Ocean zones with restrictions on fishing and development that let ecosystems recover.
Fully protected 'no-take' reserves show increased biomass and spillover to nearby fisheries. Only about 3 percent of the ocean is fully or highly protected.
Benefits increase with size, age and enforcement. Networks of MPAs support connectivity. Community involvement improves compliance.
Example: Great Barrier Reef zoning protects part of the reef from fishing.

Marine Protected Areas is one of the 54 topics in Marine & Environmental Biology. It is rated Intermediate, so it suits learners who already know the core vocabulary. Related topics in this area include Coral Reefs, Fisheries Management, Marine Food Webs.
Cabo Pulmo in Mexico saw fish biomass increase about 460 percent.
Work through the Beginner topics in Marine & Environmental Biology first, such as Oceans, Ocean Zones, Plankton, then return to Marine Protected Areas. Intermediate topics assume the Beginner vocabulary.
The closest topics to Marine Protected Areas are Coral Reefs, Fisheries Management, Marine Food Webs, Upwelling. Comparing them side by side is a good way to see how the ideas connect.
Read the summary and the in-depth section, then use the quick check on the interactive lesson for Marine Protected Areas. To practise the whole of Marine & Environmental Biology, use the Marine & Environmental Biology quiz.
Marine Protected Areas: Ocean zones with restrictions on fishing and development that let ecosystems recover. Coral Reefs: Biodiverse ecosystems built by coral polyps living in partnership with symbiotic algae. Read both side by side and note what each one explains.
First, read the summary and write the definition in your own words. Second, read the in-depth section and note any example. Third, compare it with Coral Reefs and explain the difference aloud. Finally, take the Marine & Environmental Biology quiz and come back to this page for any question you miss.
