15 interesting things about salmon
Did you know? After spawning, Pacific die , and sometimes their decomposed bodies continue to swim. This phenomenon is callbecause the muscle movements are still active.
Did you know? Most Pacific die shortly after spawning, but many Atlantic survive and return to the ocean to spawn again in subsequent years.
Pacific: Most of these die after spawning, once in their lives (called “semelparous”). Death after spawning is part of their biological process, a way to efficiently pass on their genes to their offspring.
Atlantic Salmon
In contrast, some Atlantic can survive and return to the ocean to regenerate and spawn multiple times in their life (called “iteroparous”).
Did you know? A female can lay up to 5,000 eggs, but only a few survive to adulthood.
The young fish face risks from other แทงบอล UFABET ราคาดีที่สุด ไม่มีขั้นต่ำ animals, lack of food, and unsuitable water conditions. The chances surviving from egg to adulthood are very low, typically as low as 1% or less. This means that out of 5,000 eggs, only a few may survive to adulthood.
Did you know that during their return journey back to the stream to spawn, known as the Run,” some do not eat at all and simply use up their energy reserves for the journey. This is because not eating during spawning is essentially a survival strategy that allows to maximize their energy efficiency and prioritize reproductive efforts in their final stages of life, often traveling hundreds of miles.
Did you know? Depending on the species, biological readiness and aquatic environment, it can take salmon two to four years or more to return to their birthplace to spawn. They have to travel thousands of miles. After spawning, female protect their eggs from predators , and sometimes both female and male may die after the spawning process, as it takes so much energy to travel back and forth to lay their eggs.
Did you know? use their sense of smell to find their way back to their spawning grounds.
They leave behind a chemical map as juveniles and use this “scent map” to navigate their way back home as adults, helping avoid getting lost and successfully completing their spawning mission.
Did you know? Salmon have an extremely good sense of smell.
Which is hundreds of thousands times more sensitive than humans. use this sense of smell to follow the scent of water flowing from their source. When are ready to spawn, they swim upstream to their birth area, lay their eggs, and then die. Therefore, this sense of smell is very important for the survival of salmon.
Did you know that salmon actually have excellent eyesight ?
They can perceive a wide range of colors, including ultraviolet (UV) radiation, which humans cannot see. This allows salmon to be excellent at detecting both predators and prey, allowing them to monitor the cleanliness of the water, avoid contaminated areas, and improve the safety of their living environment.
Did you know? Salmon are very sensitive to water temperature.
Making them one of the most sensitive species to changes in climate and water temperature. Salmon thrive and develop best in cool, oxygenated water. Excessive water temperatures can affect salmon feeding, growth, and survival.
High water temperatures from climate change, global warming, or human activities can affect salmon development and growth, as well as food availability and the ecological balance of salmon. These conditions put salmon survival at risk.
Did you know? Norway and Chile are the world’s largest producers of farmed salmon , which contribute significantly to the global salmon supply. Norway is a pionee farming , having begun developing the industry in the late 1960s. Chile is another major player in the global farming market, with a particular focus on Atlantic salmon production
Did you know? Alaska is home to all five species of Pacific , including Chinook, Sockeye, Coho, Pink, and Chum. Alaska has strict policies in place for salmon management and protection to maintain and promote long-term sustainable fisheries. It is illegal to in Alaska because of the state’s commitment to maintaining and enhancing a healthy aquatic environment where aquatic animals.
Did you know that the pink or red color seen meat.
Actually due to the salmon getting a substance called “Astaxanthin” from their diet, which is found in krill and oysters. Astaxanthin is a pigment that is pink to red and has many health benefits as it is an antioxidant that helps prevent many diseases. If does not get astaxanthin from their diet, their meat color will be gray
Did you know? The largest ever caught weighed 126 pounds (57 kilograms), a king caught in 1949 near Petersburg, Alaska, known for its rich fishing grounds
Did you know? have the ability to jump very high, allowing them to leap out of the water as high as 10 feet (3 meters) to climb waterfalls or dams during their migration. This jump helps them to return to their birthplace to lay their eggs.
Did you know? can swim at speeds of up to 9 mph (14.5 km/h) and can swim several miles in a day during their migration.
