Abstract 
Diving Deeper into Salmon’s Superpowers: Magnetic Mysteries and Genetic Marvels. In a riveting exploration of the awe-inspiring world of salmon migration, we unravel the secrets behind these incredible f ish. Salmon’s extraordinary journey comes to life as we uncover how they harness Earth’s magnetic field and their keen sense of smell for navigation. They’re equipped with magnetic particles in their bodies, and their DNA may hold the key to their remarkable homing abilities. However, it’s not all smooth swimming for salmon. They face formidable challenges during upstream migration. Climate change, pollution, and man-made obstacles like dams and hydropower schemes disrupt their epic odyssey. To make things even more intriguing, artificial light pollution emerges as an unexpected antagonist. It’s not just salmon in the spotlight but the whole ecosystem. This journey is a saga of nature’s marvels and modern environmental dilemmas, urging us to protect these remarkable creatures. Join us on this exhilarating expedition as we uncover the magnetic allure and genetic wonders that make salmon migration an extraordinary tale.
