What is a Salmon Fish?
A massive silver-coloured fish called salmon fish that can survive in both freshwater and saltwater. Which we can consume as food. Salmon is a fish of the Salmonidae family. Pacific Oceans and North Atlantic are native to salmon fish. Also, salmon are species of anadromous. Which means they dwell in the freshwater then they will go to the ocean. After that, they again come back to freshwater when it is time to spawn. The word salmon comes from the Latin term Salmo. The meaning of the word is to leap.
Including the tail, the fish has eight fins. Some fins are arranged in pairs on each part of the salmon body. On the belly of the fish are placed pelvic or ventral pins and the lower portion of the shoulder is placed pectoral pins. Through the grill, they inhale or exhale air. Also, Atlantic salmon have potential muscles and are renowned for power and speed. Regardless, the salmon fish is anadromous species which can dwell in freshwater and saltwater.

- Coho Salmon.
How do Salmon live in Freshwater and Saltwater?
A non-anadromous fish can’t move between freshwater to saltwater. They would die for change. However, salmon can exist in both places. Because they can reduce and absorb sodium into their bodies.
When salmon fish in freshwater, they increase the body’s sodium intake using molecular pumps. Again when they go to saltwater they remove sodium from their body to balance their sodium level. Salmon’s process is called osmoregulation.
After that when the fish again reverse to freshwater, they again start taking sodium. This is how the process continues. This is basically why the fish can live in both freshwater and saltwater.
