Pink salmon or humpback salmon, scientific name, Oncorhynchus gorbuscha is the smallest and most abundant species in the Pacific Ocean. It is a type of Andromedus fish.

Pink Salmon Profile

After the pink salmon in the sea returned to their bursting streams of bright silverfish, the colors turned pale gray with a yellowish-white belly behind (though some turned the overall pale green color). As with all salmon, in addition to the dorsal fin, they also have an adipose fin.

The fish is characterized by white stools with black stools, no teeth in the tongue, large oval-shaped black spots on the back, a V-shaped tail, and an anal fin with 13-17 soft rays.

During their spawning migrations, the men returned in an accented hut, hence their nickname “humpies”. Pink salmon weighs an average of 1.8 pounds (2.2 kg). The maximum record size was 30 inches (76 cm) and 15 pounds (6.8 kg).

Reproduction

Pink salmon in their native range have a rigorous two-year life cycle, thus seamless and even do not interfere with the year-to-year population.

The pink salmon run in Washington State occurs during the weird years. Adult pink salmon usually return to the stream flowing from the ocean.

When hyperechoic freshwater is found, coastal flows occur from late June to mid-October and some longer rivers and spawning in intertidal areas or in the mouth of rivers.

Using her tail, the female stream beds, where she deposits her eggs, excavating a pit-shaped nest called a rad (Scandinavian term for “nest”).

As soon as he lays eggs, he is approached by one or more males, which fertilize them when they are greedy. Subsequently, the female again deposits the newly deposited zygotees with her tail’s fork against the pebble on the red top.

The female lays several thousand to two thousand eggs in red, often fertilized by different males. Women protect their reds until they die, which comes within a few days of the eruption.

In dense populations, one of the major sources of mortality for the fetus is a superposition of red color by the fish mixed with the latter.

Depending on the temperature of the water, the eggs hatch from December to February, and in March and April, the pebbles emerge from the gravel and rapidly flow down to the bottom of the river to about one-fourth of the weight.

The fish attain sexual maturity in the second year of their life. They return to freshwater in the summer or autumn as young adults.

Pink and bark salmon are sometimes bred in nature to form hybrids known as Miko salmon; The hybrids are disinfected.

Distribution and Accommodation

Pink salmon is the preferred temperature of Hamaguchi fish at 5.6 to 14.6 ° C, an optimum temperature of 10.1 ° C and a higher disadvantageous lethal temperature of 25.8 ° C.

The local range of the species is in the Pacific and Arctic coastal waters and rivers, from the Sacramento River in northern California to the Mackenzie River in Canada; And west to the Lena River in Siberia, to Korea and Japan’s Honshu.

In North America, pink salmon flowed from the Mackenzie River south of the Arctic as a tributary to Puget Sound, Washington, although they were reported on the San Lorenzo River near Santa Cruz, California, and on the Sacramento River in northern California. The 1950s.

A new record for the Salinas River at the southern extremity of the pink salmon spawning was published on the 21st.

In the autumn of 2017, a dozen pink salmon were counted on Lagunitas Creek, about 25 miles (40 kilometers) north of San Francisco, California.

Pink salmon was introduced in North America and Iran into the Great Lakes. In Europe, pink salmon were introduced in Europe from the 6th to the white sea and the Barents Sea basin in Russia.

Pink salmon

The stray fish have been caught from these rivers in Norway, Sweden, Ireland, Great Britain, and Iceland, and even in Norway, self-reliant populations have faced rising water.

In 2017 a larger number of species than usual were caught in the Scottish river and the spanning was recorded.

Preservation status

NatureServe lists pink salmon as critically involved in California and trapped in Washington. In Alaska and British Columbia, they are considered safe.

Under the Endangered Species Act, no pink salmon is listed in the evolutionarily important unit.
