Chapter 18 Flashcards
- What does sustainable management of a renewable resource involve?
Sustainable management of a new renewable resource involves maintaining the resource’s source and sink functions in such a way that its quality and availability remain stable over time.
- What is the maximum sustainable yield of a renewable resource?
The maximum sustainable yield of a renewable resource is the maximum quantity of a natural resource that can be harvested annually without depleting the stock or population of the resource.
What is a logistic curve?
An S-shaped growth curve tending toward an upper limit.
- What happens if the population of a species falls below the critical level?
If the population of a species falls below the critical level (minimum level to survive), then it will reach extinction.
- What is the economic optimum yield level for a fishery?
The economic optimum yield level for a fishery is when the benefit is the highest while still being ecologically sustainable.
- What is the open-access equilibrium for a fishery?
The open-access equilibrium for a fishery is when more effort to catch the fish is higher due to fish population stick being low.
- How might the economic optimum yield level for a fishery be obtained?
It’s obtained when fish population stocks are relatively high.
What is a bycatch?
The harvesting of aquatic organisms other than the intended commercial species
- What is the status of the world’s fish stocks?
As of 2017,
6% of the fish stocks were classified as underfished,
60% were maximally sustainably fished, and
34% were overfished.
- What is the 1982 Law of the Sea?
An United Nations treaty in which countries can claim territorial rights to many important offshore fisheries by requiring a fishing license within their zone.
- What policies could be instituted to encourage sustainable fishery management?
Requiring fishing licenses for fisheries to fish within an Exclusive Economic Zone and having individual transferable quotas.
What are individual transferable quotas (ITQs)?
Tradable rights to harvest a resource, such as a permit to harvest a particular quantity of fish.
What is ecolabeling?
A label on a good that provides information concerning the environmental impacts that resulted from the production of the good.
How can ecolabeling be used?
It could be used to encourage sustainable fishery management by providing fisheries financial incentives because consumers pay more for a good if it was sustainably produced.
