素氮、磷、肌酐和谷草转氨酶等几项指标外其余指标均不存在显著差异;总蛋白为44.00 g/L,葡萄糖为15.87 mmol/L,总胆固醇为7.32 mmol/L,甘油三酯为6.61mmol/L,钙为2.37mmol/L,镁为1.12mmol/L,铁为6.00mmol/L,尿酸为15.00μmol/L,谷丙转氨酶为180.00 U/L;其中血清铁的含量要明显高于钙、磷、镁,谷草转氨酶的活性要高于谷丙转氨酶;与一些不同食性淡水鱼类相比,光唇鱼血液中甘油三酯、总蛋白、血糖和钙、镁离子含量较高;结果可作为光唇鱼的正常生理常数参考值。

Study on Morphology .and Blood Biochemical Indexes of Acrossocheilus fasciatus

The Acrossocheilus fasciatus samples were investigated,using the traditional measurement methods and the classification of morphological features,the samples collected from Xinchang county,Zhejiang.The results suggested that: the number of dorsal fin was 3,8,pectoral fin 1,14-16,pelvic fin 1,8,and anal fin 3,5.The values of body length/body height,body length/head length,body length/snout length,body length/eye diameter,head length/snout length,eye diameter/head length were 3.18 ±0.47,4.22±0.42,13.02± 4.55,20.56±3.00,3.08±1.03,0.21±0.03 respectively.Taeniaes could be found on the side of the body.The distance between lip sucue was relatively wide,which is 1/3 times larger than the mouth width.The features of physiological and biochemical characters were also tested.The results suggested that the mean values of lip fish blood red cells,white blood cells and neutrophils were 1.20 ×107/mm3,1.74 ×104/mm3,4.50 ×102/mm3 respectively.In additio n,13 serum biochemical markers were investigated,significant differences were not observed,except for urea nitrogen,phosphorus,creatinine,and aspartate transaminase.The total protein of A.fasciatus was 44.00 g/L,glucose 15.87 mmol/L,cholesterol 7.32 mmol/L,triglycerides 6.61 mmol/L,calcium 2.37 mmol/L,magnesium 1.12 mmol/L,iron 6.00 mmol/L,uric acid 15.00 μmol/L,and glutami c-pyruvic transaminase 180.00 U/L.The content of iron in serum was significantly higher than that of calcium,phosphorus,magnesium.And the activity of aspartate aminotransferase was higher than that of alanine aminotransferase.When compared with the other different freshwater fishes,the content of blood triglyceride,total proteins,glucose,calcium and magnesium ion in A.fasciatus were higher.Our datas could be used as the normal physiological constant reference in the following study of A.fasciatus.
