The International Collective in Support of Fishworkers (ICSF) is a dedicated non-governmental organization focused on promoting equitable, gender-just, self-reliant, and sustainable fisheries, particularly in the small-scale artisanal sector. Founded in 1984 during the International Conference of Fishworkers and their Supporters in Rome, ICSF aims to enhance the recognition and rights of fishworkers and fishing communities on national, regional, and international platforms.

ICSF's mission is to empower these communities and organizations through a human rights-based approach, ensuring participation in fisheries that prioritizes decent work, equity, and sustainability. With a robust history of advocacy, ICSF addresses various critical topics including the rights of small-scale fishworkers, marine protected areas, gender issues in fisheries, and labor rights. The organization collaborates with fishworker groups and like-minded organizations to support capacity building and sustainable resource management. As of 2017, ICSF operates from Amsterdam, Netherlands, continuing its vital mission to secure the livelihoods and dignity of fishing communities worldwide.
