1. Narrated by your classmates

2. Emptying the Oceans Describe why the old cliché that “there are always more fish in the sea is misleading” Define the terms: cliché, biological resources, unprecedented, exploited, intensively, depleting Compare “fully exploited” and “over-exploited”. Which term is worse? If current trends continue, what year will the populations of fish collapse & the oceans no longer be “fishable”? Group 3

3. Grub Club tomorrow (Thurs) after school starts at 3:15p promptly! (no lates) * Service Learning Hours * Learn STUFF * Learn to cook with FRESH, HEALTHY, tasty food!

4. Essential Question: What benefits do you derive from the oceans? How does your behavior (in Chicago) affect the oceans? Give 5 specific examples. Objective: SWBAT assess impacts from Marine Pollution.

5. Reasons for severe declines in fish populations: 1. People overfish (describe) 2. Fishing has industrialized (explain method & target catch) for “factory fishing” 1. Driftnets 2. Longline fishing 3. Trawling vs bottom trawling 3. Modern fishing fleets deplete marine life rapidly 1. Identify the top three “guilty” countries 2. Which species of fish has suffered the greatest decline, especially off the Northeast Coast of America? Define: “factory fishing”, bycatch Group 3

6. Several Factors Mask Declines Explain: Marine biodiversity loss erodes ecosystem services.” Using the five statements below, explain: “Although industrialized fishing has depleted fish stocks in region after region, the overall global catch has remained roughly stable for two decades.” 1. Fishing fleets now travel longer distances to reach less-fished areas of the ocean 2. Fishing occurs in deeper waters 3. More time is spent fishing & more nets and lines are set to increase catch yield 4. More powerful technology (describe these: sonar mapping, satellite navigation, and thermal sensing systems) 5. We are fishing “down the food chain” – explain this using the terms “younger”, “smaller and less desirable”, and “image make-overs.... Slimehead & Toothfish” Group 4

7. Marine Conservation Define “marine conservation”, “maximum sustainable yield”, Fisheries management has been based on maximum sustainable yield Knowledge is used for timing of harvests, scale of harvests, techniques used to catch fish Considering the impacts of fishing practices on habitat quality, species interactions, and other factors which could pose a detriment to population recovery MPAs… Marine Protected Areas (100’s along the coastlines) Why does the book imply that these areas do not do much to protect the future of ocean organisms? (list 4 reasons) Marine Reserves… compare to an MPA How do most commercial and recreational fishermen feel about the marine reserves and why? Group 5

8. Marine Reserves CLEARLY translate these statistics: Increased densities by 91% Increased biomass by 192% Increased average size of organisms by 31% Increased species diversity by 23% Benefits Produce rapid & long-term increases in abundance, diversity, productivity of marine organisms Decrease mortality & habitat destruction Lessen the likelihood of species expiration Outside the reserve… “spillover effect” – describe that, “seed the seas” – describe that Group 5
