摘要
用特殊VBGE生长模型对黄花泡乌鳢 (O argus)的生长进行拟合。结果表明 :特殊的VBGE生长模型能较好地反映黄花泡乌鳢的生长过程及其变化规律。根据r -选择和k -选择理论 ,通过主要生态学参数的分析可知 :黄花泡乌鳢的生活史类型偏向r -选择型。
The results showed that the relationship between body length or body weight and age can be better described by the von bertalanff growth equation (VBGE) According to the typical characteristics of r and k selection and the given values of seven ecological parameters, it is concluded that the life history pattern of Snakehead fish (O argus) tends to r selection
