An industrial-scale study on the impact of vaccination upon rainbow trout performance

the effect of intraperitoneal (ip) vaccination upon the performance of rainbow trouz (n=161) maintained under commercial production conditions (aerated spring water, 9,8ºC, 150 L/min), was evaluated over a 7-week period. Vaccine impact was examined with reference to control (n=1683) and injected control (sterile filtered water; n=1537) animals. All groups were run in triplicate (i.e., n≥500 fish per group). Animals were fed to saturation twice daily. Vaccination supressed (P<0.05) growth in weight over the entire period of study when compared to control treatments. A corresponding decline in specific growth rates (P<0.05) over the first 29 d of the trial, was also observed for vaccinated fish. Feed conversion efficiencies and feed ratio were similarly negatively affected in vaccinated animals for 29 d post-vaccination (P<0.05). The vaccine caused abdominal adhesions although no dufferences were observed in body composition.
