In the Unit III Lesson, you learned about the overfishing and decline of the Atlantic Cod off the coast of Nova Scotia. Other populations of fish around the world have been affected in much the same way. This activity will help you explore which species are imperiled by current fishing practices and which are, for now, a relatively sustainable choice for the table. Materials For this assignment, you will need a computer with Internet access. Part I Visit the  Monterey Bay Aquarium Seafood Watch webpage . Click “Seafood Basics” and from the dropdown menu, click “The State of Seafood” and read the page to learn about the fundamentals of the current environmental issues related to seafood. Next, click “Seafood Basics” again and click “How can seafood be more sustainable?” Read each of the following tabs: Avoid Overfishing, Illegal Fishing, Limit Bycatch (including videos), Preserve Habitats and Strong Management. Part II Go back to the  Monterey Bay Aquarium Seafood Watch webpage . Next, click the “Seafood Basics” link, then the “What is Sustainable Seafood” and “Where Does Seafood Come from” links to answer the questions for Part II of this activity. Part III Visit the  Fishing & Farming Methods section of the webpage . Watch the videos and/or read the captions to learn about the different ways in which seafood is harvested. For some methods, there will be a video; for others, there will just be an image and a caption. Part IV Go back to the  Monterey Bay Aquarium Seafood Watch webpage . Next, click on “Recommendations,” then “Consumer Guides.” Select the guide that best represents your area based on the descriptions of the guides. Answer the questions in Blackboard using your own words and in complete sentencesQuestion 1   Which of the following best describes the Marine Stewardship Council (MSC)? MSC is a governmental organization responsible for the monitoring of marine ecosystems. MSC is a regulating body that approves design of both fishing techniques and fishing boats. MSC is an organization that certifies seafood from sustainable fisheries. MSC is a non-profit organization that funds marine science research. Question 2   How is the ecosystem most adversely impacted by shrimp fisheries? There are fewer shrimp for dolphins to eat There is an extraordinary amount of bycatch Trawlers stir up food for sea birds Invasive shrimp species are introduced to new habitats Question 3   What does an ecosystem approach to fisheries management include? A focus on just the keystone species of an ecosystem Licensing fishermen to fish only in specific ecosystems A focus on sustaining whole ecosystems; emphasizing interactions among species in the environment Factoring in the land, the rivers and the oceans Question 4   How does most of the damage to the seafloor occur through commercial fishing? Boat propellers digging into coral reefs Heavy fishing gear that drags across the seafloor Boat anchors that drag along the seafloor Digging organisms no longer having predators to control their populations due to fishing Question 5   How are species like dolphins and marine turtles most affected by overfishing? They end up with nothing to eat. They are caught in nets as by-catch. They are hit by moving boats. They are canned and sold as delicacies. Question 6   Bycatch greatly affects all but which of the following? Marine mammals Sea turtles Krill (an important food source for whales) Sea birds Question 7   Which kind of fish are especially vulnerable to overfishing? Catfish Sardines Snapper Crabs Question 8   What steps have been taken to protect the ecosystem in Alaska to protect salmon fisheries? Limits on the number of new fishing operations, and monitoring salmon populations Allowing fishing at any time of year instead of just during the summer, and with smaller nets Gave a bonus to fisherman who sell their bycatch, and who kill fewer dolphins Licenses that allow only a specific number of Atlantic Salmon and smaller nets Question 9   What does the acronym MPA represent? Marine Protection Association Maritime Protection Area Marine Protected Area Maritime Protected Area Question 10   About how much of the worlds total fisheries production is estimated to be illegally QUESTION 1 With __________, one species may negatively affect another, but will not be affected positively or negatively. amensalism commensalism mutualism parasitism 10 points    QUESTION 2 Vultures feed largely on carrion (dead animals). Their role in the ecosystem is largely as that of a ___________. predator true predator scavenger parasite 10 points    QUESTION 3 The yucca moth interacts with the soapweed yucca in which way? The moth pollinates the flowers so the larvae can eat the seeds. The plant provides shelter for adults. The moth larvae feed on the roots of the plant. The yucca secretes chemicals that kill the moth. 10 points    QUESTION 4 Cattle egret follow herds of cattle and feed on both the insects stirred by the movement of the cattle and the biting insects that irritate the cattle. This is an example of: parasitism. predator-prey. mutualism. amensalism. 10 points    QUESTION 5 Harvesting timber in such a way that only select trees are cut and the population of those trees within the targeted forest is allowed to return to the carrying capacity is an example of ___________. give-and-take strategy yield sustainable yield over-harvesting Match the organisms to the relationship.                                                                          orchid / tree                                                                          coyote / rabbit                                                                          yucca moth / soapweed yucca                                                                          cowbird / warbler                                                                          tapeworm / human A. predator-prey B. amensalism C. brood parasitism D. parasite E. mutualism F. commensalism QUESTION 7 1.
