Question 1

Which of the following statements about the Atlantic cod is FALSE?

Accepted Answer

All of these statements are true.

Question 2

Which of the following statements is FALSE?

Accepted Answer

All of the statements are true.

Question 3

Many people consider the open ocean to be an example of a commons because _______.

Accepted Answer

The international fishery in the open ocean is an example of a commons, as it is a shared resource that is not owned or regulated by any specific country or entity. This can lead to issues of overfishing and depletion of fish stocks, as well as conflicts between countries over access to the resource. Therefore, management and regulation of the open ocean and its resources is crucial to ensure its sustainability.

Question 4

What is the tragedy of the commons? How do fishing technology and the tragedy of the commons intersect to jeopardize global fisheries?

Accepted Answer

The answer of What is the tragedy of the commons?...

Question 5

The tragedy of the commons states that any resource to which a group of people have free access is likely to become ______ and degraded as each seeks to ______ personal benefit without consideration for the needs of others.

Accepted Answer

The tragedy of the commons states that individuals will overexploit a resource when they have free access to it, in order to maximize their own personal benefit without consideration for others. Therefore, option B, "overexploited; maximize", best fits the definition of the tragedy of the commons. Options A and C are incorrect because they describe outcomes that are the opposite of what is typically seen in the tragedy of the commons. Option D is also incorrect because the tragedy of the commons typically results in overexploitation rather than underexploitation. Option E is incorrect because it does not accurately reflect the tragedy of the commons.

Question 6

Major issues associated with the fishing technique of bottom trawling include ________.

Accepted Answer

Bottom trawling has significant negative impacts on marine ecosystems, including bycatch of non-target species, damage to the seabed, and disturbance of the sediment plume, leading to ecosystem damage as a whole. Therefore, option E, all of these answers, is the correct answer.

Question 7

Fisheries have historically harvested apex predators and fish from high trophic levels.

Accepted Answer

Fisheries have historically targeted apex predators and fish from higher trophic levels, such as tuna, swordfish, and sharks, due to their high commercial value and large size. This has led to declines in these species and disruptions in their ecosystems.

Question 8

Many marine species are accidentally caught and killed in nets. Which of the following marine species' populations have been reduced as a result of bycatch from fishing?

Accepted Answer

Dolphins, sea turtles, and sea birds are all species that have been known to be caught and killed in fishing nets. The accidental capture of these species, known as bycatch, can have a significant impact on their populations.

Question 9

What is likely to be the MOST important global impact of bycatch?

Accepted Answer

Bycatch is a major threat to ocean biodiversity as it results in the unintentional killing and injuring of non-target species such as marine mammals, sea turtles, and sharks. This can have cascading effects on the ecosystem as the loss of one species can impact the entire food chain, leading to a decrease in biodiversity and potential collapse of entire ecosystems.

Question 10

What role do fish play in human diets? What drives consumption of fish in poorer and wealthier countries?

Accepted Answer

The answer of What role do fish play in human...

Question 11

One of the most serious threats to many marine species is the accidental capture of bycatch. Describe some ways to lessen the impact of bycatch on marine populations.

Accepted Answer

The answer of One of the most serious threats to...

Question 12

About 28.8% of the global fish stock is considered overfished. The reason fisheries have experienced such pressure is because __________.

Accepted Answer

All three reasons (A, B, and C) have contributed to the overfishing of fisheries. The growing human population has created a greater demand for protein, leading to overfishing. Technological advances have allowed us to fish much more efficiently, leading to the removal of every single fish from an area. In addition, resources in the open ocean are more susceptible to overuse and degradation, as there is no legal entity to lay claim to these resources.

Question 13

Nontarget species that become trapped in fishing nets and are usually discarded are known as __________.

Accepted Answer

Nontarget species that become trapped in fishing nets and are usually discarded are known as bycatch.

Question 14

The collapse of fish populations is caused by many different factors. Which of the following technological advances aided in this collapse?

Accepted Answer

All of these technological advances have contributed to the collapse of fish populations. Steam engines allowed ships to travel further and fish longer, flash freezing enabled the long-term storage of fish, trawler ships increased the efficiency of catching fish, and huge nets allowed for the capture of vast quantities of fish at once.

Question 15

In 1992, the United States banned the practice of _______ to catch fish.

Accepted Answer

The practice of drift netting was banned by the United States in 1992 as it caused a high amount of bycatch and resulted in the death of many marine animals including dolphins, whales, and sea turtles.

Question 16

Overfishing of upper-trophic-level fish has led to humans seeking new species to harvest at lower trophic levels. This is called:

Accepted Answer

Overfishing of upper-trophic-level fish has led to humans seeking new species to harvest at lower trophic levels, which is known as fishing down the food chain. This reduces the biomass of high-trophic-level species, alters food webs, and affects the overall ecosystem health.

Question 17

Overfishing decimated the cod fisheries in North America. How can this information be used to educate other North American fisheries to prevent the same thing from happening?

Accepted Answer

The answer of Overfishing decimated the cod fisheries in North...

Question 18

Which statement about fish is FALSE?

Accepted Answer

Fish consumption globally is actually higher than that of beef, indicating that the statement C is false. Fish is a significant source of protein worldwide, especially in coastal and riverine communities.

Question 19

Fishing from lower trophic levels helps the recovery of overfished species in higher trophic levels.

Accepted Answer

The answer of  Fishing from lower trophic levels helps...

Question 20

In Frenchman Bay, Maine, the objective of David Alves' program is to "turn fishers into fish farmers." What does this mean, and why does he call this the "future of fishing"?

Accepted Answer

The answer of In Frenchman Bay, Maine, the objective of...
