Aquaculture Concepts and Practices

Mr. Smith introduces aquaculture, comparing it to agriculture but in water. The video covers the benefits, such as efficient land use and reduced risk of fishery collapse, and drawbacks, including waste concentration and disease spread. Sustainable practices are discussed, and students are encouraged to identify advantages and environmental consequences of aquaculture.

What is aquaculture primarily concerned with?

• Mining underwater resources

• Raising terrestrial animals

• Raising aquatic species

• Growing plants on land

Which of the following is a benefit of aquaculture?

• Increased land usage

• Decreased water pollution

• Higher fuel consumption

• Prevention of fishery collapse

How does aquaculture compare to traditional meat production in terms of land usage?

• It does not use land at all

• It uses the same amount of land

• It uses less land

• It uses more land

Which of the following can be considered a form of aquaculture?

• Mining coal

• Organic shellfish farming

• Raising cattle

• Growing wheat

What is a sustainable practice in aquaculture?

• Releasing waste into the ocean

• Overfishing wild populations

• Using excessive antibiotics

• Using fish waste as nutrient input

What is a major drawback of aquaculture related to waste?

• Reduced water temperature

• Increased land usage

• High waste concentration

• Decreased fish growth

How can aquaculture contribute to disease spread?

• By reducing the need for antibiotics

• By allowing diseases to spread to wild populations

• By keeping fish in low-density environments

• By isolating fish from wild populations

What is a potential risk of using antibiotics in aquaculture?

• Increased fish size

• Endocrine disruption in aquatic ecosystems

• Decreased water temperature

• Improved fish health

What environmental consequence can result from non-native species escaping aquaculture enclosures?

• Decreased fish population

• Becoming invasive species

• Formation of new ecosystems

• Improved biodiversity

What is the practice exercise for topic 5.16 focused on?

• Describing advantages and disadvantages of aquaculture

• Designing aquaculture enclosures

• Identifying fish species

• Calculating fish growth rates
