It has been suggested that the longer snout may confer advantages for foraging as mountian whitefish are primarily bottom feeders. A fierce predator with a diverse appetite, the burbot is capable of swallowing prey nearly their own size. An analysis of homogenization and differentiation of Canadian freshwater fish faunas with an emphasis on British Columbia. WYSIWYG Freshwater Fish now available in the Diver's Den®! Dextrase, A. and N. Mandrak. Adult inconnu are fish eaters while juveniles may feed on insect larvae and planktonic crustaceans. An ancient species, white sturgeon are both long-lived (over 100 years) and large (growing up to six metres and 800 kg). In recent decades, ocean survival of steelhead, particular those populations in the Fraser River watershed have declined significantly. Typical range in length for adults: 40 to 55cm Maximum: 150cm, Typical range in weight for adults: 0.9 to 2.3kg Maximum: 21kg. Typical range in length for adults: 50-85cm Maximum: 120cm, Typical range in weight for adults: 1.4-6.8kg Maximum: 21kg. . Rainbow trout demonstrate significant variation in form, ranging from the sea-run steelhead to the the massive "Gerrards" of Kootenay lake which, at 9kg, have a mass nearly four times that of more common rainbow trouts. Lake whitefish were also introduced at some time in the past into the Kootenay and Okanagan drainages. Others may migrate from natal stream to larger freshwater bodies while a third variation migrates to saltwater during winter months to feed prior to returning to freshwater. This set of keys is an attempt to provide rapid and dependable field identifications of BC freshwater fish. Extensive volcanism from 23 â 3 mya helped to produce the heavily sculpted waterscapes of the central interior of BC. .
Typical range in length for adults: 60 to 90cm Maximum: 150cm, Typical range in weight for adults: 1 to 5kg Maximum: 33kg. Typical range in length for adults: 30 to 65cm Maximum: 70cm, Typical range in weight for adults: 0.9 to 1.8kg Maximum: 7kg.
��|�����_��)�N=B����DP8B2b��J$-�V�7R This range of life histories is known to exist within the same river basin and even within the same populations. Their sizes and lengths vary significantly depending on the life history with anadromous bull trout being hte largest. The mountain whitefish favours cold deep lakes and swift running clear streams with deep pools. h��UMO�0�+�����/ !��K-��qH!E+m�R����&V���o�L����%��( �'�'k-0����lRL�X1��5�"�EK�IP���ɫ� �S F
The least diverse are the trout-perches (Percopsidae), pikes (Esocidae), and cods (Gadidae) each with one species. The Mackenzie River system is the largest in BC at about 260,000 km2 and the Queen Charlotte Islands is the smallest drainage area at 14,500 km2. As the name suggests, the northern pike are native to some of the more northerly river systems in the province, including the Yukon and Liard, although it has also been found in the Kootenay and Pend d'Oreille systems in southern BC as a result of unauthorized transplantation. Journal of Fisheries and Aquatic Science 61: 68-79. In many provincial lakes where black crappies have been found native populations of small fish have largely disappeared although it is uncertain whether this is due to direct predation or competition for resources. 1994. Populations are maintained through active stocking programs, sterile females are stocked to ensure there is no risk of resident populations becoming established. Mountain Whitefish (Prosopium williamson), Typical range in length for adults: 15 to 25cm Maximum: 70cm, Typical range in weight for adults: 0.05 to 0.2kg Maximum: 2.9kg. The previous handbook on freshwater fishes was printed in 1967, and with so many changes to the ichthyofauna ofBC, it is necessary to print a new handbook to summarise freshwater fish diversity in … BC Ferries River Levels Sunrise/Sunset Tides Weather. This map provides information on the 800+ lakes stocked for recreational fishing. For conservation information relating to Sturgeon, please visit the Fraser River Sturgeon Conservation Society. [Date Accessed]. Please review the document Releasing White Sturgeon - The Gentle Way PDF [44KB] to ensure that you catch and release white sturgeon with minimal harm, to help maintain this amazing fishery and to allow these gentle giants of the Fraser to live another day. Freshwater Fish Regulation [includes amendments up to B.C. Native to south and eastern parts of the United States, both the largemouth and smallmouth bass are highly regarded by anglers as spirited game fish that fight vigorously when hooked. *Don't provide personal information . The majority of white sturgeon populations in British Columbia are listed under the federal Species at Risk Act and are not open to angling. There were three principal glacial refugia that provided postglacial immigrants to BC via now extinct inter-watershed connections: the Bering Refuge (unglaciated areas of the Yukon River valley and adjacent areas of eastern Russia), the Pacific Refuge (unglaciated areas of the lower Columbia River valley and adjacent areas), and the Great Plains Refuge (unglaciated areas of the upper Missouri River east of the Continental Divide).
It is a seasonal migrant, moving upstream in the spring before returning to mainstem rivers and lakes in the fall for overwintering. Despite their longevity, populations have been impacted by loss of habitat, dam construction and water regulation on key river systems, harvest pressure on prey species, introduction of invasive species, chemical pollution from upland run-off and both targeted and indirect harvesting impacts. Typical range in length for adults: 20 to 60cm Maximum: 150cm, Typical range in weight for adults: 0.5 to 4.5kg Maximum: 25kg. In response to these pressures, westslope cutthroat trout are identified in provincial fishing regulations for catch and release through much of their range, primarily on smaller tributaries. These fish are relatively small, typically about 40 cm in length. Sterile and single gender stocking ensures that these fish do not interbred with native populations or establish home territories on their own. 8��}���U�3�lw7M��th���aj���7g��o�?��ԼY�lǮy�no���a:��v3O�q�k�������A�O-j3����mN�w�)m�;���n�Ny����j\o��n|�p��������������Z=[������*v�]^�K����;��T�雓��P��0��0�����O�)ƪ Some of the more popular sport fish species found in BC are detailed in the table below. The province continues to actively management population recovery efforts by closing Interior steelhead runs and associated spawning grounds to recreational fishing.
Due to their preference for cold, clear water with cover (undercut banks, riparian vegetation, etc., westslope cutthroat trout are often the only native species within their range. Please don’t enter any personal information. Though endangered, white sturgeon populations in the Lower and Middle Fraser River are considered healthy enough to support world class catch and release fisheries. For example, the Hadley Lake stickleback species pair has been assessed as Extinct, the Nooksack dace as Endangered, the lower Fraser River population of White Sturgeon as Threatened, and the Columbia Sculpin as Special Concern (see http://www.registrelep-sararegistry.gc.ca/species/default_e.cfm# for more information). The ocean is teeming with deadly fish, from sharks to stonefish, and you’re probably quite aware of these dangers whenever we go to the beach. Interestingly, the burbot is one of hte few fish in the province to spawn in mid-winter under the ice. Lake whitefish are primarily bottom feeders but move to shallower waters in the spring to feast on newly emerged insect larvae before returning to cooler deeper water to avoid the heat of summer. Coastal cutthroat trout demonstrate three different lifecycles. Questions about the collection of information can be directed to the Manager of Corporate Web, Government Digital Experience Division. ����P�� Mountain-building and shifting of the Rocky Mountains and the Coastal/Insular mountain ranges concentrated between 33 and 65 mya set the major pattern of river flow in BC; the predominate eastern (Peace and Liard rivers as part of the Mackenzie River system) and western-flowingÂ (all other river systems) drainages. � Interior Fraser Steelhead.

For this reason, northern pike tend to favour the cover provided by vegetated or rocky areas. At some time in the past, walleye were introduced into the Columbia River system where it appears they are now established.
