Alewife spawning strategies may differ between river systems
Alewives (Alosa pseudoharengus) are small, silvery forage fish in the family Clupeidae (Figure 1). Their native range spans the eastern seaboard of North America from South Carolina to Newfoundland. Historically, […]
Effects of dam removals on riverine fish assemblages
In many rivers throughout the world, dams have greatly altered the aquatic ecosystem. These structures block migratory routes for anadromous species that live in saltwater and migrate into freshwater to […]
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 […]
Improving our understanding of stream fish habitat by including lakes in modelling
Fisheries scientists often rely upon models to assess various aspects of fish populations, such as fish habitat in streams. An understanding of fish habitat quality is vital in determining the […]
