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.
