The Maryland Fish and Wildlife Conservation Office works to restore migratory fish and other aquatic species, and their habitats in the waterways of Maryland and surrounding states. We work in the Chesapeake Bay watershed, coastal waters of Maryland and Delaware, and other freshwater streams of the mid-Atlantic.

About Us

Maryland Fish and Wildlife Conservation Office was established in 1985. We work to conserve and restore fishes and aquatic species in the Chesapeake Bay watershed and Delmarva Peninsula in Maryland and surrounding states. Our priorities are inter-jurisidictional migratory fish, aquatic invasive species invasive species
An invasive species is any plant or animal that has spread or been introduced into a new area where they are, or could, cause harm to the environment, economy, or human, animal, or plant health. Their unwelcome presence can destroy ecosystems and cost millions of dollars.

What We Do

The Maryland Fish and Wildlife Conservation works with partners to conserve and restore American Eel, American Shad, and River Herring through direct population studies and habitat restoration.  We work to control populations of invasive Northern Snakehead in the mid-Atlantic region.  Additionally, we manage Atlantic Coast tagging programs for Striped Bass, Atlantic and Shortnose Sturgeon and horseshoe crabs to ensure sustainable management of those species.

Northern Snakehead Control and Management

Across the landscape, undersized, aging and improperly placed road-stream crossings create barriers in our rivers, streams, and tidal wetlands. These structures fragment aquatic habitat and prevent or greatly reduce the ability of aquatic species to move freely to migrate, feed, and reproduce. These poorly designed structures are also more prone to clogging, causing flooding, and washing out...
