Salmon Farming Practices and Challenges

The video discusses the evolution of salmon farming from traditional coastal methods to innovative land-based systems. Traditional methods, while popular, pose significant risks to marine ecosystems, including disease transmission and genetic interference with wild populations. Land-based salmon farms offer a sustainable alternative, allowing for controlled environments that maintain optimal water quality. These farms can be established anywhere, reducing shipping emissions and utilizing fish waste for eco-friendly fertilizer production.

What is one of the main challenges of farming salmon on land?

• Salmon are too expensive to farm.

• Salmon require too much space.

• Salmon are sensitive to water quality changes.

• Salmon are not popular enough.

How are salmon traditionally farmed?

• In floating pens in coastal waters.

• In underground aquifers.

• In land-based tanks.

• In freshwater lakes.

What environmental issue is associated with traditional salmon farming?

• Release of nitrogen and phosphorus into the ocean.

• Deforestation.

• Increased air pollution.

• Depletion of freshwater resources.

What is a potential problem when farmed salmon escape into the wild?

• They might not survive in the wild.

• They could become predators to other fish.

• They could breed with wild salmon, affecting the gene pool.

• They might overpopulate the ocean.

What is a benefit of land-based salmon farms?

• They are cheaper to maintain.

• They can be built anywhere, reducing shipping emissions.

• They produce more salmon than traditional farms.

• They require less water.

How can waste from land-based salmon farms be utilized?

• To create eco-friendly fertilizer.

• As a source of renewable energy.

• To purify water.

• To feed other fish species.
