Chesapeake Bay Ecosystem Dynamics

The video discusses the role of forage fish in the Chesapeake Bay ecosystem, highlighting species like the bay anchovy and Atlantic menhaden. It explains the ChesMMAP program's efforts to monitor fish and invertebrate populations and their interactions. The video also addresses environmental concerns such as nutrient pollution and shoreline hardening, which affect habitat quality. Finally, it emphasizes the importance of managing forage fish resources to prevent over-harvesting and ensure the survival of predator species and seabirds.

What is the primary role of forage in the ecosystem?

• To provide shelter for larger fish

• To serve as food for larger organisms

• To clean the water in the bay

• To reproduce rapidly

Which two fish are highlighted as prominent forage species in Chesapeake Bay?

• Opossums and eagles

• Atlantic menhaden and bay anchovy

• Striped bass and bluefish

• Atlantic salmon and bay anchovy

What is the main objective of the ChesMMAP program?

• To monitor and assess fish and invertebrate abundances

• To clean the bay

• To increase fish population

• To build new habitats

Which organisms are considered important forage species for benthic fish?

• Snakes and frogs

• Worms, bivalves, and mysids

• Birds and mammals

• Trees and plants

What is the maximum lifespan of a bay anchovy?

• 10 years

• 5 years

• 1 year

• 2 or 3 years

What environmental concern is associated with Chesapeake Bay?
