Tassal seeks backdoor approval to continue use of seal bombs on ASC certified farms

A request to permanently allow Tassal salmon farms to use underwater seal bombs – despite being prohibited by the Aquaculture Stewardship Council certification – was recently quietly published on the ASC website.

The variance request was submitted by auditors, SCS Global, on behalf of their client Tassal, and aims to exempt farms from ASC criteria intended to protect wildlife from harm caused by acoustic deterrent devices. If approved, it will mean Tassal can continue to market their ASC product to shoppers as “responsibly farmed.”

The ASC Standard has a “zero” tolerance use of acoustic deterrent devices (ADDs) or acoustic harassment devices (AHDs) during the farming cycle. Seal bombs are explosive pyrotechnic devices that detonate below the surface producing intense impulsive sound frequencies that can cause pain to seals, porpoises, and whales. The ASC considers seal bombs ADDs/AHDs.

The variance request comes after auditors failed to penalize Tassal’s use of seal bombs on ASC farms for nearly ten years; instead audit reports state the farms are “compliant” with the “zero” tolerance criteria. Audit reports dating back to 2014 reveal that auditors relied on written company declarations that ADDs, and AHDs were not used on farms.

Numerous studies find seal bombs can cause hearing loss, bone fractures, soft tissue burns, other physical trauma and potentially death to seals as well as other marine life. A 2018 Tassal report, accessed via Right to Information, detailed the grizzly death of a seal due to a bomb being thrown outside a pen five meters from a seal.

RTI documents (2 ; 3 ; 4) show Tassal has used nearly 60,000 seal bombs since January 2018. According to Tassal’s website, 1,006 seal bombs were used at Tassal farms from December 2022 to November 2023. Despite these numbers, last month Tassal farms Creeses Mistake and West of Wedge were regranted ASC certification.

The timing of the request also coincides with the upcoming ASC surveillance audit for Okehampton farm which was recently exposed as experiencing mass fish deaths.

Globally, greenwashing exposés and scrutiny of farmed salmon certifications is increasing. Last month, conservation groups lodged a formal complaint to the Australian Consumer and Competition Commission (ACCC) over the use of “responsibly sourced” claims made on Tasmanian salmon products linked with the Best Aquaculture Practices and GLOBALG.A.P. certifications in Macquarie Harbour where the industry poses a catastrophic threat to the endangered Maugean skate.

If Tassal’s request is approved, the ASC will no longer hold a higher animal welfare bar for seals than the RSPCA who, despite the many studies demonstrating negative welfare impacts, allows the practice of seal bombs on RSPCA endorsed salmon farms.

Trish Baily, VP at Tasmanian Alliance for Marine Protection, and Tasman Peninsula for Marine Protection representative said:

“Since 2014, stakeholders in Tasmania have engaged with the ASC auditing process in good faith, raising numerous concerns, including the regular use of deterrent devices such as seal bombs on Tassal farms. Yet the auditors have routinely ignored or dismissed stakeholder objections. Despite the globally renowned ASC certification having a zero tolerance on the use of seal bombs, Tassal has consistently received a stamp of approval from auditors and this makes a mockery of the certification process.

Alistair Allan, Marine Campaigner at the Bob Brown Foundation, said:

“This is how certifications become meaningless. Tassal is part of attacking native wildlife and destroying Tasmania’s marine environments, yet it remains certified despite engaging in a practice that is explicitly not permitted by the ASC. With this latest move, consumers can now see that the whole certification scheme for farmed salmon is a sham.

Jessica Coughlan, campaigner at Neighbours of Fish Farming, said:

“We call on ASC to reject the request for Tassal to continue its harm to our native protected seals. Consumers should be outraged that Tassal farms have been allowed to get away with the use of seal bombs for the past ten years despite the ASC prohibiting it. The certificates from the eight ASC Tassal farms should also be revoked so long as the practice of using firearms and explosives in our sensitive waterways continues.

Kelly Roebuck, SeaChoice representative from Living Oceans, said:

“The ASC Standard might look good on paper, but it often isn’t applied as such due to loopholes. From Canada to Chile to Scotland to Tasmania, ASC variances can result in criteria exemptions that enable salmon farms to be certified that would otherwise be ineligible. Shoppers expect certifications to live up to their ‘responsible’ claims, not cater to industry norms.

The ASC Salmon Standard states:

Indicator: 2.5.1 Number of days in the production cycle when acoustic deterrent devices (ADDs) or acoustic harassment devices (AHDs) were used Requirement: 0

Tassal seal bomb numbers:

  • Tassal dashboard – reports 1,006 seal bombs used from December 2022 to November 2023.
  • RTI documents (2 ; 3) and NRE reporting – shows Tassal has used nearly 60,000 seal bombs since January 2018.

Tassal report (RTI) on seal death due to a bomb being thrown outside a pen five meters from a seal: “After the cracker went off, the seal surfaced. The seal was showing blood and blowing a lot of bubbles before sinking and [was] not sighted again.”

Studies on seal bomb impacts: Kerr and Scorse (2018) details sea lions with “evidence of intra-oral explosion, including traumatic injury to bone of maxilla and mandibles, soft tissue burns and prolapsed eye balls”. The study also lists potential impacts to fish, whales, and other marine life. A Canadian government study found seal bombs “could potentially cause permanent hearing loss in a seal or sea lion at a range of about 10 meters”. Studying the Monterey Bay Harbor porpoise, Simonis et al. 2020 suggests seal bomb noise exposure is a potential threat regarding hearing damage and behavioural effects such as displacement and foraging disturbance. A NOAA study that tested a variety of seal bombs determined they can cause severe to moderate injury to dolphins when detonated within a zero to four metre distance.
