What is the primary goal of sustainable aquaculture?

  1. Maximizing fish production without regard to environmental impact

  2. Balancing fish production with the preservation of aquatic ecosystems

  3. Using chemicals and antibiotics to prevent diseases in farmed fish

  4. Releasing farmed fish into natural water bodies to increase wild fish populations

Show answer
Correct Option: B
Explanation:

Sustainable aquaculture aims to strike a balance between meeting the demand for fish products and protecting the health of aquatic environments.

Which of the following is a key challenge in sustainable aquaculture?

  1. Overcrowding of fish in aquaculture facilities

  2. Insufficient supply of fish feed

  3. Lack of access to clean water sources

  4. All of the above

Show answer
Correct Option: D
Explanation:

Sustainable aquaculture faces multiple challenges, including overcrowding, feed supply, water quality, and disease management.

What is the term for the practice of raising fish in enclosures in open water?

  1. Cage aquaculture

  2. Pond aquaculture

  3. Recirculating aquaculture systems

  4. Aquaponics

Show answer
Correct Option: A
Explanation:

Cage aquaculture involves raising fish in net enclosures placed in open water bodies like lakes or oceans.

What is the primary source of protein in fish feed used in aquaculture?

  1. Soybean meal

  2. Fish meal

  3. Cornmeal

  4. Wheat flour

Show answer
Correct Option: B
Explanation:

Fish meal, made from processed fish, is a common source of protein in aquaculture feed.

What is the term for the process of recycling water in aquaculture systems?

  1. Recirculating aquaculture systems

  2. Aquaponics

  3. Biofiltration

  4. Phytoremediation

Show answer
Correct Option: A
Explanation:

Recirculating aquaculture systems involve treating and reusing water in aquaculture facilities, reducing water consumption and waste discharge.

What is the term for the practice of integrating fish farming with plant cultivation?

  1. Aquaculture

  2. Aquaponics

  3. Hydroponics

  4. Aeroponics

Show answer
Correct Option: B
Explanation:

Aquaponics combines fish farming and plant cultivation, where fish waste provides nutrients for plants, and plants help purify water for fish.

What is the primary concern regarding the use of antibiotics in aquaculture?

  1. Development of antibiotic-resistant bacteria

  2. Increased fish mortality

  3. Reduced water quality

  4. All of the above

Show answer
Correct Option: A
Explanation:

The overuse of antibiotics in aquaculture can lead to the development of antibiotic-resistant bacteria, posing a threat to human and animal health.

What is the term for the practice of releasing farmed fish into natural water bodies?

  1. Stocking

  2. Enhancement

  3. Translocation

  4. Introduction

Show answer
Correct Option: A
Explanation:

Stocking involves releasing farmed fish into natural water bodies to supplement wild fish populations.

What is the primary concern regarding the release of farmed fish into natural water bodies?

  1. Competition with wild fish for food and habitat

  2. Introduction of diseases and parasites to wild fish populations

  3. Genetic dilution of wild fish populations

  4. All of the above

Show answer
Correct Option: D
Explanation:

Releasing farmed fish into natural water bodies can have negative impacts on wild fish populations, including competition, disease transmission, and genetic dilution.

What is the term for the practice of using natural or artificial barriers to prevent the escape of farmed fish from aquaculture facilities?

  1. Containment

  2. Enclosure

  3. Confinement

  4. Isolation

Show answer
Correct Option: A
Explanation:

Containment measures aim to prevent the escape of farmed fish from aquaculture facilities, reducing the risk of interactions with wild fish populations.

What is the primary concern regarding the use of chemicals in aquaculture?

  1. Pollution of water bodies

  2. Harm to aquatic organisms

  3. Accumulation of chemicals in fish tissues

  4. All of the above

Show answer
Correct Option: D
Explanation:

The use of chemicals in aquaculture can have negative impacts on water quality, aquatic organisms, and the safety of fish products for human consumption.

What is the term for the practice of using natural ecosystems to treat wastewater from aquaculture facilities?

  1. Constructed wetlands

  2. Bioremediation

  3. Phytoremediation

  4. Natural treatment systems

Show answer
Correct Option: A
Explanation:

Constructed wetlands are engineered ecosystems designed to treat wastewater from aquaculture facilities using natural processes.

What is the primary goal of sustainable aquaculture certification programs?

  1. Ensuring the quality and safety of fish products

  2. Promoting responsible aquaculture practices

  3. Reducing the environmental impact of aquaculture

  4. All of the above

Show answer
Correct Option: D
Explanation:

Sustainable aquaculture certification programs aim to promote responsible aquaculture practices, ensure the quality and safety of fish products, and reduce the environmental impact of aquaculture.

What is the term for the practice of using fish waste as a fertilizer in agriculture?

  1. Aquaculture-agriculture integration

  2. Aquaponics

  3. Fertigation

  4. Nutrient recycling

Show answer
Correct Option: C
Explanation:

Fertigation involves using fish waste as a liquid fertilizer in agriculture, providing nutrients for crops and reducing the need for chemical fertilizers.

What is the primary goal of sustainable aquaculture research?

  1. Developing new aquaculture technologies

  2. Improving the efficiency of aquaculture production

  3. Reducing the environmental impact of aquaculture

  4. All of the above

Show answer
Correct Option: D
Explanation:

Sustainable aquaculture research aims to develop new technologies, improve production efficiency, and reduce the environmental impact of aquaculture.
