Main Characteristics
Fishers are medium sized mammals that have a body length between 47 and 75 cms (18.5 - 30 inches), a tail length between 30 and 42 cms (12 - 16.5 inches) and they weigh between 2 and 5 kgs (4.5 - 11 lbs).
During the winter months they have a thick, glossy coat that is deep brown/black in colour but during the summer months they are lighter brown.
Habitat
Fishers can be found in forested areas of North America.
Diet
Fishers mainly feed on small mammals, birds, insects, nuts, berries and carrion.
Breeding
Fishers breed in late March or early April and implantation is delayed for 10 months until January or February the following year. After a gestation period of approximately 50 days, females will give birth to 1 - 6 kits then 7 - 10 days later they enter estrus and the breeding cycle begins again.
At birth the kits are blind and helpless, but after 3 weeks they begin to crawl around in the nest. At 7 weeks they open their eyes and at 8 weeks they begin to climb. They are weaned at 8 - 10 weeks and when they reach 4 months old they begin to become intolerant of one another.
After 5 months their mother pushes them out on their own and by the time they are a year old the youngsters have established their own ranges.

Humans are predators of Fishers.
