The Finnish Wildlife Agency is urging hunters to target the most abundant species of waterfowl such as mallard ducks, teal and goldeneye ducks. They are being asked to show more restraint in the hunt for species that are in decline, such as northern pintail, wigeon, pochard, garganey, tufted duck and coot.
There is also a nationwide ban on hunting bean geese and greylag geese in some inland regions.
Of the country's more than 300,000 active hunters, close to 100,000 are expected to turn out for the duck hunting season that runs through the end of December.
Saturday also sees the opening of the bear hunting season. The Wildlife Agency has issued 113 special permits for bear hunting for culling purposes in various parts of the country, and there is also a localized quota of 70 bears in reindeer herding areas. The season runs through the end of October.
The permits exclude cubs under the age of one, as well as females with young cubs.
