Mortalités de tilapia au Ghana
Cher Karen, Comme indiqué par Naga, ce est un vrai problème ici au Ghana et en Afrique de l'Est comme l'a confirmé par Br. Walakira. Ma question est de savoir comment nous nous attaquons pour l'instant? Jusqu'à ce que nous venons de l'atelier en Octobre, allons-nous continuer à voir nos poissons meurent? Y at-il toute solution nous pouvons nous adapter jusque-là?

Walakira. My question is How do we tackle it for now? Until we come for the workshop in October, shall we continue to see our fishes die? Is there any solution we can adapt until then?

Columnaris is at its peak virulent stage in Ghana. It became so deadly causing mortality in fingerlings from 10-80% based on location of farm. On the Volta River after Akosombo and Akuse dam the problem is not much severe except few cases with less than 10% mortality but on main Lake its up to 80%. The mortality starts from 4th day after stocking and continues till 9th day by when the damage is too high. 100% fingerlings will have sickle back and confirmed columnaris. No clue how to stop. All farms blame hatchery operators and squeezing us for replacement. I hope this workshop will help us to solve problems in Ghana. If possible please conduct some program in Ghana to enlighten farmers in Ghana.

Flavobacterium is the causative agent of columnaris disease that affects many species in many different environments. Lately there are strains identified that are very pathogenic. It should be quite an interesting subject for researchers in Africa, because I have seen signs of columnaris disease in most clarias and tilapia hatcheries that i have visited. Even for us here in Auburn, it a very problematic pathogen. Dr. Arias' lab including Dr. Haitham Mohammed from Egypt) has been working with this pathogen for some years now and from looking at the past venues of this conference, so have many other labs.

Flavobacterium est l'agent causal de la maladie de columnaris qui affecte de nombreuses espèces dans de nombreux environnements différents. Dernièrement il ya souches identifiées qui sont très pathogène. Il devrait être un sujet très intéressant pour les chercheurs en Afrique, parce que je ai vu des signes de la maladie dans la plupart des columnaris clarias et écloseries de tilapia que je ai visités. Même pour nous ici à Auburn, un agent pathogène très problématique. Le laboratoire du Dr Arias dont le Dr Haitham Mohammed de l'Egypte) a travaillé avec ce pathogène depuis quelques années maintenant et en regardant les dernières salles de cette conférence, ont donc beaucoup d'autres laboratoires.
