While fishers usually avoid human contact, encroachments into forest habitats have resulted in some conflicts. When pelt prices fell in the late 1940s, most fisher farming ended. However, their unusual delayed reproduction made breeding difficult. In the 1920s, when pelt prices were high, some fur farmers attempted to raise fishers. Conservation and protection measures have allowed the species to rebound, but their current range is still reduced from its historic limits. Their pelts were in such demand that they were extirpated from several parts of the United States in the early part of the 20th century. They have been trapped since the 18th century for their fur. įishers have few predators besides humans. Other Native American names for the fisher are Chipewyan thacho and Carrier chunihcho, both meaning "big marten", and Wabanaki uskool. Cree ocêk, Ojibwa ojiig) borrowed by fur traders. In some regions, the fisher is known as a pekan, derived from its name in the Abenaki language, or wejack, an Algonquian word (cf. The fisher is closely related to, but larger than, the American marten ( Martes americana) and Pacific marten ( Martes caurina). It is sometimes misleadingly referred to as a fisher cat, even though it is not a cat. It is a member of the mustelid family (commonly referred to as the weasel family), and is in the monospecific genus Pekania. Scavengers like vultures help prevent diseases from spreading by eating the remains of dead animals.The fisher ( Pekania pennanti) is a small carnivorous mammal native to North America, a forest-dwelling creature whose range covers much of the boreal forest in Canada to the northern United States. Predators keep populations of prey species from becoming too large. Carnivores play an important role in keeping ecosystems balanced. Most carnivorous plants consume insects, but some larger plants feast on small animals, such as frogs or mice. There are about 600 species of carnivorous plants, the most well-known being the Venus flytrap ( Dionaea muscipula). Carnivores also have a single stomach chamber and a simple digestive system, unlike herbivores, who often have a stomach with multiple chambers and a specialized digestive system. Additionally, many carnivores have relatively large brains. For example, most carnivores have sharp teeth adapted for capturing prey and tearing flesh. Carnivores vary in shape and size, but they often share similar traits. Animals whose diet is only about 30 percent meat are called hypocarnivores. Animals whose diet consists of about 50 percent meat are called mesocarnivores. Animals that get 70 percent or more of their nutrition from meat are called obligate carnivores or hypercarnivores. ![]() Carnivores are divided into three different categories based on what percentage of their diet consists of meat. Some carnivores, known as scavengers, feed on the carcasses of already-dead animals. Carnivores that have no natural predators are known as apex predators they occupy the top of the food chain. The animals that eat secondary consumers, like owls that eat rodents, are known as tertiary consumers. Many carnivores get their energy and nutrients by eating herbivores, omnivores, and other carnivores. An omnivore, such as a human, is an organism that eats plants and animals. Carnivores and omnivores occupy the third trophic level. Each food chain consists of several trophic levels, which describe an organism’s role in an ecosystem. ![]() An animal’s diet determines where it falls on the food chain, a sequence of organisms that provide energy and nutrients for other organisms. A carnivorous animal that hunts other animals is called a predator an animal that is hunted is called prey. A carnivore is an organism, in most cases an animal, that eats meat.
