Fisher Cat Welfare: Forest Carnivore and Trapping Victim

The fisher is a large mustelid of North American forests whose welfare is significantly affected by trapping, reforestation after logging, and the availability of prey in managed forest landscapes.

Key Facts

Fishers were reintroduced to much of their former range in the northeastern US after near-extinction from overtrapping in the 20th century
Despite the misleading name, fishers rarely eat fish and primarily prey on snowshoe hares, porcupines, and squirrels
Fishers are one of the few predators capable of killing porcupines by attacking their unprotected faces
Rodenticide poisoning from consuming poisoned rodents in timber plantation areas causes significant mortality
Female fishers have a remarkable delayed implantation, giving birth in March and entering oestrus again within days

Welfare Considerations

Fisher welfare is primarily threatened by trapping, both targeted and incidental. Leghold and Conibear traps cause acute trauma, and mortality rates for non-target species caught in fisher traps are significant. Rodenticide poisoning from anticoagulant use in cannabis and timber plantations causes internal bleeding and protracted suffering. The social complexity of fishers, which communicate through scent marking and vocalisation, suggests meaningful welfare interests that are poorly accounted for in current management frameworks.

What You Can Do

Support campaigns for trapping reform that prioritise humane capture methods in fisher management
Advocate for restrictions on second-generation anticoagulant rodenticide use in forested landscapes
Support reforestation initiatives that create mature forest habitat essential for fisher denning
Donate to wildlife rehabilitation programmes that care for injured fishers and other mustelids
