Fish Farming Practices and Challenges

The video discusses fish farming as a solution to overfishing, detailing methods to enhance yield. It covers controlling predation, managing disease and pests, optimizing diet and water quality, and selective breeding. These strategies aim to maximize fish growth and farm profitability.

What is one of the main reasons for the decline in fish stocks in the oceans?

• Pollution

• Overfishing

• Climate change

• Natural disasters

How can interspecific predation be prevented in fish farms?

• Feeding high-protein pellets

• Using antibiotics

• Increasing water temperature

• Using nets to cover the fish

What is a method to control intraspecific predation in fish farms?

• Increasing tank size

• Feeding them less frequently

• Using pesticides

• Separating fish by age and size

Which of the following is a method to control disease in fish farms?

• Increasing the number of fish

• Using pesticides and antibiotics

• Reducing water filtration

• Feeding them less frequently

What is the purpose of using wrasse in fish farms?

• To increase fish size

• To eat sea lice

• To improve water quality

• To breed with other fish

What is a potential issue with using fish pellets made from smaller fish?

• They are too expensive

• They cause a decrease in wild fish species

• They are not nutritious

• They dissolve in water

Why is it important to maintain optimal water quality in fish tanks?

• To ensure maximum growth and health

• To reduce feeding costs

• To increase tank size

• To prevent fish from escaping

What is the goal of selective breeding in fish farming?

• To reduce the size of fish

• To create more colorful fish

• To produce fish that grow rapidly with less food

• To increase the number of fish species

How can water quality be monitored in fish tanks?

• By tasting the water

• Using sensors to monitor pH, temperature, and oxygen levels

• By observing fish behavior

• By adding more fish

What is one benefit of selective breeding in fish farming?

• Decreased fish size

• Reduced need for water filtration

• Higher yield and profit

• Increased fish color variety
