What is the primary goal of sustainable fisheries?

  1. To maximize fish catch for economic gain.

  2. To maintain healthy fish populations and ecosystems.

  3. To reduce bycatch and minimize environmental impact.

  4. To ensure fair and equitable access to fisheries resources.


Correct Option: B
Explanation:

Sustainable fisheries aim to balance the needs of fishing communities and the long-term health of fish populations and their ecosystems.

Which fishing method is generally 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 method that targets specific fish species while minimizing bycatch and habitat damage.

What is the term for the unintended capture of non-target species during fishing operations?

  1. Overfishing

  2. Bycatch

  3. Ghost fishing

  4. Aquaculture


Correct Option: B
Explanation:

Bycatch refers to the incidental capture of non-target species, which can have negative impacts on marine ecosystems.

What is the main environmental concern associated with aquaculture?

  1. Habitat destruction

  2. Water pollution

  3. Disease transmission

  4. All of the above


Correct Option: D
Explanation:

Aquaculture can lead to habitat destruction, water pollution, and disease transmission, if not managed sustainably.

Which aquaculture system is designed to minimize environmental impact by recirculating and treating water?

  1. Open-ocean aquaculture

  2. Cage aquaculture

  3. Flow-through aquaculture

  4. Recirculating aquaculture system (RAS)


Correct Option: D
Explanation:

RAS is a closed-loop system that recirculates and treats water, reducing the environmental impact of aquaculture.

What is the term for the practice of releasing hatchery-raised fish into natural waters to supplement wild populations?

  1. Stock enhancement

  2. Aquaculture

  3. Selective breeding

  4. Fish farming


Correct Option: A
Explanation:

Stock enhancement aims to increase the abundance of wild fish populations by releasing hatchery-raised fish.

What is the role of marine protected areas (MPAs) in sustainable fisheries management?

  1. To provide safe havens for fish to reproduce and grow.

  2. To reduce fishing pressure on certain areas.

  3. To protect critical habitats and ecosystems.

  4. All of the above


Correct Option: D
Explanation:

MPAs serve multiple purposes, including providing safe havens for fish, reducing fishing pressure, and protecting critical habitats.

Which international organization is responsible for setting global standards for sustainable fishing practices?

  1. World Trade Organization (WTO)

  2. Food and Agriculture Organization (FAO)

  3. World Health Organization (WHO)

  4. United Nations Environment Programme (UNEP)


Correct Option: B
Explanation:

The FAO is responsible for developing and promoting sustainable fishing practices worldwide.

What is the term for the practice of reducing the number of fishing vessels or fishing effort to ensure sustainable fish populations?

  1. Catch quotas

  2. Effort control

  3. Marine protected areas (MPAs)

  4. Selective breeding


Correct Option: B
Explanation:

Effort control involves limiting the number of fishing vessels or fishing effort to prevent overfishing.

Which technology is used to track the movement and behavior of fish populations?

  1. Satellite tagging

  2. Acoustic telemetry

  3. Remote sensing

  4. All of the above


Correct Option: D
Explanation:

Satellite tagging, acoustic telemetry, and remote sensing are all technologies used to study fish populations.

What is the role of consumer choices in promoting sustainable fisheries?

  1. Choosing seafood from sustainable sources.

  2. Reducing seafood consumption.

  3. Supporting local fisheries.

  4. All of the above


Correct Option: D
Explanation:

Consumer choices, such as choosing seafood from sustainable sources, reducing seafood consumption, and supporting local fisheries, can contribute to sustainable fisheries management.

Which type of aquaculture involves raising fish in large, open-water enclosures?

  1. Cage aquaculture

  2. Flow-through aquaculture

  3. Recirculating aquaculture system (RAS)

  4. Open-ocean aquaculture


Correct Option: D
Explanation:

Open-ocean aquaculture involves raising fish in large, open-water enclosures in the ocean.

What is the term for the practice of farming aquatic plants for food, fuel, or other products?

  1. Aquaculture

  2. Mariculture

  3. Aquaponics

  4. Phycoremediation


Correct Option: A
Explanation:

Aquaculture encompasses the farming of aquatic organisms, including fish, shellfish, and aquatic plants.

Which type of aquaculture involves raising fish in tanks or ponds on land?

  1. Cage aquaculture

  2. Flow-through aquaculture

  3. Recirculating aquaculture system (RAS)

  4. Land-based aquaculture


Correct Option: D
Explanation:

Land-based aquaculture involves raising fish in tanks or ponds on land, often in controlled environments.

What is the term for the practice of using waste from aquaculture operations to fertilize crops?

  1. Aquaponics

  2. Mariculture

  3. Phycoremediation

  4. Bioremediation


Correct Option: A
Explanation:

Aquaponics is a system that combines aquaculture and hydroponics, using waste from aquaculture operations to fertilize crops.
