All Flashcards
How do catch limits help prevent overfishing?
Setting quotas prevents over-harvesting, allowing populations to recover.
How do size limits promote sustainable fishing?
Allows fish to reach reproductive maturity before capture.
How do Marine Protected Areas aid in sustainability?
Restricting fishing allows fish populations to recover and thrive.
How does selective gear help?
Minimizes bycatch, reducing the impact on non-target species.
How can improved regulations help?
Better laws and enforcement protect fish populations.
What is overfishing?
Catching fish faster than they can reproduce, leading to population decline.
Define 'bycatch'.
Accidental capture of non-target species during fishing.
What are Marine Protected Areas (MPAs)?
Areas where fishing is restricted or prohibited to allow fish populations to recover.
What is bottom trawling?
A fishing method that drags a large net along the seafloor, destroying habitats.
Define 'catch limits'.
Quotas on how many fish can be caught.
What are 'size limits' in fishing?
Regulations that only allow the capture of mature fish.
What is 'selective gear'?
Fishing gear that minimizes bycatch (accidental capture of non-target species).
What is the 'Tragedy of the Commons'?
Shared resources are overused when individuals act in their own self-interest.
How does overfishing relate to the 'Tragedy of the Commons'?
Overfishing exemplifies the tragedy; a shared resource (ocean) is depleted by individual exploitation.
Explain the concept of 'sustainable fishing'.
Fishing practices that maintain fish populations and ecosystem health for the future.
Why is biodiversity loss a concern in the context of overfishing?
Overfishing can lead to the decline or extinction of certain marine species, reducing biodiversity.
How does overfishing impact marine food webs?
It disrupts the balance by removing key species, affecting predators and prey.
Explain the link between overfishing and habitat destruction.
Destructive fishing methods like bottom trawling damage seafloor habitats.
