Basic reproductive biology of daggertooth pike conger, Muraenesox cinereus: A possible model for oogenesis in Anguilliformes.

Introduction: Eels are animals commonly used in zoological research, as these species have a unique catadromous life history and belong to a phylogenetically ancient group of Teleostei. However, eel reproduction is difficult to investigate, since mature samples are not easily obtainable in the wild. In this study, we tested daggertooth pike conger (Muraenesox cinereus), an Anguilliformes species, as a potential model for the investigation of the reproductive biology of eels.

Base changes in the fliC gene of Edwardsiella tarda: possible effects on flagellation and motility.

Edwardsiella tarda is a broad host-range pathogen infecting both animals and humans. E. tarda isolates from red sea bream Pagrus major are non-motile, whereas isolates from Japanese eel Anguilla japonica and Japanese flounder Paralichthys olivaceus are motile with peritrichous flagella.
