This is a structured expert-elicitation survey evaluating 67 control measures for salmonid rickettsial septicemia through Likert-scale scoring by nine Chilean aquaculture health managers. The study ranks measures by perceived effectiveness and expert agreement but does not provide empirical validation of efficacy or impact on disease outcomes in field conditions.
Cross-sectional expert-elicitation survey. Nine head fish health managers representing more than half of Chilean Atlantic salmon and rainbow trout production. Intervention: Expert scoring of 67 SRS control measures across biosecurity, mortality management, production practices, therapeutic, and vaccination categories. n = 9. Chile.
Biosecurity, mortality management, and production practice measures ranked highest with strong expert agreement Specific antimicrobial protocols (oral florfenicol, injectable oxytetracycline monotherapy, and combination florfenicol + oxytetracycline) reached high consensus among experts Vaccination strategies and other therapeutic measures exhibited substantially greater variability in expert agreement
No empirical measurement of control measure efficacy or impact on disease incidence or mortality Biosecurity, mortality management, and production practice measures ranked highest with strong expert agreement
This framework may inform aquaculture industry decision-making on SRS control priorities, but should not substitute for field trials or empirical outcome data. Practitioners should treat expert consensus as a guide for hypothesis generation rather than as evidence of efficacy.

Piscirickettsiosis (SRS) remains the main infectious disease affecting salmon aquaculture in Chile. This study evaluated expert perceptions of the effectiveness of SRS control measures and the level of agreement among industry professionals. A structured cross-sectional expert-elicitation survey was conducted with nine head fish health managers representing more than half of the Chilean Atlantic salmon and rainbow trout production. Experts scored 67 control measures using a 5-point Likert scale, and effectiveness and consensus were assessed using descriptive and variability metrics. Measures related to biosecurity, mortality management, and production practices ranked highest and showed strong agreement. Therapeutic and vaccination-related measures showed heterogeneous levels of agreement: several specific antimicrobial protocols (oral florfenicol, injectable oxytetracycline monotherapy, and combination florfenicol + oxytetracycline therapy) reached high consensus, while other therapeutic measures and most vaccination strategies exhibited substantially greater variability. The integration of effectiveness and consensus enabled classification of measures into priority tiers, consistently highlighting preventive strategies as high priority. These findings provide a structured, practice-oriented framework to support decision-making and reinforce the importance of management-based approaches for SRS control under field conditions.
