Abstract
Based on an extensive literature search, the present overview discusses the economic relevant diseases of Siluroidei, cultured for human consumption. One herpes virus and two irido viruses play a significant role for channel catfish (Ictalurus punctatus), sheatfish (Silurus glanis ) and yellow bullhead (1. melas )culture, respectively. There is only one fish species-specific bacterial disease which has an economic impact in the catfish industry: Edwardsiella ictaluri. Secondary infections with opportunistic bacteria and fungi are of interest in all catfish species cultured both under intensive and extensive circumstances. Etiology, pathology, prevention and treatment are shortly discussed for all diseases. Also some diseases of unknown etiology, which occur in African (Clarias gariepinus ) and Asian (C. batrachus ) catfish, are described.


Résumé
Cette synthèse, établie d'après une importante recherche bibliographique, fait le point sur les maladies des Siluroidei, cultivés pour la consommation humaine, ayant des conséquences économiques notables. Un virus de l'herpès et deux irido-virus jouent un rôle significatif dans les élevages de poisson-chat américain (Ictalurus punctatus), de poisson-chat européen (Silurus glanis) et d'Ictalurus melas. Il n'y a qu'une maladie bactérienne spécifique qui a un impact économique dans l'industrie du poisson-chat: Edwarsiella ictaluri. Des infections secondaires dues à des bactéries et des champignons sont présentes chez toutes les espèces cultivées en élevage de type intensif ou non. L'étiologie, la pathologie, la prévention et le traitement sont brièvement discutés pour chacune des maladies. Quelques maladies dont l'étiologie est inconnue, observées chez le poisson-chat africain (Clarias gariepinus) et chez le poisson-chat asiatique (C. batrachus) sont également décrites.

What is OpenURL?

The OpenURL standard is a protocol for transmission of metadata describing the resource that you wish to access. An OpenURL link contains article metadata and directs it to the OpenURL server of your choice. The OpenURL server can provide access to the resource and also offer complementary services (specific search engine, export of references...). The OpenURL link can be generated by different means.
  • If your librarian has set up your subscription with an OpenURL resolver, OpenURL links appear automatically on the abstract pages.
  • You can define your own OpenURL resolver with your EDPS Account. In this case your choice will be given priority over that of your library.
  • You can use an add-on for your browser (Firefox or I.E.) to display OpenURL links on a page (see http://www.openly.com/openurlref/). You should disable this module if you wish to use the OpenURL server that you or your library have defined.
