Tassal operates two main hatcheries

Tassal operates two main hatcheries that have the capacity to produce 5.5 million smolt a year. These smolt come from broodstock from an industry selective breeding program; four million of these smolt are kept at the state-of-the-art Rookwood Road Hatchery. After 12 months at Rookwood Road these smolt are transferred to sea.

Tassal has six marine regions, where the standard pen has a volume of 11,600 cubic meters and holds enough salmon to produce up to 140 tonnes once harvested. Salmon are kept in these large sea cages between 14–21 months and continue to grow until they are ready to be harvested at an average weight of 5.0 kilograms live weight.

Tassal has three processing sites including a smokehouse that produces an average of 15.4 kg finished product per minute or 3,048 tonnes every year.
