1. Describe the average red snapper in 1962 in terms of weight, length, and age. How about the red snapper in 1985? Today?

2. What is the connection between red snapper age and number of eggs laid?3. Why are red snappers today not reaching the age and size of red snappers in

1962?4. How does overfishing affect red snappers ability to rebuild their population?

1. What trend do you see in the cod fishery data from 1850 to 1950? If this trend had continued, would the cod fishery have collapsed in 1992?

2. How might technology, such as Global Positioning Systems (GPS) which was invented in 1973, have impacted the cod fishery?

3. Predict how the collapse of the cod fishery in 1992 may have impacted the ecosystem (HINT: what do cod eat? What eats cod?)

1. Describe how overfishing is impacting our oceans today in terms of biodiversity.2. If overfishing continues, what will happen to fisheries in the future?3. How will the 1 billion people in the world that rely on fish for their primary source of protein be

affected by overfishing?
