There are seven species of Pacific salmon, such as chinook and sockeye. Globally, over 9,000 salmon populations exist. In 2016, an estimated 3.38 million salmon remained. From 2005 to 2015, average yearly counts showed about 721 million salmon in North American waters, indicating a declining trend in salmon numbers.
Statistics indicate that millions of salmon migrate annually for spawning. In the Pacific Ocean, Chinook salmon populations can range around 1.2 million individuals per year, while Coho populations hover around 1 million. The Atlantic salmon, primarily found in the North Atlantic, show a declining trend due to overfishing and habitat loss.
In total, the global salmon population fluctuates due to environmental factors and human activity. Effective management and conservation efforts are crucial for maintaining healthy salmon populations.
Understanding the diverse species and their statistics provides a foundation for exploring the ecological significance of salmon as well as the challenges they face in the wild. Next, we will examine the critical role of salmon in their ecosystems and the impact of climate change on their survival.
