A large stock of capelins have been found in Faroese fjords of late and scientists believe that the fish probably swam there from Icelandic waters, RÚV reports. Iceland’s capelin stock has been in decline over the last two years, likely due to rising ocean temperatures.

As a result, the Marine and Freshwater Research Institute (MFRI) will not permit fishing of the species this coming season. Capelin is the second most important export species of fish in Iceland after cod.

Scientists with the Department of Fisheries and Oceans say late spawning for capelin had a significant impact on numbers.
