Global farmed salmon producers significantly reduced antibiotic use over seven years, GSI report finds

May 12, 2020 — Seven years of data from more than 50 percent of the world’s farmed salmon sector is featured in the latest annual sustainability report from the Global Salmon Initiative (GSI).

Released on 11 May, the report’s data covers 15 key indicators – 10 environmental and five social – impacting salmon aquaculture operations worldwide. The new issuance, which highlights data through 2019, reveals some promising sector trends, GSI said, including a 50 percent reduction in the use of antibiotics over the past seven years, as well as a more holistic, collective approach to preventing and managing sea lice.

Is Fish Slime an Untapped Resource?

April 18, 2019 — Researchers seeking potential replacements for current antibiotics losing their effectiveness against multidrug-resistant pathogens have identified a possible option in the protective mucus that coats young fish.

The team, led by principal investigator Sandra Loesgen at Oregon State University, presented their findings at the recent meeting of the American Chemical Society Spring 2019 National meeting and Exposition in Orlando, Florida.

The bacteria is seen as a promising antibiotic to counter known pathogens, even dangerous organisms such as the microbe that causes MRSA infections. MRSA, or methicillin-resistant Staphylococcus aureus, is a bacterium that causes infections in different parts of the body and is resistant to come commonly used antibiotics.

The protective mucus coating young fish is a viscous substance that protects fish from bacteria, fungi and viruses in their environment, trapping the microbes before they can cause infections.

The slime is also rich in polysaccharides and peptides known to have antibacterial activity.

According to Molly Austin, an undergraduate chemistry student in Loesgen’s laboratory, the fish mucus is interesting because the environment the fish live in is complex. “They are in contact with their environment all the time with many pathogenic viruses,” she said.

Chilean salmon industry pledges 50 percent reduction in antibiotics usage

March 20, 2018 — At Seafood Expo North America on Monday, 18 March, companies representing about 80 percent of the total production of salmon in Chile vowed to reduce their use of antibiotics and seek a “Good Alternative” rating from the Monterey Bay Aquarium’s Seafood Watch program by 2025.

Members of the Chilean Salmon Marketing Council, which include Cermaq Chile, MultiExport Foods, Australis, Salmones Camachaca, Blumar, Ventisqueros, Salmones Austral, Marine Farm, Salmones Magallanes, and AgroSuper (which owns Aquachile, Los Fiordos, and Verlasso), have all pledged to pursue a 50 percent reduction in their use of antibiotics by 2025.

The partnership between SalmonChile, the Chilean Salmon Marketing Council, and the Monterey Bay Aquarium will formally be known as the Chilean Salmon Antibiotic Reduction Program (CSARP). Norway-based Mowi’s Chilean operations will also participate in the initiative, SalmonChile CEO Arturo Clement told SeafoodSource at the event.

Griffin said the issue of antibiotic use has been a major one for the Chilean salmon industry for years, and that when he took over as head of the marketing council in December 2017, curbing antibiotic use was a top priority for him, as a means to achieve higher recognition in Seafood Watch’s seafood ranking system, which rates seafood as either a “Best Choice,” a “Good Alternative,” or as food to “Avoid.”

Court Says Antibiotic Use in Chilean Fisheries Should be Public Knowledge

September 20, 2015 — The organization Oceana won a landmark case last week against the Chilean government. The appeal, which went up against the National Fisheries and Agricultural Services (Sernapesca) found the judges unanimously decided that the Council for Transparency had to release its data regarding antibiotic usage in Chilean salmon.

The lawsuit began some time back, when reports were released that showed staggeringly high amounts of antibiotic usage within Chilean salmon fisheries. Salmon in Chile is susceptible to a disease called Piscirickettsiosis which can cause hemorrhaging, organ failure and death in salmon. A report by Reuters earlier this year showed Costco, along with a number of U.S. chains, had cut the amount of Chilean salmon it was buying in favor of salmon from Norway – which generally uses fewer antibiotics (although it should be noted that numbers for last year’s antibiotic use were not available from Norway).

However, those within the industry contest this accusation. They say the antibiotics used save these fish and heal them from the bacteria. They maintain that the fish are then weaned off these medications until no traces remain, before being shipped to market. Ricardo Garcia, the chief executive at Camanchaca, a large salmon producer in Chile, told Reuters that, “The final product consumers eat has no antibiotics.”

Access Granted to Chile’s Salmon Farming Antibiotic Use Info

CHILE — September 14, 2015 — Oceana has been granted access to information on Chile’s salmon farming antibiotic use between 2009 and 2013, following a unanimous ruling by Santiago’s Court of Appeals.

“We are pleased to hear the reversal of an incorrect ruling by the Transparency Council. Clearly, this is public information as it allows people to make decisions on fundamental issues, such as health and the environment, in addition to making scrutiny on whether the Government is effectively controlling this industry or not,” stated Alex Muñoz, Vice President for Oceana in Chile.

In July 2014, Oceana resorted to the Transparency Council after 50 salmon farms refused to reveal the amount and type of antibiotics used by them, on the grounds that this would entail “a competitive and commercial risk.”

The Transparency Council agreed with the salmon farms and declared that the National Fishery Service is not required to reveal disaggregated figures.
