Use of regulatory data to describe and identify risk factors for salmonid rickettsial septicaemia in Chile, 2011–2017

Abstract

The bacterial disease salmonid rickettsial septicaemia (SRS) has caused substantial economic losses in the salmonid aquaculture industry, particularly in Chile. Increasing understanding of the epidemiology of this disease is important for improving the productivity and sustainability of the industry: by identifying important influences on disease occurrence, interventions can be identified and optimised to minimise disease occurrence and its effect on the industry. This study aimed to describe SRS-attributed mortality across production species, time and space in the Chilean salmonid industry; identify risk factors for mortality attributed to SRS; and generate additional hypotheses for future..
