What is the term used to describe the unintended capture of non-target species during fishing operations?

  1. Overfishing

  2. Bycatch

  3. Depletion

  4. Ghost fishing


Correct Option: B

What is the term used to describe the practice of returning fish to the water after they have been caught?

  1. Catch and release

  2. Selective fishing

  3. Aquaculture

  4. Marine protected areas


Correct Option: A

Which fishing method involves dragging a weighted net along the seafloor, often resulting in habitat destruction?

  1. Trawling

  2. Dredging

  3. Longlining

  4. Gillnetting


Correct Option: A
Explanation:

What is the term used to describe areas of the ocean that are designated for the protection of marine life and habitats?

  1. Marine protected areas

  2. Fishery management zones

  3. Exclusive economic zones

  4. Territorial waters


Correct Option: A
Explanation:

Marine protected areas (MPAs) are designated areas of the ocean where fishing and other human activities are restricted or prohibited in order to protect marine life and habitats.

Which fishing practice involves setting a series of baited hooks on a long line?

  1. Trawling

  2. Dredging

  4. Gillnetting


Correct Option: C
Explanation:

Longlining is a fishing method that involves setting a series of baited hooks on a long line, which is then left in the water for a period of time.

What is the term used to describe the practice of farming fish in controlled environments?

  3. Bycatch

  4. Ghost fishing


Correct Option: A
Explanation:
