Parasitic isopods of fishes usually show wide distribution and low host specificity. This study investigated the occurrence of gill parasites in 120 specimens of spotted goatfish Pseudupeneus maculatus, marine fish of great economic importance for fishery community. The fish were captured monthly in the Coast of Pernambuco State, Northeast Brazil, between October 2012 and September 2013. Eleven isopods were found and identified as Rocinela signata. We observed lower infections in the gills of P. maculatus (prevalence 8.3%, mean intensity 1.6±0.3 and mean abundance 0.1±0.3) when compared to other studies of different host fishes from geographically close locations. This parasite has been reported from a wide variety of fish species, not only in Brazil, but also in the eastern Atlantic and the Pacific oceans. This is the first report of R. signata in spotted goatfish.
寄生在鱼类身上的等足类动物通常分布广泛且宿主特异性较低。本研究调查了120尾黄斑绯鲤（Pseudupeneus maculatus）样本鳃部寄生虫的发生情况，黄斑绯鲤是对渔业社区具有重要经济意义的海洋鱼类。这些鱼于2012年10月至2013年9月期间每月在巴西东北部伯南布哥州海岸捕获。共发现11只等足类动物，并鉴定为罗氏岩蟹（Rocinela signata）。与来自地理上相近地区的不同宿主鱼类的其他研究相比，我们观察到黄斑绯鲤鳃部的感染率较低（患病率8.3%，平均感染强度1.6±0.3，平均丰度0.1±0.3）。这种寄生虫不仅在巴西，而且在东大西洋和太平洋的多种鱼类中都有报道。这是罗氏岩蟹在黄斑绯鲤中的首次报道。
