Ausvet has published another article in the peer-reviewed scientific press based on work conducted in Chile in 2018.
This Aquaculture article entitled ‘Effectiveness of vaccination for the control of salmonid rickettsial septicaemia in commercial salmon and trout farms in Chile’ is freely available for download until the 14th of March, 2020 here.
The work published in this article, lead by Jonathan Happold, is part of a large research project on the epidemiology of salmonid rickettsial septicaemia (SRS) in salmon and trout farms, conducted in 2017-2018 in Chile. It shows that observational studies of vaccine effectiveness can help to support management decisions to control infectious diseases in aquaculture. In Atlantic salmon and rainbow trout, some freshwater vaccination regimens were better than others in controlling the disease. However, we did not observe a beneficial effect of booster vaccinations for SRS in the seawater phase of the production.
Ausvet consultants are grateful to all stakeholders in Chile for their support, especially the salmon producing companies.
