Fishers

The fisher (Martes pennanti) is a fascinating furbearing animal, mostly nocturnal by nature and rarely observed by humans. These animals can be observed during the day on rare occasion, however. Many people referred to this creature as the “fisher cat” but this is incorrect. Fisher are an active and aggressive member of the Mustelidae (weasel) family and are in no way related to felines. Using large trees with cavities as den and dwelling sights, Fisher require mixed hardwood/softwood forests as suitable habitat. Their diet consists of squirrels, rabbits, birds, mice & voles, frogs, porcupine and occasionally tree masts and fruits.

Though a natural and healthy population of fisher once called Connecticut home in the 1800s, the population declined dramatically due to deforestation, agricultural clearing and unregulated take of the animals. Well into the 1900s, fisher were considered extinct from their natural range throughout Connecticut. However, through regulation and management of both the animals and habitat, the fisher has made an astounding natural recolonization in Northeast Connecticut. In 1988, the state Department of Environmental Protection initiated a project to introduce fisher to northwest Connecticut. According to the Connecticut DEEP, “Fishers did not recolonize suitable habitat in northwestern Connecticut because the region was isolated from a source population. Fishers were rare in western Massachusetts and the developed and agricultural habitats of the Connecticut River Valley were a barrier to westward expansion by fishers in northeastern Connecticut … Fishers were obtained by first trapping wild turkeys in Connecticut for release in Maine. Funds from reimbursement for the turkeys were used to purchase fishers caught by cooperating trappers in New Hampshire and Vermont.” Thanks to the hard work and efforts of the men and women involved in this project, a healthy population of fisher now extend throughout the suitable habitat range in northwestern Connecticut.

Fisher are extremely aggressive and are occasionally the culprit in the attack and death of small livestock and poultry. Though nuisance complaints for fisher are uncommon, the need to have a fisher removed does become reality for some. These animals can be taken during the regulated fur trapping season for fisher which typically opens in mid-November and closes on the last day of December.
