What is the primary goal of sustainable fisheries management?

  1. To maximize fish catches for short-term economic gains.

  2. To balance fishing activities with the long-term health of fish populations and marine ecosystems.

  3. To eliminate all fishing practices to protect marine life.

  4. To prioritize the needs of commercial fishing over artisanal fishing.


Correct Option: B
Explanation:

Sustainable fisheries management aims to ensure that fishing activities are conducted in a way that maintains the health and productivity of fish populations and marine ecosystems, while also considering the economic and social well-being of fishing communities.

Which fishing practice is known for its low bycatch and minimal impact on marine ecosystems?

  1. Trawling

  2. Gillnetting

  3. Longlining

  4. Pole-and-line fishing


Correct Option: D
Explanation:

Pole-and-line fishing is a selective fishing method that targets specific fish species without harming other marine life. It involves using a fishing pole and line to catch fish individually, reducing bycatch and minimizing the impact on marine ecosystems.

What is the term used to describe the practice of returning undersized or unwanted fish to the water?

  1. Catch and release

  2. Bycatch reduction

  3. Selective fishing

  4. Fish discarding


Correct Option: A
Explanation:

Catch and release is a fishing practice where anglers intentionally return undersized or unwanted fish to the water. This helps to reduce fishing mortality and allows fish populations to replenish themselves.

Which international agreement aims to promote responsible fishing practices and the conservation of marine resources?

  1. The Paris Agreement

  2. The Kyoto Protocol

  3. The United Nations Convention on the Law of the Sea (UNCLOS)

  4. The Montreal Protocol


Correct Option: C
Explanation:

The United Nations Convention on the Law of the Sea (UNCLOS) is an international agreement that sets out a comprehensive framework for the conservation and management of marine resources, including fisheries.

What is the term used to describe the practice of managing fish populations by setting catch limits and quotas?

  1. Aquaculture

  2. Fish farming

  3. Total allowable catch (TAC)

  4. Marine protected areas (MPAs)


Correct Option: C
Explanation:

Total allowable catch (TAC) is a fisheries management tool that sets limits on the amount of fish that can be caught from a specific fish population during a given period.

Which fishing practice involves setting a long line with multiple baited hooks?

  1. Trawling

  2. Gillnetting

  3. Longlining

  4. Pole-and-line fishing


Correct Option: C
Explanation:

Longlining is a fishing practice that involves setting a long line with multiple baited hooks. This method is often used to catch tuna, swordfish, and other large pelagic fish.

What is the term used to describe the practice of using artificial reefs to attract and support marine life?

  1. Aquaculture

  2. Fish farming

  3. Artificial reef creation

  4. Marine protected areas (MPAs)


Correct Option: C
Explanation:

Artificial reef creation is the practice of constructing structures on the seabed to attract and support marine life. These structures can be made from a variety of materials, such as concrete, rocks, and shipwrecks.

Which fishing practice involves dragging a large net along the seabed to catch fish?

  1. Trawling

  2. Gillnetting

  3. Longlining

  4. Pole-and-line fishing


Correct Option: A
Explanation:

Trawling is a fishing practice that involves dragging a large net along the seabed to catch fish. This method is often used to catch bottom-dwelling fish, such as cod, haddock, and flounder.

What is the term used to describe the practice of protecting specific areas of the ocean from fishing activities?

  1. Aquaculture

  2. Fish farming

  3. Artificial reef creation

  4. Marine protected areas (MPAs)


Correct Option: D
Explanation:

Marine protected areas (MPAs) are designated areas of the ocean that are protected from fishing and other human activities. These areas are established to conserve marine ecosystems and biodiversity.

Which fishing practice involves setting a net that hangs vertically in the water to catch fish?

  1. Trawling

  2. Gillnetting

  3. Longlining

  4. Pole-and-line fishing


Correct Option: B
Explanation:

Gillnetting is a fishing practice that involves setting a net that hangs vertically in the water to catch fish. This method is often used to catch fish that swim in mid-water, such as salmon, tuna, and mackerel.

What is the term used to describe the practice of raising fish in captivity for food or other purposes?

  1. Aquaculture

  2. Fish farming

  3. Artificial reef creation

  4. Marine protected areas (MPAs)


Correct Option: A
Explanation:

Aquaculture is the practice of raising fish in captivity for food or other purposes. This method can help to reduce pressure on wild fish populations and provide a sustainable source of seafood.

Which fishing practice involves using a hook and line to catch fish?

  1. Trawling

  2. Gillnetting

  3. Longlining

  4. Pole-and-line fishing


Correct Option: D
Explanation:

Pole-and-line fishing is a fishing practice that involves using a hook and line to catch fish. This method is often used to catch fish that swim near the surface of the water, such as tuna, mackerel, and salmon.

What is the term used to describe the practice of managing fish populations by setting minimum size limits for fish that can be caught?

  1. Aquaculture

  2. Fish farming

  3. Minimum size limits

  4. Marine protected areas (MPAs)


Correct Option: C
Explanation:

Minimum size limits are a fisheries management tool that sets the minimum size of fish that can be caught. This helps to protect juvenile fish and allows them to reach reproductive maturity before being caught.

Which fishing practice involves using a large net to encircle a school of fish?

  1. Trawling

  2. Gillnetting

  3. Longlining

  4. Purse seining


Correct Option: D
Explanation:

Purse seining is a fishing practice that involves using a large net to encircle a school of fish. The net is then drawn closed at the bottom, trapping the fish inside.

What is the term used to describe the practice of using sound waves to locate and catch fish?

  1. Aquaculture

  2. Fish farming

  3. Sonar fishing

  4. Marine protected areas (MPAs)


Correct Option: C
Explanation:

Sonar fishing is the practice of using sound waves to locate and catch fish. This method is often used to catch fish that swim in deep water, such as tuna, swordfish, and marlin.
