Bycatch Design
Challenge
{ Chloe, Anna, Adam
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.
