Bycatch Design Challenge
Students will be introduced to the issue of bycatch in the fishing industry by learning about albatrosses getting caught on fishermen’s hooks. They will also learn about the methods that scientists and fisherman have developed to reduce albatross bycatch. Next, students will be presented with the problem of designing a net that will reduce bycatch by catching adult salmon but not catching smaller fish. They will test their design and record and analyze their data.
