Post-haemorrhagic anaemia in sea bass Dicentrarchus labrax caused by blood feeding of Ceratothoa oestroides (Isopoda: Cymothoidae)
No full textThe 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

A molecular phylogenetic framework for the evolution of parasitic strategies in cymothoid isopods (Crustacea)
Full text linkThe parasitic isopods belonging to the family Cymothoidae attach under the scales, in the gills or on the tongue of their fish hosts, exhibiting
distinctive life-histories and morphological modifications. According to conventional views, the three parasitic types (scale-, gill-, and mouthdwellers)
correspond to three distinct lineages. In this study, we have used fragments of two mitochondrial genes (large ribosomal DNA subunit,
16S rRNA, and cytochrome oxidase I) and two species for each of the three parasitic habits to present a preliminary hypothesis on the
evolutionary history of the family. Our molecular data support the monophyly of the family but suggest that – contrary to what was previously
believed – the more specialized mouth- and gill-inhabiting species are not necessarily derived from scale-dwelling ones
