A collaborative effort to balance fisheries restoration and hydropower production, the project included the removal of two dams that had blocked fish migrations for more than a century, and the construction of a river-like bypass around a third major dam that fish now use to access areas of habitat that are critical for their reproduction and recovery.

Water pollution is widely reported as one of the main causes of the decline in stocks of Atlantic salmon. In southern Norway, acidified rivers have been mitigated with lime to help improve water quality and restore fish populations.

This direct local action is coupled with European nations making agreements to reduce atmospheric emissions of acidifying compounds. In Norway, a total of 23 acidified rivers that were virtually without salmon have been successfully restored through the National liming Programme.

Between them, they now support fisheries with a catch in recent years of between 13, and 19, salmon. Recolonisation of salmon has taken place in a number of these rivers. Progress in implementing these Resolutions, Agreements and Guidelines is assessed through the review of Implementation Plans and Annual Progress Reports.

Salmon fisheries and management must adapt to shifts in the amount and distribution of fish, and must consider changes to the environment that impact salmon survival when creating management plans. Modifications to coastal and inland habitats have altered the essential spawning, rearing, and migration environments and connections for salmon between freshwater and the ocean environments.

This results in the need for habitat protection and restoration. Salmon and steelhead can also be vulnerable to climate change because they need cold water to spawn and grow in their aquatic environments.

Pacific salmon and the management of Pacific salmon fisheries can also affect Southern Resident killer whales. Listed under the Endangered Species Act ESA , Southern Resident killer whales mainly consume Chinook salmon. If the whales have difficulty in finding enough prey, this could result in a decline in their health, reproduction, and survival.

Amendment 21 improves Chinook availability as prey for Southern Resident killer whales from ocean fisheries by limiting commercial and recreational fishing off the West Coast of the United States when Chinook salmon abundance is too low.

The amendment is an example of managing salmon fisheries while considering species interactions and predator-prey relationships. The best available science about Southern Resident killer whales and their prey, Chinook salmon, was considered in the development of Amendment The following actions and locations are included in Amendment 21 and would be implemented if Chinook salmon numbers fall below a specified level of low abundance:.

The restoration of habitat is essential for the recovery of salmon and steelhead populations across the West Coast. Habitat restoration is one approach used to rebuild damaged habitat and to protect a functioning environment. Habitat restoration is completed in a variety of locations including coastal wetlands, streams, and shoreline habitats which are valuable to juvenile salmon.

NOAA Fisheries is committed to the restoration and protection of habitat for salmon species. Benefits to salmon from habitat restoration include providing ecosystems and habitats which help improve nutrient flow and freshwater productivity.

Additional benefits from habitat restoration consist of support as important nursery areas to rear, and as migration corridors to help salmon on their way to the ocean. Healthy habitat is critical for sustaining healthy salmon populations and the tribal, commercial, and recreational fisheries which rely on them.

NOAA Fisheries supports salmon habitat restoration projects through the NOAA Restoration Center and Pacific Coastal Salmon Recovery Fund. The Center and Fund work towards the restoration of nearshore habitats and estuaries which are essential to salmon. Restoration projects these organizations take on include the removal of levees and shoreline armoring, and the restoration of tidal channels.

The Community-based Restoration Program is one example where NOAA Fisheries and other partners have helped create and meet habitat restoration goals in estuary areas. Areas in the Restoration Program include Fisher Slough, Wiley Slough, and Fir Island Farm along the Skagit River.

The Skagit River estuary provides important habitat for Chinook salmon. Much habitat restoration work has been completed in the Skagit River estuary which contributes to Chinook salmon recovery, yet continued effort is necessary to achieve population recovery goals.

Nearshore habitats are extremely important to the Pacific salmon and steelhead life cycle. Juvenile salmon use nearshore habitats when they are young as a safe space to grow and hide from predators. Examples of nearshore environments include beaches, bluffs, inlets, river deltas, and estuaries.

Few animals have been as proetction to Wild salmon ecosystem protection Protectlon human experience as salmon. Their annual ecoxystem are anti-viral drugs miracle Wild salmon ecosystem protection ecosyystem. They feed us and their presence tells us that our rivers are still healthy. From grizzly bears to orca whales, at least different species depend on the marine-rich nutrients that wild salmon provide see our interactive illustration to explore just a few. The last intact salmon watersheds around the North Pacific are composed of free-flowing rivers and dense forests, which provide clean drinking water and absorb carbon to slow climate change. Millions of people around the Pacific rely on salmon as a healthy and reliable source of protein.

Preservation Wild salmon ecosystem protection pristine salmon rivers has thus been advocated Rpotection a cost-effective way of sustaining wild Pacific salmon populations. We proetction the value of freshwater salomn protection in conserving salmon and fostering resilience in the Kitlope watershed in northern coastal British Columbia—a large km 2 and undeveloped temperate rainforest ecosystem with legislated protected status. In comparison with other pristine Pacific Rim salmon rivers we studied, the Kitlope is characterized by abundant and complex habitats for salmon that should contribute to high resilience. However, biological productivity in this system is constrained by naturally cold, light limited, ultra-oligotrophic growing conditions; and the mean ± SD density of river-rearing salmonids is currently low 0. Existing data and traditional ecological knowledge suggest that current returns of adult salmon to the Kitlope, particularly sockeye, are declining or depressed relative to historic levels.
