Sustainable Fishery SR 11 NAME: _______________________________
1. Describe
the conventional idea of a sustainable fishery.
2.
Sustainability
in fisheries combines
theoretical disciplines, such as the population
dynamics of fisheries, with practical strategies, to avoid
________________ .
3. Are global wild fish populations increasing, peaking or in decline?
4. What is the status of valuable wild fish habitats?
5. Why is aquaculture, or fish farming, not a solution to the problems with the wild fishery?
6.
What was ironic about Thomas HuxleyÕs inaugural
address to the International Fisheries Exhibition in London in 1883?
7. How is sustainability, to a great extent, like art, according to Ray Hilborn?
8.
Explain, briefly, the concept of
relationship farming.
9. What is the traditional definition of overfishing?
10. Today
over 70% of fish species are either fully exploited, overexploited, depleted,
or recovering from depletion. If overfishing does not decrease, when is it
predicted that stocks of all species currently commercially fished for will
collapse?
11. What
activity has literally flattened diversity in the benthic habitat, radically
changing the associated communities?
12. What effect is climate change having on fisheries?
13. Why is pollution not easy to fix?
14. Large
predator fish contain significant amounts of mercury. What are itÕs negative
effects?
15. How does aggressive irrigation exert itÕs negative effects on lakes?
16. Which of the following are actually one of the Ten Commandments for ecosystem-based fisheries scientists? Yes or No
_______ Keep a perspective that is holistic,
risk-adverse and adaptive.
_______ Eliminate an Òold growthÓ structure in
fish populations, since big, old and fat female fish have been shown to be the
best spawners, but are also susceptible to overfishing.
_______ Characterize and maintain the natural
spatial structure of fish stocks, so that management boundaries match natural
boundaries in the sea.
_______ Identify and maintain critical food-web
connections.
_______ Ignore the
actions of humans and their social and economic systems in all ecological
equations.
