Where are the blue crabs?

Intro
  • During this past week, we have learned about the
    decreasing numbers of the blue crabs in the
    Chesapeake Bay. Throughout this presentation we
    will talk about blue crabs and over fishing.
  • Our Hypothesis IF fishermen catch too many
    crabs, THEN they are interfering with
    reproduction.
  • So be looking forward to learning more about Blue
    Crabs.

Overfishing
  • Fishermen should establish rules on fishing for
    the blue crabs. The cause and effect for over
    fishing is that when fishermen overfish on one
    season, the next season there will be less blue
    crabs.
  • If fishermen overfish on blue crabs sooner or
    later they will become extinct.

Fishing game
  • We played a fishing game that taught us about
    overfishing. When playing the game we saw that we
    were overfishing and tried to establish rules to
    control the overfishing issue.
  • Our rules were you could only catch two high
    valued fish. Turns out that our rules didnt work
    because we worried so much about the high value
    fish and ended up catching all the low valued
    fish. Since we could only catch two high valued
    fish per round and the population kept doubling
    our fish business wasnt working out.

Location of Fisheries
  • The picture in the next slide is a map of the
    Chesapeake Bay and the location of areas where
    you cant fish for crabs. In the purple is the
    space where you cant fish for blue crabs.
    Everywhere else is legal.

Conclusion
  • As we have shown in this presentation the blue
    crabs are being overfished. The crabs are in need
    of need of help. You are one of the people who
    can help solve this problem. Throughout this
    presentation we have talked about blue crabs
    being overfished. Thank you.
