The UK's first fully protected marine reserve is already providing positive results for both fishermen and conservationists after only two years in operation. The reserve has seen a significant increase in commercially valuable scallops and several species of algae promoting biodiversity.
Marine ecologists at Oregon State University have shown that tiny fish larvae can drift with ocean currents and replenish fished areas long distances. This discovery adds credibility to the effectiveness of marine reserves in rebuilding fishery stocks, providing a significant demonstration of their ability to sustain fisheries beyond t...
Mandy Karnauskas, a Ph.D. student at the Rosenstiel School of Marine & Atmospheric Science, won the best student poster award for her research on marine reserves in Belize to understand why fishers and scientists often have different perceptions of change in fish abundance around these areas.
Scientists need to be more proactive and effective in communicating their research findings to various audiences, including resource users, communities, and the general public. A comprehensive approach to communication used in the establishment of marine reserves can be applied to other areas of science and natural resource management.
A comprehensive study found that community involvement is crucial for the success of marine reserves. Residents' compliance with reserve rules was linked to ecological health and fish stocks. Community participation in setting up and monitoring reserves is vital to their success.
A special issue of PNAS explores the latest science on marine reserves, revealing that well-designed reserves can benefit both fish and fishermen. Studies show that reserves can play a major role in reducing cumulative impacts on marine ecosystems in areas like the South China Sea and Coral Triangle.
A recent study found that successful marine reserves had a positive impact on fish stocks, with human population pressure being a critical factor. Local involvement in research and management, as well as social, political, and economic factors, were also key to making reserves successful.
Researchers found that marine reserves replenish harvested species outside the reserve, producing larger fish and more plentiful populations. The establishment of reserves also supports larval production, benefiting fished populations.
Recent study reveals coral species tend to stay close to home, with high local genetic diversity important for conservation. Marine reserves should prioritize locally sourced coral recruitment to maintain healthy populations.
The study revealed 57 coral species, with higher diversity in smaller patchy areas and a focus on protecting larger conservation units. The authors recommend marine reserves to protect high-biodiversity areas, such as the islands of Isla Galera, Isla San Telmo, and Isla Mogo Mogo.
A new global map tracks human influences on marine ecosystems, revealing that coral reefs are in trouble and few blue spots on the planet are pristine. The study suggests that about 41% of oceans bear a serious human footprint, with areas like the North Sea and Caribbean Sea showing deepest impacts.
A study published in Proceedings of the National Academy of Sciences found that marine reserves can double the number of young corals, leading to a healthier reef ecosystem. The Bahamas' Exuma Cays Land and Sea Park was used as a testing ground for this innovative approach.

The study aims to improve our understanding of species movement and habitat requirements, enabling more efficient design and assessment of future marine-protected areas.
A study in Science journal reveals that marine reserves can support the growth of parrotfish populations, maintaining reef ecosystems. The Nassau Grouper's impact on the reef is minimal due to the size limit for predation, enabling healthy coral reef recovery.
The Madison/Swanson and Steamboat Lumps marine reserves in the Gulf of Mexico have been given a new life after a two-year extension. Larger fish with greater egg-producing potential were found within the protected sites than outside them, indicating the reserves are working as designed.
The Eastern Tropical Pacific Seascape initiative protects 211 million hectares of marine habitat, including nesting grounds for the critically endangered leatherback turtle. The project addresses mounting evidence that the ocean is under duress, with 90% of large predatory fish populations and 75% of commercial fish populations at risk.
