| 摘 要： | 对采自重庆长江江津江段的太湖新银鱼(Neosalanx taihuensis)耳石日轮与生长进行了研究。太湖新银鱼矢耳石形状近圆形,体长(Y)与耳石长半径(X)之间呈线性相关,其关系式为Y=0.1099X+16.986,R2=0.7626。耳石日轮环纹清晰,以中心核为起点圆形规则排列,其上具有明显的过渡轮纹。太湖新银鱼体长(Y)与日轮(X)呈线性关系,其关系式为Y=0.2631X+23.924,R2=0.8057;体重(Y)与日轮(X)呈指数关系,其关系式为Y=0.0446e0.0244X,R2=0.8104。太湖新银鱼体重(Y)与体长(X)间呈显著的幂函数关系Y=0.000001X3.3529,R2=0.9163。 |

| Abstract: | Daily-age increment of otolith and growth of Taihu icefish,Neosalanx taihuensis from Yangtze River in Jiangjin of Chongqing city were studied in this paper.The otolith was nearly round,and the relationship between long radius Y and body length X was Y=0.1099X 16.986,R2=0.7626.Veins in the otolith were clear,arrayed orderly,and had transition veins.The relationship between body length Y and daily-age X was Y=0.2631X 23.924,R2=0.8057;and the relationship between body weight Y and daily-age X was Y=0.0446e0.0244X,R2=0.8104.The body weight Y was related to body length X,the equation was Y=0.000001X3.3529,R2=0.9163. |
