Chesapeake Bay's Striped Bass Population Decline

What is one key cause of the decline in Chesapeake Bay's striped bass population?

• Overfishing in the region

• Increase in fish die-offs due to insufficient oxygen levels in the water

• Pollution from oil spills

• Introduction of invasive species

How do human actions such as land development contribute to the decline of the striped bass population in Chesapeake Bay?

• By causing oil spills that contaminate the water

• By increasing the water temperature to levels unsuitable for fish

• By leading to more soil and sediment in the Bay, which diminishes sunlight and disrupts photosynthesis

• By overfishing and reducing the number of striped bass directly
