Fisheries play a crucial role in aquatic ecosystems, a resource with ecological and economic importance. Measuring parasite prevalence is necessary to assess these fish species' health and well-being. Within the Sistan region, this study sought to estimate the prevalence and intensity of infection with plerocercoid () in seven fish species and identify factors such as fish weight, seasonality, and fishing location that might influence infection rates. 2800 fish from seven species were obtained in the Sistan region throughout four seasons. Fish samples from three weight categories (<200gr, 200-400gr, 400gr<) were examined parasitologically. was detected in 96/2800 (3.4%) of fishs. There was a variation in prevalence among fish species. (), () () and () showed no infection. () showed a prevalence of 1.5% (6/400), () 15% (60/400), and () 7.5% (30/400). It was found that infection prevalence was significantly influenced by fish weight in and . A higher prevalence was found in fish with lower weight. Infection rates significantly fluctuated with season across species, but fishing locations had no significant difference. The present study highlights the significant prevalence of infections in fish populations within Iran's Sistan region, underscoring the need for ongoing monitoring and research to inform effective fishery management strategies. Future studies should focus on long-term monitoring efforts and consider the broader global context of fish parasitology to understand parasite-host interactions better and inform conservation measures worldwide.
渔业在水生生态系统中起着至关重要的作用，是一种具有生态和经济重要性的资源。测量寄生虫感染率对于评估这些鱼类的健康状况至关重要。在锡斯坦地区，本研究旨在估计七种鱼类中裂头蚴的感染率和感染强度，并确定可能影响感染率的因素，如鱼的体重、季节和捕鱼地点。在锡斯坦地区的四个季节里，共采集了来自七个物种的2800条鱼。对三个体重类别（<200克、200 - 400克、>400克）的鱼样本进行了寄生虫学检查。在2800条鱼中有96条（3.4%）检测到了裂头蚴。不同鱼类的感染率存在差异。（某些鱼类名称未明确写出）未显示出感染。（某些鱼类名称未明确写出）的感染率为1.5%（6/400），（某些鱼类名称未明确写出）为15%（60/400），（某些鱼类名称未明确写出）为7.5%（30/400）。研究发现，在某些鱼类中，感染率受鱼体重的显著影响。体重较轻的鱼感染率更高。不同物种的感染率随季节有显著波动，但捕鱼地点没有显著差异。本研究突出了伊朗锡斯坦地区鱼类种群中裂头蚴感染的显著发生率，强调需要持续监测和研究，以为有效的渔业管理策略提供依据。未来的研究应专注于长期监测工作，并考虑鱼类寄生虫学更广泛的全球背景，以更好地理解寄生虫与宿主的相互作用，并为全球的保护措施提供信息。
