The bopyrid isopods are common in wild spp. but not common in aquaculture condition. This is the first study that reports the parasitizing of bopyrid isopods on the cultured . Bopyrid isopod () was identified in the branchial cavities of the fresh water prawn, from grow-out culture pond at Kuriyamangalam, India. is a new host for . A total of 1323 were checked for this study. The overall prevalence of the parasitic infestation was reached 46.2 %. The parasitic infection was higher in female (83 %) than in male (3.4 %). Highest prevalence of infestation was found in the median size group (7-8 cm) (58.7 %). Infected females were not berried unlike uninfected prawns. The parasites cause infertility and does not found any organ deformities due to the infestation. The parasite was inversely attached in the gill chamber with no lesion on the gill but the infected branchial chamber became bulged.
缩头水虱类等足目动物在野生种群中很常见，但在水产养殖环境中并不常见。这是第一项报道缩头水虱类等足目动物寄生在养殖生物上的研究。在印度库里亚芒加拉的养成养殖池塘中，从淡水虾的鳃腔中鉴定出了缩头水虱类等足目动物（具体品种未提及）。（该淡水虾品种）是（该缩头水虱类等足目动物）的新宿主。本研究共检查了1323只（淡水虾）。寄生虫感染的总体患病率达到46.2%。雌性（感染率为83%）的寄生虫感染率高于雄性（3.4%）。在中等大小组（7 - 8厘米）中发现感染率最高（58.7%）。与未感染的对虾不同，感染的雌性没有抱卵。寄生虫会导致不育，且未发现因感染而造成的任何器官畸形。寄生虫反向附着在鳃腔中，鳃上没有损伤，但受感染的鳃腔会鼓起。
