The complex network of tributaries and lal<es that comprise the Fraser River basin supports hundreds of gcneticaUy unique salmon stocks and produces 60 per cent of the salmon caught in the province. The Fraser system is also home to 41 species ofnon-salmonjd fish and another 46 species in the estuary. All fish of th.is great river system, as well as the Fraser River itself, play a vital role in the social ;u1d cultural tapestry of British Columbia. The health of Fraser Basin streams and fish is impacted by adjacent land uses. Urban and industrial expansion, forestiy and agriculnu-al activities all generate potential tlu·eats to fish habitat. In mountrunous areas of tl1e basin, extensive forest harvesting occurs, which, if done without proper safeguards, can damage fish-bearing streams.

Protecting a river's future Protecting and improving the fishe1y resomce has been a major goal ofFisheries and Oceans Canada (DFO) tlu·ough tl1e Fraser River Action Plan (FRAP), a multi-faceted, six-year federal program started in 1991. Through FRAP, DFO and its partner Environment Canada (DOE) have been striving to improve Worlli11g to iniprove a watershed's health. the long-term enviJ·onmental health of the Fraser Basin. This report and accompanying posters summarize knowledge of the Fraser River's fish, habitat and water quality - including ongoing problems and concerns - tl1at DFO has gained during the past six years of FRAP. Highlighted tlu·oughout are actions FRAP has taken, and actions eve1yone can take, to improve tl1e healili oftl1e Fraser and its fish. (1\!fore details about FRAP's many p1·ojects can be found in the p1'ogram 's final report, Legacy for tl1e Fraser.) What ~sh need to survive Fish: barometers of river health Salmon and trout living in tl1e Fraser River system may be considered tl1c proverbial "canaries in the coal mine." The healtl1 of ilicse fish stocks - botl1 in terms of population size and stock diversity - is a reliable indicator of tl1e healtl1 of tl1e Fraser River ecosystem and the environment as a whole. These salmon ids are extremely sensitive to habitat degradation. The six species ofsalmo n tl1at inbabit ilie Fraser system - chum, sockeye, pink, coho, chinook and steelhead - as well as cuttlu·oat trout are all anadJ·omous fish. This means tl1at tbey spend part of their lives in tl1e ocean and return to freshwater to spawn. They are highly susceptible to disruptions in habitat during the freshwater phases of ilieir life cycle, when they live in streams and lakes. During tl1ese phases tl1ey require the foUowing basics: • clean gravel for spawning and incubating eggs; • adequate food supply; • a steady flow of clean, cool water well-enriched with oxygen; and • protected areas adjacent to main channels for shelter from floods and high water flow. 4 Sustllh1C1bility th 1 ·0~1gh 1•espo11sibility Unless precautions are taken to reduce their impacts, any number of human activities such as urban development, fanning and ranching, forestry activities, manufacturing, transportation, dams and mining can disrupt fish and their habitat. If habitat is protected for fish of the Fraser River, habitat for other flora and fauna - not to mention the river itself- will be preserved as well, benefitting the entire ecosystem, including people. a ood water quality Fish such as salmon and trout need cool, clean water for every stage of their life cycle. All streams naturally carry silt and other sediments suspended in the water, but too much silt can cover up gravel beds, reducing spawning habitat. If silt blankets incubating salmon eggs, they will die from lack of m.·ygen. Increased sedimentation also reduces critical fish food supplies by decreasing light needed for energy by algae and micro organisms - the foundation of the aquatic food chain. Furthermore, it smothers tiny organisms fish feed on, and, by reducing visibility in the water, mal<es it harder for fish to catch prey. Cool, clean water is needed in e11e1"y stage of a salmon's life. Too much silt can also damage fish gills. The water must also be free of high levels of metals and organic contaminants, found in stormwater runoft~ sewage and industrial effluent.
