Norwegian salmon market sources expect the price of fish for next week delivery to increase by NOK 3-4 (€0.29-€0.39/$0.30-$0.40) on average for the main 3-6 kg industrial sizes.

"The market has, however, not settled yet," one market source said around 2pm local time in Norway on Friday.

An exporter confirmed the price rise, and added that any fall in price will be significant when the time comes.
