Yersinia ruckeri Bacterin

For Veterinary Use Only

This bacterin contains formalin inactivated cultures of Yersinia ruckeri serotype I (Hagerman strain).

USE: For the vaccination of healthy salmonids as an aid in the prevention of Enteric Redmouth Disease, caused by Yersinia ruckeri serotype I.

VACCINATION PROGRAM: This bacterin has been shown to be safe and effective when administered by immersion to healthy salmonids 2 g or larger. Vaccination should precede exposure of vaccinates to the disease agent by at least 250 degree-days (number of holding days multiplied by the mean water temperature [°C] during the period).

Dosage and Administration

Each liter of undiluted bacterin is sufficient to vaccinate 100 kg of fish. To use, add 1 liter of bacterin to 9 litres of clean hatchery water to make a 10 liter vaccine bath. Net, drain and immerse 5 kg batches of fish (≥ 2 g in size) in the bath for 30 seconds. The bath may be reused up to 20 times before discarding. Withhold food from fish 24 hours prior to vaccination.
