中文摘要:
      对2009~2010年采自澜沧江下游的188尾中华鲱鲇(Clupisoma sinensis)进行了年龄与生长的研究。采用耳石、脊椎骨、鳃盖骨、胸鳍棘4种材料对全部样本进行年龄鉴定,耳石年龄鉴定最为准确,4~5月是年轮形成高峰期。渔获种群由1~6龄共6个龄组组成,以1~4龄个体为主。体长与耳石半径呈线性函数关系。体长与体重呈幂函数关系且幂指数接近3,属于匀速生长类型。采用Von Bertalanfy生长方程描述中华鲱鲇的生长特性。中华鲱鲇肥满度随年龄增长逐步升高,在3龄形成高峰。综合中华鲱鲇性成熟系数的变化状况分析中华鲱鲇繁殖期应处于4~8月期间。
英文摘要:
      A total of 188 specimens of Clupisoma sinensis were collected from down-stream area of Lancang River during the period from 2009 to 2010. The age discrimination and growth characteristics of C.sinensis were studied by four determination materials, otoliths, pectoral-fins, vertebra and opercula, the otoliths is the best one in age determination.The age structure of C.sinensis is aged into 6 age groups and fishes with age 1 to 4 year olds form the major proportion of the 188 specimens.New annual ring is formed before May each year.The body length and otolith radius show a relation of liner function.The relationship between body length and weight of the C.sinensis is also expressed by power function where the exponent was close to 3. Growth of C.sinensis is with constant speed style which was described with Von Bertalanffy equation.Fullness of C.sinensis increases gradually with age and reaches peak in 3 years old.The reproductive season of C.sinensis was April to August.
