| 中文摘要: |
| 2009年对塔里木河干流叶尔羌高原鳅[Triyplophysa(Hedinichthys)yarkandensis(Day)]群体生物学进行研究。叶尔羌高原鳅体长、体重相关方程为:W=0.0190L2.8911;相对怀卵量平均为(1160.7±364.7)粒/g,性腺处于Ⅳ期发育阶段的雌、雄鱼平均成熟系数分别为(13.59±5.21)%、(0.79±0.26)%;集中产卵时间在6-7月份,繁殖水温约为22℃。食物组成以水生高等植物(秋季)和水生昆虫(春季)为主,秋季的摄食率、饱满度及摄食强度等指标远高于春季。春季群体,体长5~8cm、体重4.1~8.1g,主要为繁殖群体;秋季群体,体长2~5cm、体重0.1~4.1g,主要为育肥生长阶段的幼小群体。当干流全线有一定流量或有洪水暴发时,叶尔羌高原鳅遍布于塔里木河干流全线,并在干流鱼类种群数量中占优势地位,其种群资源主要集中在塔里木河干流阿拉尔河段;该鱼属于广温性(0.2~33℃)底层小型鱼,具有耐低氧、喜集群及短距洄游特性。 |

| The biological characters of Triyplophysa (Hedinichthys)Yarkandensis (Day) population from the mainstream of Tarim River were study in 2009. The length-weight relationship equations was W=0. 0190L2.8911. The results showed that the average relative fecundity was(1 160. 7±364. 7)eggs/g and the maturate coefficient of female and male fishes with Ⅳ gonad was(13.59±5.21)% and(0.79±0.26)%，respectively. Main spawning occurred in June and July and the water temperature of breeding was about 22℃ .The aquatic higher plant and aquatic insects were the main food in autumn and spring，respectively，and the ingestion rate，fullness index and feeding intensity were higher in autumn than that of spring. The population composition of body length and bodyweight in spring were 5-8 cm and 4. 1-8. 1g，respectively，and this population was main breeding population.While population composition of body length and body weight in autumn were 2- 5cm and 0. 1-4. 1g，respective1y，and the fishes in this stage were juvenal population during growth period. T.(Hedinichthys) yarkandensis was found everywhere in the main stream of Tarim River when having certain flow in the main stream or happening flooding，and it would be advantage specie in the fish species population of main stream. The resources of T.(Hedinichthys)yarkandensis concentrated in Alar River of he main stream of Tarim River. T.(Hedinichthys ) yarkandensis belong to small eurythermic bottom fish and it had the characters of bearing hypoxia，liking assembly and short distance migration.
