Norwegian seafood manufacturer Marine Harvest has proposed an extraordinary dividend, having booked its “best second quarter in history”.

The company said operating profit rose to NOK901m (US$147.9m) in second quarter, up from NOK231m in the comparable three-month period last year. Sales rose to NOK4.44bn, up from NOK4bn driven by higher pricing, which more than offset a 20% drop in fish harvest volumes.

The world’s largest producer of farmed salmon proposed an extraordinary dividend of NOK0.05 per share.

Marine Harvest lowered its 2013 production outlook to 335 000 tonnes, but ramped up its full-year production estimates for 2014.

“The future prospects for MarineHarvest are also good. We are ramping up production estimates with 55 000 tonnes in 2014, to 390 000 tonnes,” CEO Alf-Helge Aarskog said. “I am very encouraged by the strong market outlook in Europe.”
