Ocean and Fisheries

What are the different types of ocean ecosystems?

• mountain ranges, deserts, grasslands

• freshwater lakes, rivers, ponds

• open ocean, coral reefs, kelp forests, estuaries, deep sea

• tropical rainforests, tundra, savannahs

What is marine biodiversity?

• The variety of life forms and ecosystems found in the ocean and other marine environments.

• The variety of life forms and ecosystems found in terrestrial environments.

• The variety of life forms and ecosystems found in freshwater environments.

• The study of marine life forms and ecosystems.

How does overfishing impact marine ecosystems?

• Overfishing has no impact on marine ecosystems.

• Overfishing increases fish populations and improves the food chain in marine ecosystems.

• Overfishing has a positive impact on habitats and promotes balance in the ecosystem.

• Overfishing depletes fish populations, disrupts the food chain, damages habitats, and causes imbalances in the ecosystem.

What is sustainable fisheries management?

• The practice of ignoring regulations and quotas for fishing activities.

• The practice of managing fish populations and their habitats in a sustainable manner.

• The practice of using harmful fishing methods that damage marine ecosystems.

• The practice of overfishing and depleting fish populations.

What are marine protected areas?

• Designated areas in the ocean that are managed to conserve and protect marine ecosystems, habitats, and species.

• Places where marine animals are kept in captivity

• Areas in the ocean where fishing is allowed

• Locations where marine pollution is allowed

Name one type of ocean ecosystem and describe its characteristics.

• Coral reefs

• Tundra

• Kelp forests

• Mangrove swamps

Why is marine biodiversity important for the environment?

• Marine biodiversity has no impact on the environment.

• Marine biodiversity is important for the environment because it supports ecosystem stability, provides food and resources, and contributes to climate regulation.

• Marine biodiversity actually harms the environment.

• Marine biodiversity only benefits humans, not the environment.

What are the main causes of overfishing?

• Excessive fishing effort, lack of effective fisheries management, illegal and unregulated fishing practices, and destructive fishing methods.

• Overpopulation, lack of fish breeding, and government regulations

• Decreased demand for fish, lack of fishing technology, and limited fishing areas

• Climate change, pollution, and natural disasters

Explain the concept of maximum sustainable yield in fisheries management.

• Maximum sustainable yield is the total amount of fish that can be harvested from a population without any impact on its ability to reproduce and replenish itself.

• Maximum sustainable yield is the minimum amount of fish that can be harvested from a population without depleting its ability to reproduce and replenish itself.

• Maximum sustainable yield is the maximum amount of fish that can be harvested from a population without depleting its ability to reproduce and replenish itself.

• Maximum sustainable yield is the maximum amount of fish that can be harvested from a population without any consideration for its ability to reproduce and replenish itself.

What are the benefits of establishing marine protected areas?

• Negatively impacting biodiversity, disrupting ecosystems, and limiting educational opportunities

• Limiting economic growth, reducing fishing opportunities, and hindering scientific research

• Conserving biodiversity, protecting habitats and ecosystems, promoting sustainable fishing practices, and supporting scientific research and education.

• Increasing pollution, promoting overfishing, and destroying habitats
