Coral Reef 2 GIZMO

The overall goals of this activity was.....

• to observe the effects of overfishing and determine how much fishing the reef can withstand.

• to observe the effects of climate change and determine how the the reef changes.

• to observe the effects of predictor and prey dynamics.

What does the Stoplight parrotfish eat?

• Algae

• Sponges

• Parrotfish, angelfish, and snappers

• Young fish, shrimp, crabs and worms

What does the Queen angelfish eat?

• Algae

• Sponges

• Parrotfish, angelfish, and snappers

• Young fish, shrimp, crabs and worms

What does the Yellowtail snapper eat?

• Algae

• Sponges

• Parrotfish, angelfish, and snappers

• Young fish, shrimp, crabs and worms

What does the Nassau grouper eat?

• Algae

• Sponges

• Parrotfish, angelfish, and snappers

• Young fish, shrimp, crabs and worms

Based on the fact that the Nassau grouper eats Parrotfish, angelfish, and snappers. If the Grouper population on the reef increases one would expect which of the following

• The Parrotfish population to decrease but the Anglefish and Snapper Population to increase.

• The Parrotfish population to increase but the Anglefish and Snapper Population to decrease.

• The Parrotfish Anglefish Snapper populations to decrease.

Which of the following would be an observation of 80% Net fishing level.

• Parrotfish, groupers, and sea turtles all nearly go extinct. Sea

  urchins increased. Snappers, angelfish, and sponge populations fluctuated over time.

• Parrotfish, groupers, and sea turtles went extinct. Snappers and

  angelfish nearly went extinct.Staghorn and star corals declined as sponges and algae increased.

• Parrotfish, groupers, and sea turtles decreased. Sea urchins

  increased. Snappers, angelfish, and sponge populations fluctuated over time.

T/F - Net fishing kills all fish approximately equally. It also can damage delicate corals.

• True

• False

Which amount of net fishing does the GIZMO show is sustainable?

• 10%

• 20%

• 40%

• 80%

T/F - Corals are susceptible to many diseases, including black band disease and white band disease.

• True

• False
