Exploring Live Feed Culture

What are the two main types of live feed culture?

• Microalgae and zooplankton

• Plankton and phytoplankton

• Fish and crustaceans

• Bacteria and fungi

Why are live feeds crucial in the early culture stages of aquatic organisms?

• Live feeds can be replaced entirely by artificial feeds.

• Live feeds are not necessary for growth.

• Live feeds are primarily for decoration.

• Live feeds are crucial for nutrient supply and enhancing survival rates.

Some technologies used in the live feed culture industry include (a)   .

• Solar panel installations

• Virtual reality training modules

• Automated feeding systems

• Hydraulic lift systems

What is the primary role of phytoplankton in aquatic ecosystems?

• To produce oxygen and serve as the foundation of the aquatic food web.

• To consume other organisms in the water.

• To filter pollutants from the water.

• To provide shelter for aquatic animals.

How do zooplankton contribute to the food web in aquatic environments?

• Zooplankton feed on detritus and have no role in energy transfer.

• Zooplankton consume larger fish in the food web.

• Zooplankton are not involved in the aquatic food web.

• Zooplankton are a crucial food source in aquatic food webs, linking primary producers to higher trophic levels.

What are the benefits of using bioenrichment in live feed culture?

• Increased risk of disease in fish larvae from bioenriched feed.

• Decreased growth rates in fish larvae due to lower feed quality.

• Higher costs associated with sourcing live feed without nutritional benefits.

• Improved nutritional quality of live feed, leading to better growth and survival rates in fish larvae.

How does artificial intelligence enhance aquaculture management?

• AI focuses on breeding new fish species.

• AI eliminates the need for fish feed.

• AI reduces water usage in aquaculture.

• AI improves aquaculture management through data analytics for monitoring, prediction, optimization, and early disease detection.

The advantages of using algae photobioreactors include (a)   .

• Limited growth potential
• High energy consumption
• Inability to produce oxygen
• Advantages of using algae photobior

What role do natural polyunsaturated fatty acids (PUFA) play in the growth of aquatic larvae?

• PUFAs are harmful to aquatic larvae growth.

• PUFAs are essential for the growth and development of aquatic larvae.

• PUFAs have no impact on aquatic larvae development.

• PUFAs are only beneficial for adult fish.

Match the following reasons for reducing reliance on artificial feeds in aquaculture with their corresponding explanations.

• To reduce the nutritional value of fish diets.

• It is important to reduce reliance on artificial feeds in aquaculture to enhance sustainability, improve fish health, and lower costs.

• To promote the use of more expensive feed alternatives.

• To reduce the nutritional value of fish diets.

• It is important to reduce reliance on artificial feeds in aquaculture to enhance sustainability, improve fish health, and lower costs.

• To promote the use of more expensive feed alternatives.

• To increase the use of chemicals in fish farming.

• To increase the use of chemicals in fish farming.
