ELLSWORTH, Maine (WABI) – More than 50 people in Ellsworth Wednesday night talked about ways to keep streams, rivers, and fish safe here in Maine. <Read More>
The scientific name for the Atlantic salmon is Salmo salar. Its origins are Latin where Salmo means salmon and salar means “leaper”. Atlantic salmon are known for their ability to jump high out of the water, sometimes as high as 10 feet, and must do this to navigate the sometimes steep falls of our rivers.
Salmon are anadromous, which means they spend their juvenile lives in freshwater, migrate out into the ocean to grow to adults, and migrate back to freshwater to spawn. Upon re-entering freshwater, salmon stop eating and live off of their fat reserves they build up while feeding in the ocean.
Atlantic salmon are iteroparous, which means they can spawn more than once. Some adults will migrate back to the ocean after spawning (these fish are called kelt, or black salmon) to regain their strength and fat stores before returning for a second or even third time to spawn. Fish species that spawn only once and then die are referred to as semelparous.
