Influence on the distribution of infected snail by the excrement of fisherman in the downstream of Qiupu River

目的观察秋浦河下游渔船民粪便污染对感染性钉镙分布的影响。方法通过对秋浦河下游渔船民停靠情况及秋浦河外滩螺情进行调查,分析感染性钉镙分布与渔船民分布的关系。结果有渔船停靠的7个流行村河滩中,4个流行村滩地有感染性钉螺分布;无渔船停靠的7个流行村河滩均未发现感染性钉螺。结论渔船民粪便污染对秋浦河下游外滩感染性钉镙分布的具有重要作用。

Objective To observe the influence on the distribution of infected snail by the excrement of fisherman in the downstream of Qiupu River. Methods To survey the anchor spots of fishing boats and the snail situation along the downstream of Qiupu River , and analyze the relationship between the distribution of infected snail and the dwelling of fisherman. Results Among the seven villages which had fishing boat anchor, there were four villages which were found infected snail on the river beach.
