Salmonid fish

Salmonid fish are a family of freshwater and saltwater fish that includes salmon, trout, brown trout, and grayling. They are known for their adaptability to various habitats and their complex life cycles, often migrating between rivers and oceans. Salmonids are characterized by streamlined bodies, a keen sense of smell, and a spawning behavior where adults return to their birthplaces to reproduce. They are important both ecologically, supporting diverse aquatic ecosystems, and economically, as they are popular for commercial and recreational fishing, valued for their flavorful flesh and nutritional benefits.
