Finding a balance: Reproductive trade-offs in parasitic isopods of the family Cymothoidae
Parasitology ResearchIn this study conducted along the coast of Odisha, India, reproductive trade-offs in isopods of the family Cymothoidae were investigated, focusing on the relationship between the number vs. volume of eggs and the percentage of brood to body volume. Ovigerous females from species with substantial sample sizes (n > 30) were analyzed to understand their ...

Sex-reversal and androgenic gland in the fish parasite Irona far (cymothoidae: isopoda: crustacea)
International Journal for Parasitology, 1974Abstract The sequence of changes in the primary and secondary sexual characters of the parasitic isopod Irona far during sex-reversal indicate that it is synchronised with the degeneration of the androgenic gland. The gonad is typically hermaphroditic. During the male stage the testicular utricles are large and active but the ovarian region remains

Host Specificity and Position On the Host in Nerocila Phaeopleura Bleeker (Isopoda, Cymothoidae)
Crustaceana, 1974[Nerocila phaeopleura Bleeker ist wirtspezifisch; der Hauptwirt ist Sardinella gibbosa (Bleeker). Jedoch werden auch andere, verwandte oder morphologisch ahnliche Fische gelegentlich befallen. Der Parasit verursacht eine tiefe Wunde; dieser Umstand legt die Vermutung nahe, das der Parasit an der gleichen Stelle verbleibt, also nicht auf dem Wirtskorper

Riscontri batteriologici in isopodi Cymothoidae, parassiti di alcune specie ittiche
1996Gli Autori, al fine di contribuire alla conoscenza dei problemi igienico-sanitari legati al parassitismo dei pesci, indagano sulla presenza di vibrioni alofili e coliformi in Isopodi Cymothoidae che parassitano frequentemente la cavità orale e la cute di alcune specie ittiche.
