3. Activity 15: Changes Due to Population Growth Get Started  Have you eaten fish or some other kind of seafood in the last week?  Where do you think that fish or other seafood came from?

4. Activity 15: Changes Due to Population Growth Get Started  Do you think we could have fish farms to grow fish instead of catching wild fish?  Would this help to prevent overfishing?  Do you think fish farming will be helpful, negative, or mixed?

5. Activity 15: Changes Due to Population Growth Introduction  Aquaculture is the growing of fish and other aquatic species for human consumption. Read the introduction.

6. Activity 15: Changes Due to Population Growth  How can the environmental harm from salmon farming be minimized? Challenge

7. Activity 15: Changes Due to Population Growth Procedure  If at any point in the investigation you roll a 5 or 6 and your farmed population is not 1,400 or greater, roll again until you get a 1, 2, 3, or 4.

8. Activity 15: Changes Due to Population Growth Follow Up  What kind of events affected your systems?  How did the events affect the wild and farmed populations?

9. Activity 15: Changes Due to Population Growth Follow Up  What are the benefits and trade-offs of the fish farm shown in the video?  How does this compare to the salmon farm in the activity?

10. Activity 15: Changes Due to Population Growth Follow Up  Do you think the results of fish farming will be helpful, negative, or mixed?

11. Activity 15: Changes Due to Population Growth Follow Up  What are the benefits and trade-offs involved with aquaculture? Discuss at least two aquaculture systems. Analysis 4
