Fish oil manufacturer SeaDragon has more than doubled annual sales, but it's posted a loss of $2.8 million.
The company says the result reflects investment in a new Omega 3 fish oil refinery and a one-off non-cash inventory write-down of $905,000.
Its profit last year was $431,000.
SeaDragon says it's on track to commission the new refinery in Nelson later this year.
