For a quota to be successful…

• It must be set at the maximum amount that the consumers will purchase each year.

• It must be set at or above the maximum sustainable yield for the fishery.

• It must be set at or below the maximum sustainable yield for the fishery.

• Quotas have not been shown to be successful in preventing fish stock collapse.

What ecological harm can result from a fish pen used to raise a single species?

• Stray organisms end up in the pens. This is called bycatch.

• Fish sewage/waste flows out of the pens, potentially causing hypoxia.

• This practice increases the demand for wild-caught fish.

• The fish in the pens raise the temperature of the surrounding waters.

The fish was raised in an aquaculture facility.

• Farmed

• Wild-caught

• MSC Certified

The fish grew in the wild (ocean, lake, etc), and was caught and harvested by fishermen.

• Farmed

• Wild-caught

• MSC Certified

The fish has been sourced from a fishery or facility that pledges to abide by specific standards and practices that promote sustainablity.

• Farmed

• Wild-caught

• MSC Certified

Ecologists have detected increased concentrations of nitrogen-based compounds, such as ammonia, nitrates, and nitrites in the waters near the pens.  If allowed to continue, how will this affect the coastal ecosystem?
