Primarily a carnivore. The fisher is one of the few animals that will kill a porcupine. It will also eat anything else it can overwhelm; rabbits, squirrels, chipmunks, birds, insects, reptiles, fish, crayfish and carrion; some berries, seeds and tips of ferns.
The fisher is a wide-ranging, year round hunter, preferring to venture out at night. Because it has few natural enemies, the fisher population has remained stable. A female will produce one litter of 2 – 3 offspring a year.
