Summary of the number of fish sampled by month, year, site, genetic stock of origin and hatchery (H) or wild (W) origin.

Each site was coded by the sampling design, with the first letter representing the reach and the second letter representing the habitat type (e.g., the mainstem channel of reach C was CM).

所有调查点位均依照采样设计规则进行编码，其中首字母代表河段（reach），次字母代表生境类型（habitat type）。例如，C河段的主河道编码为CM。
