Maintaining the ‘wild and sustainable’ brand for BC steelhead fisheries remains the highest priority for this species’ management and is fundamental to its continued value and appeal.
In BC, one of the most profound effects of the Anthropocene has been the introduction of non-native fishes. In 2006, the Nechako, Upper Fraser, Upper Columbia and Kootenay populations were listed as Endangered under the Species at Risk Act. Recognizing the effects of the Anthropocene on BC’s native fish diversity, the Canadian Species at Risk Act (enacted in 2003) seeks to assess which species are at risk and to affect their recovery. In all cases, coastal cutthroat trout return to their natal stream to spawn.
Some fishes in BC (e.g., the stickleback species pairs, the Salish sucker and the Nooksack dace) and considerable intraspecific diversity (e.g., the thousands of genetically distinct salmon and trout populations) are considered to have evolved in situ since the end of the last glaciation and are, in this sense, “made in BC biodiversity”. While some yearly and regional variability in fish returns is a normal factor in managing a wild fish population, the persistently depressed state of numerous steelhead stocks warrants further examination. Residents may establish a territory in or near their natal stream and remain there for their entire lives. Within reach is some of the best freshwater fishing in North America. Other species that reproduce in salt water, but spend time feeding in fresh water are known as catadromous fishes (e.g., American eel), but BC contains no such species.
The largemouth bass is known to harbour parasites which may further endanger native species. Recognizing the effects of the Anthropocene on BC’s native fish diversity, the Canadian Species at Risk Act (enacted in 2003) seeks to assess which species are at risk and to affect their recovery. There have, however, been several important extinctions of BC’s freshwater fish biodiversity; the extinction of all of the innumerable Chinook salmon populations from vast areas of the upper Columbia River after completion of the the Grand Coulee Dam in Washington State in 1942 (David Thompson remarked on rotting carcasses on the shores of Columbia Lake!)

Fortunately the Kootenay River watershed continues to support numerous, healthy populations. 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. Webcam Links. For conservation information relating to Sturgeon, please visit the Fraser River Sturgeon Conservation Society. Black crappies prefer clear water with little current, submerged material and or weeds and muddy or sandy bottoms such as one might find in ponds and small lakes.
The signal crayfish is a solitary omnivore, eating a variety of food ranging from decomposing roots to meat, including smaller crayfish and fish.
Dolly Vardens exhibit a range of different life history strategies from those that live their entire lives in small streams to ones that migrate to larger streams or lakes on to anadromous fish that migrate to the ocean. Several salmon populations have been assessed at some level of risk as well (e.g., Okanagan Chinook salmon, Cutltus Lake sockeye salmon, Thompson River coho salmon). Taylor, E.B.
As white sturgeon mature after 17 to 20 years and can live for more than 100 years, impacts or injuries can be long lasting.
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. Freshwater Sport Fish. freshwater invertebrates (e.g. Coastal cutthroat trout (Oncorhynchus clarkii clarkii), Typical range in length for adults: 35 to 55cm Maximum: 76cm, Typical range in weight for adults: 0.9 to 2.3kg searun 11 to 91g stream-resident Maximum: 8kg. An analysis of homogenization and differentiation of Canadian freshwater fish faunas with an emphasis on British Columbia. Their sizes and lengths vary significantly depending on the life history with anadromous bull trout being hte largest. The first “record” of freshwater fishes in BC dates back to about 50 million years ago (mya) and is associated with the discovery of the fossil salmonid fish, 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). 2006. Despite their close connection, the two species do not appear to interbreed, even when they spawn in the same streams. Freshwater fishes of British Columbia Web Description: The Royal BC Museum Handbook series for herpetology and mammalogy is nearly complete, with only Marine mammals yet to be printed. The burbot has a long tapering body that reminds some of a ling cod (an unrelated saltwater fish). This fish is well distributed across the province and its population is considered secure. COSEWIC Assessment and Status Report on White Sturgeon [PDF 2.0 MB], White Sturgeon Recovery Strategy [PDF 49.1 MB], Typical range in length for adults: 20 to 35cm Maximum: 60cm, Typical range in weight for adults: 0.1 to 0.5kg Maximum: 4.5kg, Kokanee are a freshwater form of the sockeye salmon. 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. 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 …
