Dear Melshior;
It is highly advisable that you seek help from a veterinary diagnostic lab to identifying
the cause of these lesions, and/or any increased mortality. The pictures you shared could
be caused by a number of bacteria, viruses, fungi, or other pathogens. Without this
information, it’s impossible to plan prevention, control or eradication programs, and your
losses will only increase with time.
I would recommend you contact the Ghanaian Veterinary Services (see
http://www.e-agriculture.gov.gh/index.php/about-mofa/technical-services/vet…).
While they primarily deal with livestock diseases, many of the diagnostic assays they
will be able to perform (e.g. bacterial culture, histopathology, etc.) will help narrow
down, or identify the cause. They may also be able to recommend another vet DX lab in the
region that could provide additional diagnostics, if needed.
Regards,
Dave

Dear Avor
We have he'll lot of diseases in Ghana and the mortality is everywhere except some
farms who went on for vaccination for Strep. Even after vaccination they still face
mortality but not much like others.
We have columnaris, aeromonas, Streptococcus, klebsiscella etc etc bacteria, saprolegnia,
fish lice etc.
Looking at the pictures I fear more now, aeromonas also looks little bit near to those
symptoms but fin rot is dominant when aeromonas is there.
These symptoms are matching with the latest pics released for TILV.
Let's not conclude, I will forward this mail to a expert who came to Ghana two days
back and he has PCR with him. He will confirm the disease if it is TILV.
Please give your contact details
With Regards
Naga Murali

Subject: Could this be a sign of tilapia lake virus?
Clinical signs on moribund farmed tilapia from Volta Lake Ghana… what do they tell one
?
Hi William
Every month during sampling I see this sign on at least two fishes, I record mortality of
50pieces on average daily.
There is no single day, were we don't record mortality on lake Volta around
Akosombo.
Kindly find attached photos
Could it be Tilapia Lake Virus?

Salut Guillaume
Chaque mois lors de l'échantillonnage, je vois ce signe sur au moins deux poissons, je
note la mortalité de 50 pièces par jour.
Il n'y a pas un seul jour, si nous ne enregistrons pas la mortalité sur le lac Volta
autour d'Akosombo.
Veuillez trouver ci-joint les photos
Peut-il être Tilapia Lake Virus?
Cordialement
