Vaccinating tilapia ... Workers at Min-kota Fisheries are inoculating these fingerling fish against streptococcus in preparation for shipment to a Minnesota facility which has experienced an outbreak of the deadly disease. In back are Donnie Ehlers and Devon Ehlers. Around the fish table are, from left: Julie Seager, Kit Bramblee, General Manager Pat Seager, Brandy Seager, Jay Calhoon and Jason Harry.
"It's a very tedious process, but tolerable," said Pat Seager, Min-kota Fisheries general manager, about inoculating 40,000 fish per batch before shipment to a facility that has been exposed to a deadly fish disease.
The disease, called streptococcus, can wipe out at least 40 percent of a major fish growing operation. The disease, though, does not affect humans. Any infected fish within harvestable size can be, and are, processed for human consumption.
Even the inoculation itself is species specific. It is a "killed" vaccine and does not harm people.
