Aquatic Food Production Systems Quiz

What percentage of the world's fisheries are fully exploited, in decline, seriously depleted, or too low to allow recovery?

• 30%

• 50%

• 70%

• 90%

What is the Maximum Sustainable Yield (MSY)?

• The highest amount of fish that can be caught without any impact on the population

• The highest amount of fish that can be caught without permanently depleting the stock

• The maximum number of fish that can be caught in a year

• The total number of fish in a given area

What is the continental shelf and why is it important for food production?

• It is the extension of continents under the seas and oceans, and it has 50% of oceanic productivity but 15% of its area

• It is the deepest part of the ocean and has the highest fish population

• It is the area where aquaculture is prohibited

• It is the region where international waters begin

What is aquaculture and how is it different from wild capture?

• Aquaculture is the hunting of wild fish, while wild capture is the farming of terrestrial animals

• Aquaculture is the capture of wild fish, while wild capture is the farming of aquatic organisms

• Aquaculture is the farming of aquatic organisms, while wild capture is the capture of wild fish

• Aquaculture is the farming of terrestrial animals, while wild capture is the hunting of wild animals

What are some ways in which aquaculture might be more sustainable than other food production systems?

• It causes loss of habitats and pollution

• It spreads diseases and leads to overfishing

• It uses more trimmings and scraps, and substitutes fishmeal with livestock and poultry processing waste

• It leads to population decline and loss of resource base

What are some reasons for the decline of wild fisheries?

• Indiscriminate fishing gear and smaller fishing fleets

• More and better technology and larger fishing fleets

• Lack of technology and refrigeration techniques

• Lack of demand for fish and smaller fishing fleets

What is the impact of harvesting the Maximum Sustainable Yield (MSY) on fish populations?

• It has no impact on the fish population

• It leads to population decline and loss of resource base

• It leads to overfishing and depletion of the stock

• It leads to an increase in the fish population
