The seasonal cycle of the cestode Proteocephalus sagittus (Cestoda: Proteocephalidae) was studied for the first time in the stone loach Barbatula barbatula from the Hana River, Czech Republic. A total of 180 loaches were examined monthly from January to December 2001. The parasite occurred in loaches throughout the year but infection parameters differed significantly among seasons, with the highest values of prevalence and abundance from the late winter to the early summer. Parasite recruitment took place in the winter and early spring and the worms sexually matured in the late spring and early summer. In contrast to P. torulosus, the gravid worms of which laid eggs only at the end of the spring/beginning of the summer, gravid worms of P. sagittus were also found, although in low numbers, in the autumn and early winter. The rate of infection of loach with P. sagittus was neither dependent on the sex nor on the size of its fish host.
在捷克共和国哈纳河的石斑鳅（Barbatula barbatula）中，首次对绦虫箭状原头绦虫（Proteocephalus sagittus，绦虫纲：原头绦虫科）的季节性循环进行了研究。2001年1月至12月每月共检查180条石斑鳅。该寄生虫全年都出现在石斑鳅体内，但感染参数在不同季节有显著差异，冬末至初夏的感染率和感染强度最高。寄生虫在冬季和早春开始寄生，虫体在春末和初夏性成熟。与仅在春末/夏初产卵的圆叶原头绦虫（P. torulosus）不同，箭状原头绦虫的孕节在秋季和初冬也有发现，尽管数量较少。石斑鳅被箭状原头绦虫的感染率既不取决于宿主鱼类的性别，也不取决于其大小。
