Aquaculture Systems bab 1.1 &1.2

What is one benefit of modern aquaculture systems?

• Increased fish production efficiency

• Higher salinity levels

• Decreased water use

• Less biodiversity

Which type of water is characterized by a salinity of less than 0.5 ppt?

• Marine water

• Saltwater

• Brackish water

• Freshwater

What is a primary advantage of Recirculating Aquaculture Systems (RAS)?

• Increases wild fish harvesting

• Uses 90-99% less water

• Requires more land

• Decreases fish health

Which species is commonly farmed in freshwater aquaculture?

• Grouper

• Tilapia

• Salmon

• Snapper

What is a disadvantage of indoor aquaculture?

• Lower setup cost

• Requires technical expertise

• Uses natural sunlight

• Suitable for large-scale production

What type of aquaculture water is used for species like seabass?

• Rainwater

• Saltwater

• Brackish water

• Freshwater

How does aquaculture help reduce pressure on wild fisheries?

• By decreasing fish farming

• By increasing wild fish populations

• By providing alternative fish sources

• By promoting overfishing

What is a characteristic of outdoor aquaculture?

• Use of tanks

• Controlled environment

• Natural light and water sources

• High capital cost

Which of the following is a strategic advantage of aquaponics?

• Limited species diversity

• Higher energy consumption

• Integration with hydroponics

• Increased water pollution

What is a common disadvantage of outdoor aquaculture?

• Year-round production

• Vulnerability to weather

• High capital cost

• Requires technical expertise
