Oyster Ecology and Safety Issues

The video explores the vital role of Texas estuaries and bays as nurseries for marine life, focusing on seagrass beds and oyster reefs. Seagrass beds provide habitat and food for young marine species, while oyster reefs offer shelter and help clean the water. The video also highlights the importance of recycling oyster shells to maintain healthy reefs and sustain marine ecosystems.

What role do estuaries and wetlands play in the life cycle of marine species?

• They are primarily used for recreational activities.

• They serve as nurseries for young marine species.

• They are areas with no significant ecological function.

• They are breeding grounds for adult fish.

How do seagrass beds contribute to the estuarine ecosystem?

• They are primarily decorative.

• They offer food and shelter for marine life.

• They are used for human agriculture.

• They provide nesting sites for birds.

What is a significant threat to seagrass beds in Texas?

• Overfishing

• Pollution from boats

• Excessive sunlight

• Lack of nutrients

How do oyster reefs benefit the marine environment?

• They reduce the salinity of the water.

• They are used for human recreation.

• They increase water temperature.

• They provide a habitat for various marine species.

What is the purpose of oyster shell recycling?

• To create new habitats for fish

• To provide building materials

• To reduce water pollution

Why are oysters economically important?

• They are a key component of the coastal economy.

• They are primarily used for decoration.

• They are a major source of freshwater.

• They are used in traditional medicine.

How do oysters help clean the water in estuaries?

• By filtering out pollutants and sediments

• By absorbing sunlight

• By reducing water temperature

• By increasing water flow

What is a potential risk of consuming oysters from polluted areas?

• They may contain harmful pollutants.

• They may be less nutritious.

• They may be more expensive.

• They may taste bitter.

Who determines the safety of oysters for consumption in Texas?

• Texas Environmental Agency

• Texas Parks and Wildlife

• Texas Department of Health

• Texas Department of Agriculture

What happens to oysters when they filter pollutants from the water?
