Marine Protected Areas

Just like national parks protect land, Marine Protected Areas (MPAs) preserve underwater ecosystems. As of now, there are more than 6,500 MPAs, protecting about 2% of our oceans. There are different types of MPAs ranging from “Strict Nature Reserve” that allows no resource removal, to “Sustainable use of Natural Resources” where limited resources can be taken. Catalina Island has a whopping nine marine protected areas, both coastal and offshore. Some of them, like the Long Point State Marine Reserve is a strict “no-take” zone. However, the Bird Rock State Marine Reserve allows the removal of certain types of pelagic finfish.

Marine protected areas can benefit both the environment and the fishing economy. Protected species can grow larger, thus reproducing with higher success rate as well as reproducing more often. This means that as fish populate, some of them will venture out of the MPA. These potentially animals can be caught by fishermen in the area, leading to higher numbers caught, and larger animals caught.


We would like to thank you for visiting our blog. Catalina Island Marine Institute is a hands-on marine science program with an emphasis on ocean exploration. Our classes and activities are designed to inspire students toward future success in their academic and personal pursuits. This blog is intended to provide you with up-to-date news and information about our camp programs, as well as current science and ocean happenings. This blog has been created by our staff who have at least a Bachelors Degree usually in marine science or related subjects. We encourage you to also follow us on Facebook, Instagram, Google+, Twitter, and Vine to see even more of our interesting science and ocean information. Feel free to leave comments, questions, or share our blog with others. Please visit www.cimi.org for additional information. Happy Reading!
