蓄水季和枯水季PBDEs的浓度都以长吻鮠和黄颡鱼中最高。

The concentration of PBDEs in the long snout catfish and catfish were very high in water and dry season .

这其中就包括黄姑鱼和中华长吻鮠。

They include the spotted maigre and the Chinese long-snout catfish .

从长吻鮠越冬期间的肝体指数和条件因子变化情况看，肝体指数更多地反映了肝脏的重量变化，而条件因子则更依赖于体重的变化。

Based on the data of HSI and K , it was revealed that HSI reflected the liver weight change , and condition factor then depended on the body weight change .

生长曲线，生长速度曲线、生长加速度曲线反映出长吻鮠属均匀生长型，生长的拐点年龄为6.1龄，地外，体长、体重、吻长、全长、体国之间还进行了多元回归。

The relationship between the age and the body length and weight and growth rate and acceleration of the growth in length and in weight are given . A turning point of growth curve in weight occures at age 6.1 .

在过去的一年里，保护区经常发现如黄姑鱼等6种鱼的身影，像长吻鮠等另外6种鱼虽然没有频繁现身，但在保护区也出现过。

Six species such as the spotted maigre have been frequently found in the conservation area in the past year , and the other six species , such as the long-snout catfish are also seen in the area , though not as frequently .
