Fry-Fish-Plate

Bryan Silver

Kalani High School (http://www.cajuncrawfish.com) HCPS III Science Standards Addressed: B.S. 2.2, 2.5, 5.2 & 5.4

Grade Level: 9 Project Time Span: 8 months (includes 1 field trip) To The Teacher: This "Fry-Fish-Plate" project can be long or quick depending on equipment available and how much you want to be involved. This project will engage students, teaching them how they can positively influence their world around them and their own lives. It will educate them on the life cycles of fish. This project will focus on breeding and number of offspring produced; grow out rates of fish, selection of genetically desired fish, marketability of farm-raised fish, cleaning the fish and consumption of the fish the students raise. This hands-on learning experience brings the lesson to life and allows students to get their hands wet and dirty. Our ocean are on a serious decline and alternatives need to be developed. Educating the youth on raising their own fish in a back yard and making good fish choices in restaurants will go far in changing how we as a community and world utilize its resources in sustainable ways. It will also help students dispel old prejudices of as a trash fish. Goals of the Lesson: • To look at research on fish stocks in the ocean • To compile a list of good fish and bad fish to eat based on environmental impact • To learn the benefits of , and Hawai'i's contributions through fishponds • To learn how to pass your vote with a fork • To study the life cycle of fish Student Learning Objectives (Benchmarks): This lesson addresses Grade 9 benchmarks for HCPS III Science Standards: 8.5.2.2 Science Technology and Society: Risks and benefits of solutions to biotechnologies to population and available resources. • Management of limited aqua resources • The effects of genetic manipulations of food , for the wild populations and human consumption. 8.5.2.5 Malama I Ka '.Aina: Sustainability: Students make decisions needed to sustain the life we have for future generation as with limited resources. • Exploring how aquaculture technologies affect human and environment. 8.5.5.2 Biological Evolution: Explanation of natural selection and human intervention to select for genetic traits.

Property of UH Manoa - Curriculum Studies • Day 2: Discuss findings from library research. o State of fisheries on west and east coasts o Aquaculture revitalizing fish populations o Hawaiian fish ponds, benefits to the environment o Modern fish farming techniques o Maintenance of a fish tank

• Day 3-4: Watch video "Farming the Seas" by habitat media + PBS Total time is 1 hr 45min of film.

• Day 5: Students to visit a working fish pond, Paepae 0 He'eia in Kaneohe o Students to take notes on how to maintain a fishpond. o Inquire with the keepers of traditional practices of Hawaiian fishponds. (construction, styles, size of pond verses fish raised) o What are the modern methods used to farm fish in the pond.

• Day 6: Set up grow out tanks and have system running before the introduction of fish. Once tanks have been running for a week supply the fry to be grown. Spread out in the smaller tanks or put together in one large tank.

• Day 7: Approximate time for the fish to grow to one pound depends on feeding and size of environment should be 6-8 months. If fish are being grown in 10 gal tanks limit to two fish per tank.

• Day 8: Do regular cleanings of tank maintaining water quality.

• Day 9: Survey the students on what they consume for and how often. Discuss with students how they can make a difference in the choices they make at restaurants in what fish are caught. ("Voting with the fork"). See appendix 1. Assessment: • Students will present on the benefits of farming fish. • Students will describe how a fishpond works both in pre-contact and modern days. • Students will report on modern techniques to raise fish. • Students will clean, cook and consume the fish they raised at the end of the year. Extension: • Students can write to NOAA expressing their views about up coming legislation dealing with our Hawaiian fishers. http://www.noaa.gov/coasts.html • Students can also write to their state congressman about the issues of fisheries management.

Tel: 541-2600 ext. 100 • Students supply their letter and response to the letter in final presentation of the project. Evaluation of Lesson: What worked well • Getting the students to clean a fish. • Having them eat what they have worked to grow. • Having them experience raising their own food to eat. Appreciating the amount of labor and time involved. • Having students reflect upon their experience with the project. Do they make better fish choices in restaurants and supermarkets?

What would I do differently • Produce my own fry for the following year's class. • Contact a DOE teacher with an aquaculture program.

Property of UH Manoa - Curriculum Studies Appendix 2: Substituting for Popular Seafood http://www.oceansalive.org/eat.cfm

Making Fish Substitutionsitute wild Alaskan salmon for farmed salmon. ( in U.S. stores and restaurants is always farmed.)

If you live in New England and want to serve cod, serve hook-caught instead of trawl-caught . If you live on the West Coast, sablefish/black cod is a good replacement.

Farmed striped bass can be used as a substitute for many species of depleted fish such as Pacific rockfish, , snappers, orange roughy and Patagonian toothfish (often called Chilean seabass).

Catfish can also be substituted for orange roughy.

For meaty warm-water fish like grouper, try mahimahi instead.

Most shrimp production outside the U.S. entails considerable habitat destruction or bycatch. If you want to serve shrimp, California trap-caught spot prawns (also excellent frozen) and northern pink shrimp from Newfoundland are the best choices.

Dredging or dragging for can damage the seafloor habitat. Replace dredged mussels, oysters and scallops with farmed shellfish raised off­ bottom on ropes or racks.

U.S. Farmed crawfish make an excellent and less expensive replacement for spiny , which are overfished in many places.

It's easy to "Vote With Our Forks" (and our pocketbooks) for . This sends a powerful message to the marketplace that we reward fisheries and aquaculture farms that operate in sustainable ways.

1. When buying seafood at the market or ordering seafood from the menu, ask WHERE does this fish come from? HOW was it caught? HOW was it farmed? If the seafood products they offer are not caught or produced by sustainable fisheries, or if this information is UNKNOWN, ask them to find out and start carrying seafood from sustainable sources.

2. NOAA Fisheries will soon begin asking for public input on projects. Let them know what you think by sending a letter to NOAA.

3. Join Seafood Choices Alliance, a free program that acts as a central clearinghouse of seafood information while working to broker partnerships between subscribers, the conservation community and other consumer groups.

6. U.S. citizens can ask their Congressional representatives what they are doing to do to implement the policies called for in the Sustainable Fisheries Act (Magnuson-Stevens Act). Citizens of all nations can urge their governments to participate in effective fisheries management. You can find out more about ratifying the U.N. Agreement on the Conservation and Management of Straddling and Highly Migratory Fish Stocks here.
