| 中文摘要: |
| 以60 尾珍珠魟（Potamotrygon motoro）为研究对象，进行人工繁育和生长试验。在2011要2013 年间成功
繁育珍珠魟500 尾，成活率达90%。同时对人工养殖条件下珍珠魟生长特性进行研究，结果表明，珍珠魟的体重（W）
与日龄（t）呈线性关系院W= 3.7641t-75.704，R2=0.9623；体盘长（L）与日龄呈线性关系院L=0.0536t+10.952，R2=0.9834；体
重与体盘长呈幂函数关系院W=0.0411L3.094，R2=0.9924，指数b 为3.094，说明人工养殖条件下珍珠魟属于等比生长类
型，体重与体盘长生长基本同步。 |
| 英文摘要: |
| During 2011 to 2013, 500 Potamotrygon motoro were successfully reproduced and the survival rate was
more than 90%. 60 juveniles were chosen to study the growth characteristics of P. motoro under artificial farming condition.
The result showed that there was a linear relationship between body weight (W) and day age (t), and the regressive equation
was W =3.7641t-75.704, R2=0.9632; there was also a linear relationship between body length (L) and day age, and the
regressive equation was L=0.0536t+10.952, R2=0.9834; there was a power function relationship between body weight and
body length, and the relationship was W =0.0411L3.094, R2=0.9924. The power was close to 3, indicating that the growth of
weight was as fast as that of the body length of P. motoro, and the growth was isometric. |
