Marine living resources encompass all life forms found within the world's seas and oceans. They represent the vital biological component of these vast aquatic environments.
Defining Marine Living Resources
According to the provided reference, marine living resources are defined comprehensively:
- They are all organisms in the seas and oceans.
- Their size range is immense, from microscopic bacteria to giant fish and mammals.
- They constitute the biological component of our oceans.
- Specifically, this definition also includes all of the organisms that are utilized by humans, such as for harvesting or recreational uses.
Essentially, if it's alive and lives in the sea or ocean, it's considered a marine living resource. This includes everything from the smallest microbes crucial for nutrient cycles to the largest whales and valuable fish species.
Scope and Examples
The scope of marine living resources is incredibly broad. Here are some examples categorized for clarity:
- Microscopic Life:
- Bacteria

- Zooplankton (microscopic animals)
- Invertebrates:
- Corals
- Shellfish (clams, oysters, mussels)
- Crustaceans (crabs, lobsters, shrimp)
- Jellyfish
