摘要
取实验鱼的脊椎骨为主要研究材料,配合胸鳍棘脱钙切片对照,得出嘉陵江瓦氏黄颡鱼的体长与体重呈幂函数正相关增长;体长与年龄呈“∫”型增长,体重与年龄生长曲线为抛物线增长。
Taking the vertebrae of experimental fish as main studying material,and the decalcified sections of thoracic fin spine as control,the results showed:the body length and weight of Pelteobagrus Vachelli Richardson in Jialing River increased by the positive correlation of power function;and the body length and age increased by “ ∫” form of integrate;while the growth curve of the body weight and age increased as parabolic curre.
