Norwegian salmon prices have risen to on average of more than NOK 70 (€6.49/$7.21) for the largest fish, amid reduced availability.

Traders said this should continue next week with a lower harvest in prospect.

"There is less fish available, and a smaller harvest day next week. Prices are rising," one exporter told IntraFish.

Exporters report larger fish, so-called 6-plus sizes having sold for NOK 71 (€6.58/$7.31)/kg
