Tilapia Lake Virus Conference Call – Friday July 28

The National Aquaculture Association (NAA) invites you to participate in an information-sharing conference call between U.S. tilapia growers (fry, fingerlings or broodstock), live importers, and live shippers of market-ready live fish or fingerlings and USDA APHIS Veterinary Services Aquaculture Program.

The toll-free conference call will occur on Friday, July 28, 2017, at 3:00 PM Eastern. There is no registration for the call and the call will not be recorded.

The call-in information is: Dial-in phone number: 712-775-7031. Access Code: 664-518-980.

The topic of this call will be Tilapia Lake Virus. Tilapia Lake Virus (TiLV) is an emerging disease that has been reported in at least eight different countries around the world where tilapia are produced. This disease appears to have the greatest impact on fingerlings, with losses as high as 90% and appears to be spread by animal movement. To date, there are no reported cases of TiLV in the United States.

Because of the world-wide threat of this disease and the significant impact on tilapia production, it is anticipated that this disease will be added to the list of internationally reportable diseases by the World Organization for Animal Health (OIE; see: http://www.oie.int/en/animal-health-in-the-world/oie-listed-diseases-2017/) in the near future. This could mean that exports of live tilapia from the U.S. will require export health certification that states animals are free of this disease. NAA and APHIS are committed to working together to protect U.S. aquaculture and maintaining secure markets for aquatic animals and their products.

In preparation for the call, APHIS has provided three TiLV related questions for you to consider prior to the call.The questions are:

Do you feel there is a need for our own import health requirements of live tilapia entering the United States from countries known to [...]

NAA Action Alert: Tilapia Lake Virus

Tilapia Lake Virus

Tilapia Lake Virus (TiLV) is a highly pathogenic virus that poses a significant threat to cultured and wild stocks of tilapia.  Little is know about effective control methods.  Infected fish often show loss of appetite, slow movement, dermal lesions and ulcers, ocular abnormalities, and opacity of the lens (i.e., cloudy eyes).  The disease has been confirmed in some countries in Africa, Asia and Latin Americal.  The impact on infected tilapia populations is significant with desease-associated mortality as high as 90%.
