Environmental Sciences: Fishing

Mr. Andersen discusses the impact of fishing on the environment, highlighting the problem of overfishing and the Tragedy of the Commons. He explains various fishing techniques and the concept of sustainable yield. The video also covers the collapse of the North Atlantic Cod fishery and the role of aquaculture in addressing overfishing. Sustainable practices and regulations, including quotas, are emphasized as solutions to maintain healthy fish populations.

What is a significant issue caused by commercial fishing?

• Overfishing

• Increased tourism

• Decreased seafood demand

• Improved fish quality

Which of the following is NOT a traditional fishing technique?

• Hand and spear

• Trapping

• Angling

• Aquaculture

What is the 'Tragedy of the Commons' in the context of fishing?

• A technique for sustainable fishing

• A situation where shared resources are overused

• A method to increase fish population

• A type of fishery management

Which event is a classic example of overfishing?

• Collapse of the North Atlantic Cod fishery

• Increase in aquaculture

• Introduction of fishing quotas

• Rise in seafood prices

What does the concept of 'sustainable yield' aim to achieve?

• Maximize fish catch regardless of population

• Maintain a healthy fish population

• Reduce fishing regulations

• Increase fish prices

What happens to a fish population if the catch rate matches the growth rate?

• The population increases

• The population becomes extinct

• The population decreases

• The population remains stable

What is a major benefit of aquaculture?

• It eliminates the need for fishing regulations

• It allows for a greater density of fish

• It increases the biodiversity of wild fish

• It reduces the need for fish farming

What is a potential downside of aquaculture?

• It can lead to waste management issues

• It reduces fish waste

• It requires no antibiotics

• It decreases fish density

How can regulations help in sustainable fishing?

• By increasing the total allowable catch

• By setting quotas for individual fishermen

• By eliminating fishing seasons

• By reducing fish prices

What is a concern with genetically modified fish in aquaculture?

• They grow slower than wild fish

• They do not compete with native species

• They are less nutritious

• They can escape and affect biodiversity
