Salmon have a much grander history than what is presently shown today. The salmon that once dominated the Pacific Ocean are now just a fraction in population and size. The Pacific salmon population is now less than 1–3% of what it was when Lewis and Clark arrived at the region. [126]
Native Atlantic salmon populations outside of North America are found in much of coastal Europe, as well as Greenland, Iceland, the Faroe Islands, and the northwestern part of Russia. [23] Introduced populations of Atlantic salmon, both the common anadromous life cycle and the less common land-locked life cycle, are found in many locations ...
Atlantic salmon populations were significantly reduced in the United States following European settlement. The fur trade, timber harvesting, dams and mills and agriculture degraded freshwater habitats and lowered the carrying capacity of most North American streams. Beaver populations were trapped to near-extinction by 1800, and log drives and ...
Throughout the region, many wild salmon stocks (a group of interbreeding individuals that is roughly equivalent to a "population") have declined and some have disappeared. The status of salmon along the west coast of North America is not uniform. Some wild salmon and habitat restoration possibilities are better than others.
Late 19th century: Salmon hatcheries are used in Europe, North America, and Japan to enhance wild populations. 1961: Hatchery raised Atlantic salmon fry were released in the rivers of the Falkland Islands in a failed attempt to establish a population in the South Atlantic.
The next most important fishery by value is American lobster and Atlantic sea scallop. The Port of New Bedford, Massachusetts is America's #1 Fishing Port with fish landings valued at $369 million. Each year, there are nearly 50 million pounds of sea scallops landed there. [12] The striped bass was driven to low levels early in the 1980s. Catch ...
Some of the salmon populations are at less than 1% of their historic numbers. 15 of the 37 Chinook populations have disappeared and their steep decline is strongly correlated with the deterioration of Puget Sound as a whole. [24] In 1999, the Endangered Species Act (ESA) listed the Chinook salmon, summer chum and bull trout in the Puget Sound.
The salmon harvest in Alaska is the largest in North America and represents about 80% of the total wild-caught catch, with harvests from Canada and the Pacific Northwest representing the remainder [1] In 2017 over 200 million salmon were caught in Alaskan waters by commercial fishers, representing $750 million in exvessel value.
