The First Data about Otolith Dimensions-Fish Length Relationships of Wels catfish, (Silurus glanis L., 1758)

Sperm Cryopreservation of Two European Predator Fish Species, the Pikeperch (Sander lucioperca) and the Wels Catfish (Silurus glanis)

Growth of Wels (silurus Glanis L.) in the Vistula River and the Zegrzyñski Reservoir

The age of wels (Silurus glanis L.) and the back calculated length at subsequent ages were estimated using sections of the first pectoral fins. The growth of this species in the Vistula River follows the von Bertallanfy curve. Some fish grew faster in the Zegrzyñski Reservoir after its inundation in 1962 than they had before. The two populations exhibited an intermediate growth rate which was b...

The occurrence of helminth parasites in the gastrointestinal of catfish (Silurus glanis Linnaeus 1758) from the Zarrine-roud river, Iran

This investigation was undertaken to verify the prevalence of helminths parasites in the gastrointestinal tract of catfish. A total number of 116 catfish (Silurus glanis) were collected from Zarrine-roud river and examined for helminths. Fish were examined after washing contents of gastrointestinal tract and observed for the presence of helminths using a stereo microscope and a light microscope...
