2019 is the lowest since the measurement began in 2012
Sernapesca reports that the downward trend in the use of antibiotics in the salmon industry continues

In 2019, the antimicrobial treatments carried out by the salmon industry in Chile used the equivalent of 334 tons of active ingredient, which when calculating the antimicrobial consumption index "ICA" (ICA = percentage relationship between the amount used of antimicrobial and harvested tons of biomass) corresponds to 0.034%.
This is the main conclusion of the latest report on the use of antimicrobials published by the National Service of Fisheries and Aquaculture (Sernapesca), and which analyzes the year between January and December 2019. In the publication, it is highlighted that the ICA for 2019 is the lowest since the measurement began in 2012, when the index returned 0.041%, and notably lower than 2015, when it reached 0.063%. Since that year, a continuing downward trend has been reported, despite the increase in harvested salmonid biomass.

The report also indicates that 96.5% of the antimicrobials were administered in the productive phase of the sea and only 3.5% in the freshwater phase. The most used active principle in fresh water (70.1%) corresponded to Oxytetracycline, while in sea water it was Florfenicol (98.6%).
In the analysis by species, Atlantic Salmon explains most of the treatments, with 90.8% in the sea phase. Regarding the diagnoses, 91.4% of the antibiotics used were to treat Piscirickettsiosis (SRS), followed by 7.2% for Renibacteriosis (BKD) and 1.4% associated with Tenacibaculosis.
The report indicates that with respect to sea treatments, 58.1% was in the Aysén region, 35.9% in the Los Lagos region and 6% in the Magallanes region. In addition, the report provides data on the amount of active ingredient administered by ACS (Agrupación de Concesiones de Salmónidos) in 2019.
All this information, including graphics and greater detail, is already available on the Service's website, in the "Management Results" section.
Within the strategic framework of reducing the use of antimicrobials, this year Sernapesca has implemented the Program for the Optimization of the Use of Antimicrobials called "PROA-SALMON", a program that is part of a new voluntary certification tool for producers whose main objective is to further reduce the use of antibiotics through a comprehensive disease management plan.
It is expected that in the last quarter of this year the first centers will be certified under this innovative modality, which in addition to certifying the center free of antimicrobial use, will also recognize the culture center that made a limited use of these active ingredients. This is reinforced by a chain of verification milestones throughout the fattening cycle by accredited third parties and Service officials.
Finally, during the month of November and within the framework of the world week of awareness about the use of antimicrobials, organized by the OIE, FAO and WHO, we will hold a virtual seminar in which we will address good practices in the use of antimicrobials in the sector, the new PROA certification and the data on use during this year, with the aim of continuing to advance in sustainable aquaculture.
