Two species of parasitic copepods (Siphonostomatoida: Caligidae), Caligus sclerotinosus Roubal, Armitage & Rohde, 1983, parasitic on red seabream Pagrus major (Temminck & Schlegel), and Lepeophtheirus longiventralis Yü & Wu, 1932, parasitic on spotted halibut Verasper variegatus (Temminck & Schlegel), are redescribed based on material found on their respective hosts cultured in Japan. Both species are new to Japan. Preliminary observation on the occurrence of L. longiventralis indicates that the larval development takes place on the body surface of the host and only the post-mated female migrates into the host's gill-cavities. Whilst the occurrence of L. longiventralis in Japan can be considered as due to natural causes, the occurrence of C. sclerotinosus is likely due to anthropogenic activities.
基于在日本养殖的宿主身上发现的材料，对两种寄生桡足类动物（管颚目：鱼虱科）进行了重新描述，它们分别是1983年发现的寄生于真鲷（Pagrus major，由Temminck和Schlegel命名）的硬鳞鱼虱（Caligus sclerotinosus Roubal、Armitage和Rohde），以及1932年发现的寄生于星斑川鲽（Verasper variegatus，由Temminck和Schlegel命名）的长腹鱼虱（Lepeophtheirus longiventralis Yü和Wu）。这两个物种在日本均为首次发现。对长腹鱼虱发生情况的初步观察表明，其幼体发育在宿主身体表面进行，只有交配后的雌体迁移到宿主的鳃腔中。虽然长腹鱼虱在日本的出现可被认为是自然原因所致，但硬鳞鱼虱的出现可能是人为活动造成的。
