Tassal head of sustainability and fish health Linda Sams said the proposed expansion would be just the second for Tassal in the past decade and would mark a transition into offshore farming, reports NTNews.
The four 45-hectare leases would be located 1.8km west of Wedge Island within an 863ha zone.
Ms Sams said faster moving currents and cooler water temperatures would be beneficial for the salmon.
“It’s good for the fish, and managed well it will be good for the environment as well,” she said.
