fishery
wild fishing
capture fishing
aquaculture
Advancement in fishing technology have had what results?
damage to habitats
increasing sustainable yields of wild fishing
increased reproduction of fish stocks
reduction in wild populations
One example of INDIVIDUAL mitigation of dwindling fish stocks would be -
Joining Greenpeace and going on marches
Collect food waste and place it in a domestic composter
Learn about and choose to consume only non-endangered fish species
Choosing to stop eating red meat and only consume fish
One example of INTERNATIONAL mitigation of dwindling wild fish stocks would be -
Federal endangered species list
Legislation to manage zonation of coastal habitat land use
International fishing quotas
International fleets of trawlers

If we harvest greater amounts of aquatic organisms than are what is replaced through reproduction, this would be considered -
sustainable fishing
maximum sustainable yield
unsustainable fishing
optimal sustainable yield
Which nation seems to have reduced the unsustainable fishing of cod and increased the wild populations?
Japan
Iceland
Newfoundland (Canada)
Brazil
What is a maximum sustainable yield?
The highest amount which can be taken which will permanently deplete the stock
The highest amount which can be taken without permanently depleting the stock
The highest amount which can be taken without permanently depleting the stock even on a poor recruitment year
An amount under the highest amount of stock which is replaced each year as natural capital
62% of all farmed fish worldwide is from China. Oftentimes, fish are cultivated inside the rice paddies so their waste fertilizes the rice. This can be considered -
Polyculture
Monoculture
Commercial harvesting
Mutualism
Which of these are negative impacts of aquaculture?
Eutrophication from feed which washed out of the farm
Larger incidence of diseases because of high density stocking
Greater economies for the local aquaculture workers
Escaped fish outcompeting native species in the natural ecosystem
Access to cheaper protein sources for poorer people

False
