How does climate change affect the distribution and abundance of marine fish species?

  1. It causes fish to migrate to new areas with more favorable conditions.

  2. It leads to an increase in the overall abundance of marine fish.

  3. It results in a decrease in the diversity of marine fish species.

  4. It has no significant impact on the distribution and abundance of marine fish.


Correct Option: A
Explanation:

Climate change is causing the oceans to warm, which is leading to changes in ocean currents and the distribution of marine species. Some fish species are moving to new areas with more favorable conditions, while others are experiencing population declines.

What is ocean acidification, and how does it affect marine fisheries?

  1. It is the process by which the pH of the ocean decreases, making it more acidic.

  2. It leads to an increase in the growth rate of marine fish.

  3. It results in a decrease in the abundance of marine phytoplankton.

  4. It has no significant impact on marine fisheries.


Correct Option: A
Explanation:

Ocean acidification is caused by the absorption of carbon dioxide from the atmosphere. It can have a negative impact on marine fisheries by making it more difficult for marine organisms to build and maintain their shells and skeletons.

How does sea level rise affect marine fisheries?

  1. It leads to an increase in the overall abundance of marine fish.

  2. It causes fish to migrate to new areas with more favorable conditions.

  3. It results in a decrease in the diversity of marine fish species.

  4. It has no significant impact on marine fisheries.


Correct Option: B
Explanation:

Sea level rise is causing coastal habitats to be inundated, which is forcing marine fish to migrate to new areas. This can lead to competition with other fish species and a decrease in the overall abundance of marine fish.

What are some of the economic consequences of climate change on marine fisheries?

  1. It can lead to a decrease in the value of commercial fisheries.

  2. It can result in job losses in the fishing industry.

  3. It can increase the cost of seafood for consumers.

  4. All of the above.


Correct Option: D
Explanation:

Climate change can have a negative impact on the economic viability of marine fisheries. This is due to a combination of factors, including changes in the distribution and abundance of marine fish species, ocean acidification, and sea level rise.

What are some of the potential adaptation strategies that can be used to mitigate the effects of climate change on marine fisheries?

  1. Developing new fishing methods that are less harmful to marine ecosystems.

  2. Establishing marine protected areas to protect critical fish habitats.

  3. Investing in research to develop new and more sustainable aquaculture techniques.

  4. All of the above.


Correct Option: D
Explanation:

There are a number of potential adaptation strategies that can be used to mitigate the effects of climate change on marine fisheries. These include developing new fishing methods that are less harmful to marine ecosystems, establishing marine protected areas to protect critical fish habitats, and investing in research to develop new and more sustainable aquaculture techniques.
