6) What percentage of fish in the waters around Great Britain will have disappeared within 20 years without quick and intense protection? a) 20% b) 50% c) 70% d) 90% 7) Overall, the most damaging and reckless fishing technique employed by some fishermen today is: a) purse-seine nets b) bottom trawling c) long-lining d) zebco, bobber, worm 8) The fall in fish species found in British waters since 1850 are found below. And no… there is no “quiz item” here. This is just so unreal, that I thought it needed to be said here to get the full attention it deserves:

• Cod 98% • Haddock 90% • Plaice 90% • Whiting 70% • Halibut 98% • Turbot 95%

9) In the space below, describe one potential way (strategy) of dealing with the overfishing crisis. Several were mentioned in the articles and may be acceptable if defended appropriately. (2 pts.) 10) What will likely happen to many of the shrimpers (shrimp fishermen) in the Louisiana, USA region in the long-term as a result of the damage caused by Hurricane Katrina? (2 pts.) 11) The largest shrimp-producing country in the world is: a) India b) China c) Vietnam

d) Thailand

12) Most of the world’s fisheries are: coasta l or open ocean . (circle one of the two and provide one supporting reason this is so - 2pts.) 13) Name and describe one species mentioned in the text (Ch. 17) as a potentially-valuable “new fishery” for the future: (2 pts.)
