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.

MedReAct’s mission is 'to catalyse action for the recovery of Mediterranean marine ecosystems by ensuring a fair and responsible long-term use of our Common Sea.' MedReAct consists senior marine campaigners and NGOs that jointly worked to reform of the Common Fisheries Policy (CFP), and who coordinated the coalition OCEAN2012 in Greece, Cyprus, France, Italy and Spain (ocean2012.eu), which helped securing the CFP main objective of stopping overfishing by 2020. They have now turned their attention to recovery of the Mediterranean ecosystems.

OBIS is a global open-access data and information clearing-house on marine biodiversity for science, conservation and sustainable development. As a project of the International Oceanographic Data and Information Exchange programme of UNESCO’s Intergovernmental Oceanographic Commission, it aims to be 'the most comprehensive gateway to the world’s ocean biodiversity and biogeographic data and information required to address pressing coastal and world ocean concerns. It has the mission to be global alliance in which scientists share biodiversity and biogeographic data and information on marine life. There are more than 30 OBIS nodes around the world connect 500 institutions from 56 countries.

Our Fish is working to end overfishing and restore a healthy ocean ecosystem. By collaborating with others, and deploying robust evidence, they are calling for an end to overfishing as a critical and significant action to address the biodiversity and climate crisis.

Pescadolus is a platform promoting inter-disciplinary international research to better understand the complexities of fisheries crime towards law and policy reform.

Pew Charitable Trust’s ocean work includes efforts to create large marine reserves; end illegal fishing; protect key species such as penguins, sharks, tuna and forage fish; and establish policies that protect, maintain, and restore the health of marine ecosystems.

Reef Environmental Education Foundation (REEF) is an international marine conservation organization that implements hands-on programs to involve local communities in conservation-focused activities. REEF is based in Key Largo, Florida, with remote staff in Illinois, California, and Washington. Its mission is to protect biodiversity and ocean life by actively engaging and inspiring the public through citizen science, education, and partnerships with the scientific community.
REEF's work focuses on four main projects: the Volunteer Fish Survey Project, the Grouper Moon Project, the Invasive Species Program, and the Explorers Education Program. REEF's marine conservation and citizen science programs currently operate in the coastal areas of North and Central America, the Caribbean, Eastern Atlantic and Mediterranean, Hawaii, the South and Indo-west Pacific, Indian Ocean, and Red Sea.

Fish spawning aggregations are significant events that support many fisheries globally. SCRFA’s mission is to support and promote the stewardship of these events through science-based conservation and management. Their website provides information explaining the importance of aggregations for fishes, fisheries and ecosystems, and information about aggregating species. They maintain a database which contains over 1,000 fish aggregation records from around the world. It holds extensive information on spatial and temporal characteristics and the current status according published and unpublished literature, natural history accounts, anecdotal information (including interview) and field research. The database establishes a basis for planning, education and research, and for identifying conservation and management needs.

Seychelles Seatizens is a fish identification website and database. Founded by an experienced conservationist, it is intended to support a wide cross-section of stakeholders and enhance their understanding, awareness and appreciation of the Seychelles marine environment, including the fishing industry and its sustainability via improving fishery monitoring and co-management, and marine researchers, amongst others.

The Smithsonian Tropical Research Institute in Panama aims to increase understanding of the past, present and future of tropical biodiversity and its relevance to human welfare. More than 1,400 scientists from around the world every year collaborate on hundreds of projects at remote field sites and in their laboratories in Panama City. In addition to the research, they have a strong outreach programmes at several sites in Panama, educating visitors on marine and coastal ecosystems, marine life, mangroves, and fisheries and marine conservation, amongst others. In terms of resources, they maintain several databases on their website which record the biodiversity of the area.

SAIAB serves as a major scientific resource for knowledge and understanding the biodiversity and functioning of globally significant aquatic ecosystems. SAIAB’s science focuses on the full spectrum of aquatic environments: from marine offshore to continental freshwater catchments. Research covers ecology and conservation biology that links biodiversity at molecular and organism levels with the environment and genetic and species diversity.

Tuzly Lagoons National Nature Park is a Protected area located in Bilhorod-Dnistrovskyi Raion of Odessa Oblast, southern Ukraine. The park was set up in 2010. Also known as Tuzlovski Lagoons National Park. The lagoons are separated from the Black Sea by a 29-km long sandbar, which is 60–400 m wide and 1–3 m high. Every spring for the past 30 years, conservationists at the Tuzly Lagoons national park on the Black Sea in Ukraine have been digging shallow channels from the coastal lagoons down to the shoreline, linking the bodies of water together. The rivulets, which used to occur naturally until industrial agriculture plugged the small rivers that fed them, are a busy through-route for billions of small fish, which winter in the sea then return to the lagoons to breed.
