Salmon use their pituitary glands to ‘see’ when it’s time to migrate One of the enduring ichthyological mysteries is how migratory fish know when it is time to move from their winter to summer habitats. The ability to tell when the seasons are changing is crucial for a wide range of major life events, including feeding and spawning, as well as migration. Many animals are sensitive to photoperiods, or the changing length of the days across seasons, but while scientists have a good understanding of how photoperiodism works in birds and mammals, how exactly fish recognize changes in day length has remained a mystery—until now.

Gulf of Maine, Explained: Anadromous Fish The alewife run is one of the Gulf of Maine’s most awe-inspiring seasonal events. Every year, our rivers pulse and shimmer from bank to bank as they fill with these small anadromous fish. Zach has a real passion for anadromous fish — especially alewives. Over the years, countless strangers have stopped to ask him about his cast-net and bucket of fish, and he’s always happy to oblige with an explanation. During these interactions, however, he’s noticed something: not many people know what the word anadromous means. In this short video, Zach quickly explains what it means to be anadromous, as well as the crucial role these fish play in the ecosystem.

Zach Whitener has a passion for #anadromous fish. But what does that even mean? He explains in our latest video:
