Abstract:
We present here the first evidence of the achievement of an effective protection against pasteurellosis of 50 mg gilthead seabream using a toxoid-enriched whole-cell bacterin, commercialised as DI vaccine, by dip or bath procedures. The relative percent survival (RPS) values were slightly higher by the dip method (84-90) than by prolonged bath (77-80). On the basis of these results, we recommend a first immunization when larvae are around 50 mg and a booster immunization when fish reach 2 g body weight.
