Protecting native brook trout by isolating them from brown trout
In many coldwater streams in North America, nonnative trout are replacing native trout populations through hybridization, competition, and predation. Brook trout (Salvelinus fontinalis; Figure 1) are a species native to […]
Baited video cameras and environmental DNA create better picture of fish community
Fish can be tricky to count. Many fish are sensitive to disturbances in their surrounding environment, such as from an approaching diver conducting surveys, so care must be taken to […]
Dam removals improve American eel abundance
American eels (Anguilla rostrata) are slimy fish with long, snakelike bodies found along the Atlantic coast from Greenland to Brazil. Like many species of diadromous fish (species that migrate between […]
Fish communities in submerged aquatic vegetation
Submerged aquatic vegetation (SAV) are underwater plants that grow in shallow water and do not emerge above the surface. These areas are important nurseries for juvenile fish and provide refuge […]
Brown trout use restored stream habitat during winter
Due to degraded habitat and poor water quality throughout North America, stream restoration projects are becoming increasingly widespread. These projects frequently focus on restoring riparian and stream habitat, stabilizing streambanks […]
Winter flounder spawning offshore in the southern Gulf of Maine
Winter flounder (Pseudopleuronectes americanus) are small-mouthed flatfish native to the east coast of North America, ranging from Labrador to Georgia. They are right-eyed flounder, meaning that as adults, both eyes […]
Comparing habitat preference of aquatic life between beaches and riprap in Delaware Bay
Due to sea level rise and increased development in coastal areas, shoreline armoring has become an increasingly popular strategy to protect coastal communities and infrastructure. These armoring structures include seawalls, […]
What do groundwater seeps and brown trout have in common?
Imagine diving into a cool body of water after exercising or working in hot weather. This is an example of behavioral thermoregulation—changing your actions in order to influence your body […]
Using imaging sonar to count migrating river herring
Alewives (Alosa pseudoharengus) and blueback herring (Alosa aestivalis), collectively known as river herring, are small, silvery fish native to the east coast of North America. They are anadromous, meaning they […]

Forestry and fish habitat linked by restoration of large woody debris in streams
Photographs by Eiko Jones Forestry and fish habitat are interconnected across landscapes in perpetual and compelling design. Few elements of stream habitat portray this link between forest and aquatic resources […]
Where the river meets the ocean
Even though almost every estuary is unique, they all provide important habitat for a wide range of organisms and often support highly productive ecosystems. Estuaries are the link between the […]
Contemporary flame retardants replace yesterday’s – but continue to bioaccumulate in Great Lakes fish
Flame retardant chemicals have been known to wind up in places they don’t belong; in the atmosphere, in lake sediments, and in the tissues of fish and other wildlife. For […]
