Lower Hudson and Harbor World Fish Migration Day Fish Count

Each spring the Hudson River is alive with migratory fish species that are drawn into the protective waters of the estuary as part of their spawning cycle. Estuaries provide smaller, shallower waterways with protection from the much larger fish that circulate in the ocean, along with a wonderful buffet of foods. Most of our migratory species are anadromous, meaning they live in the ocean and move into the Hudson just to reproduce. After spawning, most of the young fish spend only months in the Hudson, yet some can spend a year or several years here before moving back out to the ocean waters. We also see the migration of one catadromous species, the American eel. Catadromous fish spend most of their lives in the estuary and use the ocean as their spawning grounds. We see the young glass eels also moving into the Hudson during the late spring. Join us at one of our site locations to participate in a fish count (seine fishing, rod & reel, traps, etc.,) looking for these migratory species as they enter into the Hudson River Estuary! Multiple Locations Participating, please check out our website for more information!
