They will not harm corals in a reef environment, but are more suitable to FOWLR systems due to the fact that half of the cleaning crew may be added to the dinner menu. Tank mates should be considered carefully and can generally be other large predatory species (i.e., Groupers, large Angels, Puffers, Boxfish, Scorpion fish, Lionfish, Butterflyfish, etc.). This species should not be kept with shrimp, small lobsters, crabs, or any fish that can fit in its large mouth as they will quickly become snacks (large hermit crabs and snails should be fine). In addition to quality biological and mechanical filtration, an efficient protein skimmer is also recommended as Wolf Eels can be quite gluttonous when feeding and will have a large biological load on the system. It is the most species-rich genus of moray eels, many being predators and can be very hardy. They are not generally known to be jumpers, but should be kept in an aquarium with a hood or tight-fitting lid to help prevent their escape. Found widespread throughout the Atlantic, Indian and Pacific Oceans. Fisheries that harvest octopuses, urchins, and crab may remove prey resources that wolf-eel depend upon" (Jaglio 6).Wolf Eels require an aquarium of at least 90 gallons along with plenty of live rock for hiding and hunting (they love caves and crevices) they should also be provided with a fine, sandy substrate as they often rest on the bottom of the aquarium, laying in wait for prey to crawl or swim by. There were no wolf-eel present when surveyed. Trawler nets, which many fishermen use, are particularly damaging because they destroy rocky reefs where wolf eels reside. Conservationists and scientists suggest using alternative method of logline traps which won't damage the reefs.Īccording to Washington Department of Fish and Wildlife "the wolf eel appears to be a species that is sensitive to harvest and may be affected by competition with Pacific giant octopus and with fisheries During 1999, one area in the harvest zone was surveyed that once contained a large wolf-eel colony. Because wolf eels make their home in rocky reefs their homes are susceptible to damage from storms, pollution, trawler nets and other factors. Human pollution can affect wolf eel habitat, degrading it and making it uninhabitable. Wolf eel Washington Department of Fish & Wildlife Species & Habitats Species in Washington Bottomfish Wrymouth and eel Wolf eel Wolf eel (Anarrhichthys ocellatus) Wolf eel Category: Fish Related species groups : Wrymouth and eel Rarely caught incidentally in the commercial fishery off the Washington coast with otter-trawls. They are also often accidentally caught by fishers. No regional subspecies of the wolf eels have yet been assigned. Wolf eels are not at risk in British Columbia, but they still face threats like pollution, which can negatively affect the health of their environment (like kelp forests) and decrease prey populations. Distribution/Range Wolf eels are found in the North Pacific along the coast of North America from the Seas of Japan and Okhotsk, and the islands off the coast of southern Alaska to California. Wolf eels are often caught in crab traps or fishing nets. Wolf eels usually live for about 25 years. About two thirds were speared by skin divers and most of the others were caught by skiff fishermen. Actually a wolf fish, not an eel, the wolf-eel can be found as far south as San Diego in southern California, then northward to the Aleutian Islands in Alaska. Its uploader says the species is a wolf eel (Anarrhichthys ocellatus), a fish that is neither a wolf nor an eel but actually a kind of wolffish, a cantankerous-looking family named for their sharp. Crey's article discusses a breeding and release program for VPA.Ī survey from 1957-1961 stated that sport fishermen took an estimated 200 wolf eels a year. They swim by making deep S-shapes with their bodies, like a snake moving across the ground. There have been efforts to restore wolf populations in some areas. Wolf-eels live in shallow water as deep as 740 feet (225 m). Local populations of wolf eels have been wiped out in waters of many metropolitan areas as a consequence of fishermen and aquarium collectors as well as habitat destruction, pollution and accidental catching once eliminated from a site wolf eels will not return naturally (Creys).
