At the crossroads of art, activism, and the ocean lies the extraordinary story of Paolo Fanciuli, a humble Italian fisherman with a revolutionary vision. Known as Paolo the Fisherman, he has waged a quiet but fierce war against illegal bottom trawling - one of the most destructive fishing practices threatening marine ecosystems. Driven by years of witnessing the ocean's decline, Paolo devised a radical and poetic solution: the creation of an underwater museum—a surreal seabed installation of massive marble sculptures. These works of art serve a dual purpose: they physically block trawling nets from destroying the seafloor, and they symbolically stand as monuments to resistance and hope. HOUSE OF FISH is a conservation documentary that blends Paolo’s intimate, personal journey with a natural history perspective on the fragility of our oceans. HOUSE OF FISH is a cinematic ode to the sea and to those who dare to protect it through creativity and courage. By spotlighting Paolo’s efforts and the power of artistic activism, the film aims to awaken a deep emotional connection to our oceans - and inspire urgent action to save them.
