More than 700 hunters have a chance to bag a moose in this first part of the season.
The season is broken up into four sections with the hunt beginning today in Northern and Eastern Maine.
It will continue in other sections of the state through November.
A total of 2080 permits were issued this year which is 60 fewer than last year.
Game officials said the moose population has declined in recent years, partially because of parasites that can cause health problems. Fewer permits are issued in areas where the animals have been struggling the most.
1,609 permitted hunters bagged a moose in 2016, which is about a 75% success rate.
