Concrete anti-trawling devices are low-cost and effective

Anti-trawling devices are specialized tools or structures designed to deter or block trawling activities in specific areas of the ocean. These devices help protect sensitive marine ecosystems, such as coral reefs and seagrass beds, from the destructive impact of trawling nets, which can damage habitats and lead to overfishing. By enforcing sustainable fishing practices, anti-trawling devices contribute to marine conservation and biodiversity preservation. Additionally, these devices provide a substrate for various marine organisms, such as oysters and mussels, creating new opportunities for local fishers.

Depending on their size, anti-trawling devices cost just $55 to $140 to make.

Anti-trawling devices in Cambodia

Our partner, Marine Conservation Cambodia (MCC), is making remarkable strides in protecting marine ecosystems through the deployment of conservation and anti-trawling structures (CANTS). To date, MCC has successfully deployed 270 CANTS in Cambodian waters, safeguarding the Kep Marine Fisheries Management Area and vital habitats for endangered species like the Irrawaddy dolphin. MCC’s success has also inspired similar efforts in neighboring Kampot province, where they collaborated with Wild Earth Allies and local fishing communities to expand the use of CANTS, benefiting rich marine life and supporting sustainable livelihoods.
