嘉陵江大鳍鳠和瓦氏黄颡鱼血液学指标的研究

研究了大鳍鳠和瓦氏黄颡鱼血液学指标的季节变化及种间差异，旨在为探讨三峡工程所引起的环境变化，对两种鱼所产生的生理生态学影响提供基础资料。于2002年9月至2003年6月期间，分春、夏、秋和冬4个季节在嘉陵江水土镇以下江段共采集大鳍鳠111尾，瓦氏黄颡鱼124尾。测定了这两种鱼的红细胞数量、血红蛋白含量、平均红细胞血红蛋白含量、血清葡萄糖浓度、血清甘油三酯浓度和血清总蛋白浓度等6项血液学指标。结果表明，两种鱼的多项血液学指标均存在显著的季节间差异，血液指标的变化趋势并不是随水温的升高而升高。繁殖期两种鱼的血清甘油三酯浓度均显著降低。两种鱼的血清葡萄糖和甘油三酯浓度存在种间差异，瓦氏黄颡鱼的血清葡萄糖和甘油三酯浓度均显著高于大鳍鳠。

THE STUDY ON HAEMATOLOGICAL PARAMETERS OF MYSTUS MACROPTERUS AND PELTEOBAGRUS VACHELLII IN JIALING RIVER

In order to document the data as a baseline for future study on environmental impact of the Three Gorges Project on the fishes,seasonal variation in haematological parameters of Mystus macropterus and Pelteobagrus vachelli were investigated as well as the difference between the two species in this study. From September,2002 to June, 2003, 111 Mystus macropterus and 124 Pelteobagrus vachelli were collected in Spring, Summer, Autumn and Winter in the Jialing River between Shuitu Town and Ciqikou. Red blood cells, haemoglobin contents, mean cellular haemoglobin contents, serum glucose concentrations,serum triglyceride concentrations, and serum total protein concentrations in the two species were measured. The results indicated that there were significant differences in each haematological parameter among seasons in either of the two species and these haematological parameters did not increase with water temperature. Serum triglyceride concentration in either of the two species decreased significantly in spawning season, Both serum glucose concentration and serum triglyceride concentration was significantly different between the two species. Serum glucose concentration and serum triglyceride concentration in Pelteobagrus vachelli were significantly higher than those in Mystus macropterus in each season.
