Salmon

Marine farming zones 
Tassal has five marine farming zones, where the standard pen has a volume of 11,600 cubic meters and holds enough salmon to produce 120 tonnes once harvested. Salmon are kept in these large sea cages between 12 and 18 months and continue to grow until they are ready to be harvested at an average weight of 5.0 kg live weight.
 Eastern Zone, Okehampton Bay & Port Arthur
 Channel Zone, D'Entrecasteaux Channel
 Southern Zone, Dover & Huon River
 Western Zone, Macquarie Harbour

Freshwater hatcheries 
Tassal operates two hatcheries, with a third to be developed, it also has access to the selective breeding program operated by SALTAS on behalf of the Salmon industry in Tasmania.

Combined, they have the capacity to produce ten million smolt a year. These smolt come from broodstock from a Tasmanian-based industry selective breeding program. The Rookwood Road Hatchery and Nursery underwent an expansion in April 2016 to make it the biggest land-based salmon nursery in Australia with the capacity to produce approximately 8 million smolt per year. After 8–12 months at Rookwood Nursery, the smolt are transferred to sea.

On 31 December 2007, Tassal announced it was acquiring the assets and intellectual property of Superior Gold from the King Island Company, a wholly owned subsidiary of National Foods, for $26.5m.

On 1 July 2015, Tassal announced the acquisition of DeCosti Seafoods.

In September 2018, De Costi Seafoods, a wholly owned subsidiary of Tassal Group, acquired the land, assets and inventory of the Fortune Group prawn aquaculture business.

On 16 August 2022, Tassal Group was acquired by the Canadian aquaculture company Cooke Inc at 5.23 Australian dollars per share, or a total of 1.7 billion Australian dollars (1.19 billion US dollars). This was the third, highest offer Cooke Inc made to Tassal.

Partnerships 
In 2012, Tassal and WWF announced the “WWF Australia and Tassal Sustainable Aquaculture partnership".

Third party certification is currently provided by Aquaculture Stewardship Council (ASC), Best Aquaculture Practices, Global Salmon Initiative.

Environmental sustainability
In 2016, ABC News reported that Tassal would begin trials into farming three native seaweed species (Lessonia corrugata, Ecklonia radiata and Macrocysts pyrifera) alongside salmon and oyster on its farm leases to diversify the ecosystem of the farms. The macroalgae farming in the salmon cages also absorb pollution, such as chemicals and parasites.

Tassal became the 17th member of the Global Salmon Initiative in February 2018. In 2018, they moved towards 100% recycling of their hard and soft plastic.

Representation in media 
The investigative television program Four Corners aired an episode in October 2016 that focused on the Tasmanian Salmon aquaculture industry, with issues covered including environmental impact, health and sustainability practices of companies.</ref>

On 26 April 2021, Tasmanian author Richard Flanagan published the controversial non-fiction book Toxic: The Rotting Underbelly of the Tasmanian Salmon Industry, which claimed to expose a range of unethical practices in the Tasmanian salmon industry.

Macquarie Harbour 
During November 2016, non-compliances were detected at leases in Macquarie Harbour, where three salmon companies farm. Tassal alerted the EPA to issues and subsequently destocked its Franklin lease in the Harbour. The lease was fallowed for 18 months, during which time Aquaculture Stewardship Council was not pursued for the lease as there were no fish in it.

In May 2017, the ASC found Tassal had failed to comply with 19 requirements for ASC Certification.

In May 2018, Tassal established a joint venture with Petuna to farm in Macquarie Harbour. The goal was to improve stocking strategies, bio-security and allow longer fallowing periods to protect the environment.

Antibiotic use 
Concerns have been raised by Tasmanian community groups, such as the organization Marine Protection Tasmania, over the use of antibiotics by the company, particularly regarding the fact that there is a legally required 1000 degree day antibiotic withdrawal period before a farm salmon is slaughtered, but "wild" salmon that is fished by the public may still be contaminated with antibiotic residue. A monitoring report by the Environment Protection Authority Tasmania (EPA) that was published in July 2022 found that after heavy antibiotic use in response to a vibrio outbreak in Tassal's Sheppards lease in January of that year, flathead salmon caught  away from the boundary of Tassal's lease contained levels of antibiotics above the reportable threshold. Additionally, the World Health Organization has warned that antibiotics misuse contributes to antibiotic-resistant organisms developing, and that vaccination ought be used to prevent misuse. Tassal attempted to prevent the 2022 report, as well as another antibiotic residue monitoring report from September 2020, from being released to the public by the EPA.

In 2017 Tassal confirmed its use of the antibiotic oxytetracycline, which was not used in humans in 2018 in Australia, and was rated as low importance by the Australian Strategic and Technical Advisory Group on Antimicrobial Resistance.

Antibiotic use is audited annually by the ASC, whose standards forbid the use of antibiotics from the World Health Organization list of Critically Important Antimicrobials for Human Medicine.
