_____ 2. Which of the following is a cause of the degradation or destruction of aquatic habitats?
a.
b.
c.
d.
e.
Rising sea levels
Shrimp farming
Coastal development
Dredging and trawler fishing operations
All of the above.
3. Match the term in Column A with its description in Column B.
Column A
Column B
____ ballast water
A. Extending a long net that is up to 80 miles long and up
to 2,400 m below the ocean surface to trap large
amounts of fish.
B. Putting out line up to 130 km long hung with numerous
baited hooks.
C. Non-target species that are caught inadvertently in the
pursuit of commercially valuable species
D. Fishing method that involves dragging a funnel-shaped
net along the ocean bottom.
E. Water that is stored in tanks in cargo ships to keep them
stable, that may inadvertently transport organisms from
one part of the world to another.
F. Occurs when it is no longer profitable to continue
fishing for a specific species.
G. A resource that is not owned or managed by any
particular person, organization, or government;
therefore, it is vulnerable to overexploitation
H. Fishing method that involves extending a large circular
net beneath a surface schooling species then drawing the
top of the net to a close to trap the species.
I. Device that shrimp trawlers are required to incorporate
into their nets that allows sea turtles to escape and avoid
drowning.
____ bycatch
_____ open-access resource
_____ commercial extinction
_____ trawler fishing
_____ purse-seine fishing
_____ drift-net fishing
_____ longlining
____ turtle excluder device (TED)
4. What do you think would be the best way to institute and enforce controls over the environmentally harmful
fish harvesting methods described on pp 254-255?

5. Mark each statement as either TRUE or FALSE.
_____ a. The majority of water pollution comes from land based sources.
_____ b. Smaller fishes are most vulnerable to overfishing, followed by the large species that prey upon them.
_____ c. Up to 30% of the fish caught worldwide and countless birds and mammals are killed unnecessarily as
bycatch.
_____ d. Marine and freshwater fish are threatened with extinction by human activities more than any other
group of species.
_____ e. Six of the world’s seven sea turtle species are threatened or endangered.
_____ f. Since 1986, all nations have observed an International Whaling Commission (IWC) moratorium on
whale hunting.
6. List FOUR reasons why aquatic biodiversity is difficult to protect.
I. ________________________________________________________________________________
II. _______________________________________________________________________________
III. _______________________________________________________________________________
IV. _______________________________________________________________________________
_____ 7. Which of the following is NOT a factor that has led to the decline in the number of Florida
Manatees?
a.
b.
c.
d.
e.
Collisions with speeding boats or propellers
Entanglement in fishing lines and nets
Degradation of underwater sea grass beds
Heated water released by industrial operations or nuclear power plants
Invasive species like water hyacinth that clog waterways impairing manatee navigation
8. Select ONE of the factors from question #7 and explain a strategy that could be used to protect the Florida
Manatee from the impact of this factor and prevent its premature extinction.
