通过与SELECT模型比较，认为模型使用选择性方程并区分渔获能力和捕捞努力量使得模型更具普遍性。

Compared with select model, this model was found to be more general than the select model because of the usage of selection equation and the separation of fishing power and catch effort.

基于扩展残存资源量法，提出一种根据分年龄组渔获量以及资源量指数(单位捕捞努力量渔获量，CPUE)求算鱼类的自然死亡系数(M)的新方法。

A new method for estimating fish natural mortality coefficient (m), based on the extended survivors method, using a catch-at-age data and an abundant index (catch per unit effort, CPUE) was proposed.
