Despite a fishery with annual landings valued at over $50 million CAD, very little knowledge has been gathered about the ecology of the striped shrimp (Pandalus montagui Leach 1814) in the Canadian northwestern Atlantic. This information is nevertheless considered essential for developing appropriate management actions for the fishery. We used survey data collected from 2005 to 2020 in the northern Labrador Sea, Ungava Bay, and Davis Strait to examine sizes, stages of maturity, size of transition, and evidence of parasites in the striped shrimp. We also investigated potential ecological drivers affecting the presence of parasites and size of transition. We found shrimp were substantially larger than previously observed in nearby habitats. The size of transition did not remain constant throughout the time series, and instead, was a function of the average size of females and the amount of preferred habitat in the previous year. The probabilities of individuals exhibiting black gill or black shell disease, or being infected with a bopyrid parasite were generally related to sex, depth, temperature, salinity, latitude, and shrimp density. The large sizes observed in the study area and the apparent plasticity of the population to environmental changes indicate that this species should be closely monitored in the future in relation to exploitation pressure and climate change.

条纹虾的生态学和流行病学，Pandalus montagui Leach，1814 年（十足目：Caridea），位于拉布拉多海北部、戴维斯海峡和安加瓦湾，加拿大

尽管渔业年上岸量超过 5000 万加元，但关于加拿大西北部大西洋条纹虾（Pandalus montagui Leach 1814）生态学的知识却很少。然而，这些信息被认为对于制定适当的渔业管理行动至关重要。我们使用 2005 年至 2020 年在北部拉布拉多海、安加瓦湾和戴维斯海峡收集的调查数据来检查条纹虾的大小、成熟阶段、过渡大小和寄生虫的证据。我们还调查了影响寄生虫存在和过渡规模的潜在生态驱动因素。我们发现虾比以前在附近栖息地观察到的要大得多。过渡的大小在整个时间序列中并没有保持不变，相反，是前一年雌性平均大小和首选栖息地数量的函数。个体出现黑鳃病或黑壳病，或感染蛇毒寄生虫的概率通常与性别、深度、温度、盐度、纬度和虾密度有关。在研究区域观察到的大尺寸和种群对环境变化的明显可塑性表明，未来应密切监测该物种与开发压力和气候变化有关的情况。
