MCP is dedicated to preserving and protecting coastal resources in the Philippines through education, volunteerism and research. They work to preserve fragile marine habitats like coral reefs and mangrove forests, with an additional aim of improving the quality of life for marginalised fisherfolk in the central Philippines. A volunteer based organisation, international volunteers can join a large professional team of marine biologists, scientists, teachers and dive instructors. Participation in the program involves extensive scuba diving activities, with training offered on site. ‘Since becoming operational in 2015, MCP has led mangrove replantation efforts, and have removed tons of marine debris and ghost nets. Volunteer divers have placed sinkers and buoys in many marine protected areas, improving demarcation and local conservation efforts, whilst volunteers have taught numerous school classes in the municipality about marine issues.’ Their YouTube channel is https://www.youtube.com/c/MarineConservationPhilippines Amongst several others, check out their video about conservation volunteering at https://www.youtube.com/watch?v=qA6hggVddfs

The Marine Fish Conservation Network is a US coalition of commercial and recreational fishing associations, regional and national conservation groups, aquaria, and marine science organizations committed to sustaining fish populations, healthy marine ecosystems, and fishing communities. Their goal is to maintain and strengthen the conservation and management objectives of the Magnuson-Stevens Fishery Conservation and Management Act.

The Marine Institute (Foras na Mara) is the Irish national agency responsible for Marine Research, Technology Development and Innovation (RTDI)

In 2019 Marine Stewards initially focused on sustainable fishing practices in Singapore, and has since expanded its marine conservation programme to encompass Biodiversity, Habitats and Pollution threats to their ocean. They are now represented at engagement sessions with various government agencies.. Their citizen science programme has had several successes, including uncovering illegal sales of the critically endangered shovelnose ray in local wet markets. Their current activities include coral husbandry, reef surveys and monitoring, and responsible fishing.

MSC sets a standard for sustainable fishing. Fisheries that wish to demonstrate they are well-managed and sustainable compared to the science-based MSC standard are assessed by a team of experts who are independent of both the fishery and the MSC. Seafood products can display the blue MSC ecolabel only if that seafood can be traced back through the supply chain to a fishery that has been certified against the MSC standard. Founded by the World Wide Fund for Nature

Marine Watchdogs focuses on the health of the ocean and the food products that come from it. A member-based nonprofit action company, their mission includes research, education and active projects like seafloor cleanup events. They aim to engage the public and enable ways for people to get involved in ocean ecology via seabed survey and seafloor clean-ups. Their multiple activities include: conducting toxicology tests, alerting the public to contamination issues, conducting marine bio fieldtrips, providing educational resources, and running campaigns aimed at reducing single-use plastic waste and agricultural chemical run-off.

Mwambao’s mission is facilitating a network linking coastal communities and other partner stakeholders that builds community resilience and improved sustainable coastal resource management and livelihoods. The network currently has eight member villages located in Unguja, Pemba, Tanga, Bagamoyo and Temeke Districts. Given the extensive marine resources in the area, attention is given to understanding the coastal marine ecosystems, improving fisheries management (with octopus an important catch) and an informed awareness of their natural resources in order to protect them in a sustainable manner. They have adopted Reef Ball technology to restore their coral reefs.

NAMMCO is an international regional body for cooperation on the conservation, management and study of marine mammals in the North Atlantic. The four partners are Faroe Islands, Greenland, Iceland and Norway. They have the aim of 'sustainable and responsible utilisation of all living marine resources, including marine mammals.' Through their cooperation under the umbrella NAMMCO, they 'aim to strengthen and further develop effective conservation and management measures for marine mammals'.

The mission of the NFCC is to protect healthy oceans and fisheries through collaborative problem-solving, thus to maintain the ocean's capacity to sustain abundant, healthy fisheries and ecosystems. They link people who depend on the oceans with experts in science, policy, and business to develop solutions that last. Their largest program, Global Ocean Health, concentrates on carbon pollution and its multiple consequences to healthy seas and coastal communities.

A network of Caribbean environmental organisations, developing strategies in the following areas: Biodiversity conservation, Ecosystem-based approaches to climate change adaptation, Regional environmental governance, Sustainable livelihoods

NAMA is a fishermen-led organization working at the intersection of marine conservation and social, economic, environmental justice, 'working to build a movement toward a healthy ocean and a just seafood system.'

The Organization for the Conservation of Cetaceans (OCC) in Uruguay works for the conservation of the marine ecosystem as well as the environment of the coastal communities, thus integrating ecological, socio-cultural and economic perspectives. They focus on marine conservation environmental education and awareness, responsible marine tourism, sustainable fishing and the creation of offshore MPAs.
