What is the primary goal of sustainable fishing practices?

  1. To maximize fish catch for economic gain

  2. To protect and conserve fish populations for future generations

  3. To reduce the number of fish in the ocean

  4. To increase the number of fishing vessels in operation


Correct Option: B
Explanation:

Sustainable fishing practices aim to ensure that fish stocks are not depleted and that fishing activities do not harm marine ecosystems.

Which fishing method is considered to be the most sustainable?

  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 and minimizes bycatch. It also has a low impact on the marine environment.

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

  1. Bycatch

  2. Discarding

  3. Releasing

  4. Selective fishing


Correct Option: B
Explanation:

Discarding refers to the practice of throwing back unwanted fish into the water. This can be done for various reasons, such as the fish being too small, the wrong species, or having low market value.

What is the purpose of establishing marine protected areas (MPAs) in sustainable fishing?

  1. To increase fishing pressure in specific areas

  2. To allow unrestricted fishing in certain zones

  3. To protect critical fish habitats and promote biodiversity

  4. To facilitate the construction of fishing infrastructure


Correct Option: C
Explanation:

MPAs are designated areas of the ocean where fishing and other extractive activities are restricted or prohibited. They serve as sanctuaries for fish populations to recover and reproduce, contributing to the overall health of marine ecosystems.

Which fishing gear is known for its high selectivity and reduced bycatch?

  1. Drift nets

  2. Bottom trawls

  3. Purse seines

  4. Hook and line


Correct Option: D
Explanation:

Hook and line fishing is a selective fishing method that involves using baited hooks to catch fish. It minimizes bycatch as fish are targeted individually, reducing the capture of non-target species and undersized fish.

What is the term used to describe the practice of managing fish stocks based on scientific data and assessments?

  1. Aquaculture

  2. Overfishing

  3. Stock assessment

  4. Fish farming


Correct Option: C
Explanation:

Stock assessment involves the collection and analysis of scientific data to determine the status of fish populations. This information is used to set fishing quotas and regulations to ensure sustainable fishing practices.

Which fishing technique involves surrounding a school of fish with a large net and then closing the bottom to capture them?

  1. Trawling

  2. Purse seining

  3. Longlining

  4. Gillnetting


Correct Option: B
Explanation:

Purse seining is a fishing technique where a large net is deployed around a school of fish, and the bottom of the net is closed to prevent their escape. This method is commonly used to catch pelagic fish species such as tuna and mackerel.

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

  1. Aquaculture

  2. Habitat restoration

  3. Marine protected areas

  4. Artificial reefing


Correct Option: D
Explanation:

Artificial reefing involves the deployment of man-made structures on the ocean floor to create habitats for fish and other marine life. These structures can be made from various materials, such as concrete, steel, or recycled materials.

Which fishing method involves dragging a weighted net along the ocean floor to catch bottom-dwelling fish?

  1. Trawling

  2. Longlining

  3. Gillnetting

  4. Pole and line fishing


Correct Option: A
Explanation:

Trawling is a fishing method where a large net is dragged along the ocean floor to catch bottom-dwelling fish species such as cod, haddock, and flounder. This method can have a significant impact on marine habitats and ecosystems.

What is the term used to describe the practice of managing fisheries to ensure that fish stocks are not depleted?

  1. Aquaculture

  2. Sustainable fishing

  3. Overfishing

  4. Fish farming


Correct Option: B
Explanation:

Sustainable fishing involves managing fisheries to ensure that fish stocks are not depleted and that fishing activities do not harm marine ecosystems. This includes setting fishing quotas, implementing regulations, and promoting responsible fishing practices.

Which fishing method involves setting a line with multiple baited hooks to catch fish?

  1. Trawling

  2. Longlining

  3. Gillnetting

  4. Pole and line fishing


Correct Option: B
Explanation:

Longlining is a fishing method where a long line with multiple baited hooks is set in the water to catch fish. This method is commonly used to catch fish species such as tuna, swordfish, and halibut.

What is the term used to describe the practice of using nets with mesh sizes that allow smaller fish to escape?

  1. Bycatch reduction devices

  2. Selective fishing

  3. Gillnetting

  4. Trawling


Correct Option: B
Explanation:

Selective fishing involves using fishing gear and techniques that minimize the capture of non-target species and undersized fish. This can be achieved through the use of nets with appropriate mesh sizes, hook sizes, and fishing methods that target specific species.

Which fishing method involves setting a net vertically in the water to catch fish that swim into it?

  1. Trawling

  2. Longlining

  3. Gillnetting

  4. Pole and line fishing


Correct Option: C
Explanation:

Gillnetting is a fishing method where a vertical net is set in the water to catch fish that swim into it and become entangled in the mesh. This method is commonly used to catch fish species such as salmon, herring, and mackerel.

What is the term used to describe the practice of using fishing gear that minimizes the impact on marine habitats?

  1. Habitat-friendly fishing

  2. Sustainable fishing

  3. Overfishing

  4. Aquaculture


Correct Option: A
Explanation:

Habitat-friendly fishing involves using fishing gear and techniques that minimize the damage to marine habitats. This can include using gear that does not disturb the seafloor, avoiding areas with sensitive habitats, and using biodegradable materials.

Which fishing method involves using a pole with a line and baited hook to catch fish?

  1. Trawling

  2. Longlining

  3. Gillnetting

  4. Pole and line fishing


Correct Option: D
Explanation:

Pole and line fishing is a fishing method where a pole with a line and baited hook is used to catch fish. This method is commonly used to catch fish species such as tuna, marlin, and sailfish.
