Why Do Salmon Live In Saltwater

Salmon- large popular game fish, liked for their pink flesh, live in sea but come to freshwater to spawn.

Salmon have a truly incredible life cycle. Like all fish, salmon spawn from female eggs and then go on to develop into “alevin,” which is a term for newly hatched fish. First off, they derive nourishment from the yolk sac from where the salmon are born. Once the sac has been absorbed, the “fry,” or baby fish, then emerges from the river gravel and starts the search for food. Fry instinctively deal with the river currents and learn to swim together as a school right away. Anywhere from a couple days to two years old, fry will continue to live in fresh water until they start the next, “smolting,” phase. Smolting is a

Another popular attraction near downtown is the Issaquah Salmon Hatchery. As the most popular of the state's hatcheries, thousands of visitors come every year to watch the salmon migrate from the Issaquah Creek to Puget Sound. When the fish return to their birth waters to spawn each October, the city honors the occasion with the Issaquah Salmon Days festival. This two-day event features sporting events, live music and

A massive threat to Alaskan salmon is the pebble mine. At the beginning of the Nushagak and Kvichak rivers in the Bristol bay area, lies the biggest salmon community in the world. If the p mine was built, it would be the 2nd largest open pit for gold/copper/molybdenum in the world.

Steelhead fishing in the Pacific Northwest is the most sought-after fish in the entire Northwest and there's no guessing why. This anadromous rainbow trout is one of the hardest fighting fish around, and also one of the most challenging to catch. There's a reason for the old Northwest Anglers saying “10% of the Steelheaders catch 90% of the fish”. These acrobatic fish represent the pinnacle of many of a fisherman's time on Northwest waters. Weather it’s the hatchery run, summer run, or the winter run in the pacific northwest the

In the article “Changes at Snake River dams helping Idaho sockeye salmon” it states that “an unusual combination of low water and an extended heat wave pushed water temperatures past 70 degrees, lethal for cold-water sockeye.” I have a very strong connection to fishing and I hate it when fish die for no good reason or because of a manmade structure. A report by the National Oceanic and Atmospheric Administration said “One of the factors contributing to the deaths of sockeye salmon was “fallback,” a tendency of fish to successfully climb a dam’s fish ladder but then, running into warm water, decide to go back downstream, often via a dam’s spillway or through the turbines.” This reminds me of the time I was fishing near a small dam and caught

One of the many problems the severe water drought has caused has affected many of the animals such as the American river fish, salmon, and steelheads. In the Sacramento Bee the article “Drought Threatens American River Fish” by Matt Weiser explains how the steelhead are threatened species who are about to hatch in the American River, but due to the drought the sunny temperature and the

When rainbow trout breed the female digs a deep red which is a nest by laying on her side and flapping her tail to loosen up gravel, then she releases eggs which mix with the male’s milt (sperm) and both go into the red. Then the female fills the nest in. After the alevins (larvae) hatch they stay in the nest and absorb the sac that they were in, they now look like tadpoles but in two months they become fry which are young fish and leave the nest to feed. Rainbow trout breed around the age of two. Females can produce a maximum of 2000 eggs for every kilogram of body

Introduction: The Bull trout (Salvelinus confluentus) in the family Salmonidae and are a char native to Washington, Oregon, Idaho, Nevada, Montana and western Canada. Compared to other salmonids, bull trout have more specific habitat requirements that appear to influence their distribution and abundance (USFWS, 2015). Bull trout were historically regarded as pests due to their voracious predatory behavior. It was thought that bull trout depleted populations of “more desirable” game fish by feeding on them when they were very small thus supposedly depleting the numbers. In fact at one point there was a bounty placed on bull trout tails in Canada to encourage fisherman to rid the waters of this “Bully,” which effectively eliminated them from certain watersheds (Donald, D. B., and D. J. Alger. 1993). At one time in the early 1900’s the Bull Trout thrived in the waterways of the Northwest. The Upper Snake Recovery Unit for the Bull trout occurs within central Idaho, northern Nevada, and eastern Oregon. Major drainages include: the Salmon River, Malheur River,

In the North Pacific there are five species of salmon. Each kind of salmon is known by different names like, Chinook (king), sockeye (red), coho (silver), chum (dog), and pink (humpback). These are all valuable, but the Chinook or King Salmon were the prize of the Columbia River system. In the late 1800s about 2,500,000 cans of salmon nearly filled a cannery store and storage rooms in Astoria, Oregon. Fresh, salted, dried, and smoked were the only options for preserving and eating salmon before the spread of canning technology in the mid 1800s.

For the Most part trout are fresh water fish, but even some of the ocean species return to fresh water to reproduce. As they are from the Salmon family you can see what is meant by that. Even our commonly associated fresh water trout such as Brown, Brook, Bull, Cut Throat and Char have taken to the oceans and thrive very well there.

The Salmon River is located in Oswego County New York and it empties into Lake Ontario at Port Ontario. It is a major hub of public recreational fishing in New York State and contains a variety of fish including Chinook, Coho, and Atlantic Salmon as well as Brown Trout and many others. The Salmon River was an extremely productive tributary into the late 19th century. Unfortunately, a variety of factors led to the degradation of the water and subsequently the Atlantic Salmon population collapsed. These factors included deforestation, over-fishing, and dam construction. (dec.ny)

An epic and timeless battle plays out in annually in our beautiful province. From late summer until early winter salmon valiantly fight their way back from the ocean to their home rivers where they first hatched. This is the stuff of legends and folklore! It is difficult to articulate the impact a single fish has had on the people of BC, but suffice it to say the salmon run is unquestionably a marvel of nature.

Salmon farming is becoming more and more popular as salmon population increases. Currently, over half the salmon sold globally is farm-raised in Northern Europe, Chile, Canada, and the United States, and the annual global production of farmed salmon has risen from 24,000 to over 1 million metric tons during the past two decades (Hites, pg. 226). Because salmon farms are so widespread, salmon from farms in northern Europe, North America, and Chile are now available widely year-round at relatively low prices (Hites, pg. 226). The problems that occur from salmon farming, mostly come from how they are contained. Most salmon farm use open net-cages in the ocean which helps the salmon move around freely. Complications arise with these types of containments

Nonetheless, wild pacific salmon are fished near the shore or the ocean between May and September because they spawn in their river habitats during these months. The other challenge was that wild pacific salmon were depleting and protecting them was a great challenge as it was indirectly posing a threat to Walmart and its sea food supply chain.
