Seafood company Sanford has achieved a record full-year profit fuelled by a strong performance of its aqua-cultural business

It's recorded a net profit of 63.7 million dollars for the year ended September - three times more than the year earlier.

Cash flow's up 85 percent on last year, with the company's salmon and mussel business exceeding expectations.

Sanford's Managing Director David Mair says the gain in cash flow's been used to cut the company's debt by nearly half.

He says 92.1 million dollars has been paid back, meaning the company now owns itself, rather than the banks.
