Salmon are important food fish and are intensively farmed in many parts of the world, with Norway being the world’s largest producer of farmed salmon, followed by Chile.[5] They are also highly prized game fish for recreational fishing, by both freshwater and saltwater anglers. Many species of salmon have since been introduced and naturalized into non-native environments such as the Great Lakes of North AmericaPatagonia in South America and South Island of New Zealand.[6]
