name: ____ period: ____ read section 9.1 fisheries pages 605 - 610 in the marine science textbook 1. compare and contrast finfish to shellfish. complete the venn diagram. 2. besides food, what else do marine fisheries provide humans? 3. look at the
ipple effect\ on p.608. how can people know what fish are sustainably harvested and a better choice to eat? 4. list the ways that fish can be sold. 5. give at least two reasons why the consumption of seafood has increased. 6. using figure 19.3, name the country with the highest catch and the lowest? 7. why do chile and peru have such irregular catches?

Explanation:

1. Finfish vs Shellfish: Finfish are vertebrates with fins and internal skeletons, like salmon. Shellfish are invertebrates with shells, like clams. Commonalities include being seafood. In the Venn - diagram, unique features of finfish (e.g., swim bladders) go in the finfish - only part, unique features of shellfish (e.g., hard outer shells) in the shellfish - only part, and shared features (e.g., used as food) in the overlap.
2. Marine fisheries benefits: Besides food, they provide jobs in fishing, processing, and related industries. Also, fish oil is used in supplements, and fish skins can be used in leather products.
3. Sustainable fish: People can look for certifications like the Marine Stewardship Council (MSC) label. It indicates that the fish has been caught sustainably. Also, consult seafood guides from conservation organizations.
4. Ways to sell fish: Fresh (whole or filleted), frozen, canned, and smoked.
5. Seafood consumption increase: Health - consciousness as seafood is high in protein and healthy fats. Also, globalization and better transportation make it more accessible.
6. Highest and lowest catch countries: Without seeing figure 19.3, can't answer precisely. But generally, countries like China are major fish - catching nations, and some small island or land - locked countries may have low catches.
7. Chile and Peru catches: Their catches are irregular due to El - Niño and La - Niña events which affect ocean temperatures and currents, altering fish migration patterns and abundance.

Answer:

1. Finfish: Vertebrates with fins and internal skeletons, may have swim bladders. Shellfish: Invertebrates with hard outer shells. Overlap: Used as seafood.
2. Jobs, fish oil for supplements, fish skins for leather.
3. Look for MSC label, consult seafood guides.
4. Fresh, frozen, canned, smoked.
5. Health - consciousness, globalization and better transportation.
6. Can't answer without figure 19.3.
7. El - Niño and La - Niña events affecting ocean conditions.
