Stone tidal weirs are a type of fish barrier operated by tidal amplitude.  These structures are made of large rocks, extending along the shoreline on a colossal scale in semicircular, arrow-like, or almost linear shape. These weirs are completely submerged during high tide, and they emerge into full view at low tide, allowing people collect fish.

They are located within seascapes created and maintained by the harmonious interactions between humans and marine ecosystems.  Although they are on the verge of disappearance because of costal developments and global climate change, their role as eco-friendly fishing gear, womb for sustaining marine biodiversity, and tourist attraction has started attracting international attention.

This solution focuses on the cooperation established by universities and coastal communities to raise awareness on the role of stone tidal weirs and the connected traditional ecological knowledge of coastal communities as the cultural heritage.
