Chesapeake Bay Ecosystem Challenges

The video explores the Chesapeake Bay, the largest estuary in the U.S., highlighting its ecological and economic significance. It discusses the decline of the oyster industry due to overharvesting and disease, and the impact of nutrient pollution leading to algal blooms and dead zones. The video also covers the dynamics between menhaden and striped bass, and the challenges in balancing fisheries. It concludes with the need for ecosystem management and restoration efforts to revive the bay's biodiversity.

What is the Chesapeake Bay known for?

• Being located in only one state

• Being the smallest estuary in the United States

• Having no recreational opportunities

• Having a vast watershed covering 64,000 square miles

What was the primary reason for the decline in oyster populations in the Chesapeake Bay?

• Increased tourism

• Climate change

• Overfishing and disease

• Introduction of new fish species

How do algal blooms affect the Chesapeake Bay ecosystem?

• They provide food for all marine life

• They have no significant impact

• They block sunlight and create dead zones

• They increase oxygen levels in the water

What happens to blue crabs during late summer algal blooms?

• They become predators of oysters

• They migrate to other bays

• They swarm into shallow waters in search of oxygen

• They thrive and reproduce more

What role do menhaden play in the Chesapeake Bay ecosystem?

• They are top predators

• They graze on plankton and are a key forage species

• They are primarily scavengers

• They do not interact with other species

What led to the decline of striped bass populations in the 1970s?

• Overharvesting

• Climate change

• Introduction of invasive species

• Pollution

What was the result of the 1985 moratorium on striped bass fishing?

• Increase in pollution levels

• No change in striped bass populations

• Recovery of striped bass populations

• Further decline in striped bass populations

What is the purpose of the fisheries ecosystem model of the Chesapeake Bay?

• To monitor water temperature

• To introduce new fish species

• To increase tourism

• To evaluate if fishing leaves enough food for marine life

Which marine animals have been drastically reduced or eliminated from the Chesapeake Bay?

• Sharks and rays

• River otters and sea turtles

• Gray whales, dolphins, and manatees

• All of the above

What is needed to make the restoration of the Chesapeake Bay a reality?

• More recreational activities

• Introduction of new fish species

• Policy changes and cooperation

• Increased tourism
