依据238尾鱼的测量数值,研究了乌苏里江野生唇(Hemibarbuslabeo)的鳞片及生长特征,并调查了乌苏里江抓吉镇江段唇的捕捞资源情况。结果表明,唇的鳞片较大,为规则圆鳞,年轮特征清晰,易于分辨,鳞径(R鳞径)与生长时间(年龄t)的回归方程为R鳞径=0.8583t+2.275(n=238,r=0.9868),体长与鳞径的回归方程为L=4.3326R鳞径+0.0293(n=238,r=0.9903)。乌苏里江唇体重与体长的回归方程为W=0.0115L3.0868(n=238,r=0.9962),其生长特征适合VonBertalanffy生长方程,体重的生长拐点t=4.59龄,W=340.90g。在乌苏里江抓吉镇江段主要捕捞唇的时间从每年开冰期4月20日到封冰期11月15日左右,其捕捞量随季节的变化而不同,4～5月、10～11月数量最多,为100～150kg/d,6～7月为50～100kg/d,8～9月较少,为30～40kg/d。
Based on the measurements of 238 fish, the scales and growth characteristics of the wild snout (Hemibarbuslabeo) in the Ussuri River were studied. The fishing resources of the snakeheads in the Jijiezhen section of the Wusuli River were investigated. The results showed that the scale of lip was larger and regular round scales, and the characteristics of rings were clear and easy to distinguish. The regression equation of scale diameter (R scale) and growth time ( age t) was R scale = 0.8583t + 2.275 n = 238, r = 0.9868). The regression equation of body length and scale diameter was L = 4.3326R and the diameter of scale was +0.0293 (n = 238, r = 0.9903). The regression equation of body weight and body length of Wusuli River was W = 0.0115L3.0868 (n = 238, r = 0.9962), and its growth characteristics were suitable for Von Bertalanffy growth equation. The body weight inflection point t = 4.59, W = 340.90g . In the Wusuli River grasping the main section of the town of Kyrgyzstan lip catfish from the annual open ice April 20 to the closure of ice around November 15, the catches vary with the seasons, April to May, from October to November The largest number is 100 ~ 150kg / d, 6 ~ July is 50 ~ 100kg / d, 8 ~ September is less, 30 ~ 40kg / d.
