Understanding the Importance of Marine Ecosystems and Fisheries Management
Fisherfolk are individuals or communities who depend on fishing and other aquatic resources for their livelihoods. They may be small-scale, artisanal fishers, or they may work in larger commercial fishing operations. Fisherfolk often have a deep understanding of the ocean and its rhythms, and they play an important role in preserving traditional knowledge and practices related to fishing and marine resource management.
18. What is the purpose of the FAO's work on small-scale fisheries ?
The Food and Agriculture Organization (FAO) of the United Nations works to support the development and sustainability of small-scale fisheries around the world. The organization recognizes the importance of these fisheries for food security, poverty reduction, and the well-being of coastal communities. FAO's work in this area includes providing technical assistance, promoting policy and regulatory reforms, and raising awareness about the value of small-scale fisheries.
19. What is the difference between a fishery and a fishing ground ?
A fishery refers to the total catch of fish and other seafood resources from a particular area or fishery management zone. A fishing ground, on the other hand, is a specific location where fishers go to catch fish. Fishing grounds can be within a larger fishery, but not all fisheries have defined fishing grounds.
20. What is the purpose of a fishery management plan ?
A fishery management plan is a document that outlines how a fishery will be managed and regulated. The purpose of a fishery management plan is to ensure the long-term sustainability of the fishery, while also considering social and economic factors. A well-managed fishery can provide a stable source of income for fishers, while also maintaining healthy fish populations and protecting the marine environment.
21. What is the difference between a trawler and a longliner ?
A trawler is a type of fishing vessel that uses a trawl net to catch fish. A longliner, on the other hand, is a fishing vessel that uses a longline to catch fish. Trawlers are typically used in shallower waters, while longliners are often used in deeper waters.
22. What is bycatch, and why is it a concern ?
Bycatch is the term used to describe the catch of non-target species or undersized fish that are caught accidentally during commercial fishing operations. Bycatch can include a wide range of marine animals, from endangered species like sea turtles and dolphins to commercially valuable fish like sharks and rays. Bycatch is a concern because it can deplete non-target species populations, harm the marine ecosystem, and reduce the profitability of fishing operations.
23. What is the purpose of a marine protected area (MPA) ?
A marine protected area (MPA) is a designated area of ocean or coastal habitat that is protected from human activities that could harm the environment or the species that live there. The purpose of an MPA can vary, but some common goals include protecting endangered species, preserving biodiversity, and maintaining healthy fish populations. MPAs can also help to support sustainable fishing practices and promote eco-tourism.
24. What is the difference between a coral reef and a coral atoll ?
A coral reef is a ridge of rock or coral that runs along a coastline, often with a lagoon in the center. A coral atoll, on the other hand, is a ring-shaped reef that surrounds a lagoon. Coral atolls are formed when a volcanic island subsides, leaving only the coral reef exposed.
25. What is ocean acidification, and why is it a concern ?
Ocean acidification is the decrease in the pH of the ocean due to the absorption of carbon dioxide from the atmosphere. This increase in acidity can have negative impacts on marine organisms, particularly those with calcium carbonate shells like corals and shellfish. Ocean acidification is a concern because it can lead to the degradation of marine ecosystems and the loss of biodiversity.
26. What is the difference between a sea turtle and a land turtle ?
Sea turtles are reptiles that live in the ocean and only come onto land to nest. Land turtles, on the other hand, are reptiles that live on land and do not spend much time in water. Sea turtles have flippers instead of legs and are well-adapted to life in the water, while land turtles have legs and are better suited to life on land.
27. What is a marine mammal, and why are they important ?
A marine mammal is any mammal that lives in the ocean or coastal areas. Examples of marine mammals include whales, dolphins, seals, and sea lions. Marine mammals are important because they play a key role in maintaining the balance of their ecosystems and providing food and other resources for human communities.
28. What is the difference between a fish farm and a wild fishery ?
A fish farm is an aquaculture operation that raises fish in captivity for food or other purposes. A wild fishery, on the other hand, is a fishery that catches fish from wild populations in the ocean or other bodies of water. The main difference between these two is that fish farms are controlled environments, while wild fisheries are subject to the natural variability of the environment and the species they target.
29. What is the purpose of an international marine agreement ?
An international marine agreement is a treaty or other type of agreement between countries that aims to protect the marine environment and promote sustainable use of marine resources. The purpose of an international marine agreement can vary, but some common goals include establishing marine protected areas, regulating fishing practices, and addressing issues like pollution and climate change.
30. What is the difference between a coastal ecosystem and a coral reef ecosystem ?
A coastal ecosystem is a community of plants and animals that live in the area where the land meets the sea. A coral reef ecosystem, on the other hand, is a community of plants and animals that live on or near coral reefs. Coastal ecosystems can include mangroves, salt marshes, and seagrass beds, while coral reef ecosystems are characterized by the presence of coral and the many species that depend on it.
