The effects of the fish parasitic isopod, Ceratothoa oestroides (Risso), on haematological parameters of its cage-cultured sea bass host, Dicentrarchus labrax (L.), were studied. Analyses of blood parameters (cell counts, haemoglobin content and haematocrit) were carried out on parasitized and unparasitized sea bass from a fish farm in Turkey. Parasitized fish had significantly lowered erythrocyte counts, haematocrit and haemoglobin values and significantly increased leucocyte counts. Blood feeding by C. oestroides thus produces a post-haemorrhagic anaemia and the fish appear to mount an immune response to the presence of parasites.
研究了鱼类寄生等足类动物——牡蛎似角鱼虱（Ceratothoa oestroides，里索）对其网箱养殖的鲈鱼宿主——欧洲鲈鱼（Dicentrarchus labrax，林奈）血液学参数的影响。对来自土耳其一个养鱼场的寄生和未寄生鲈鱼进行了血液参数分析（细胞计数、血红蛋白含量和血细胞比容）。被寄生的鱼红细胞计数、血细胞比容和血红蛋白值显著降低，白细胞计数显著增加。因此，牡蛎似角鱼虱吸血会导致出血后贫血，并且鱼似乎对寄生虫的存在产生了免疫反应。
