The Po Delta's clam farming industry is in crisis due to the combined effects of high prices driving consumption down, water quality issues causing a 35% loss of molluscs, and the threat of increased imports due to decreased domestic production. The sector, which is concentrated among 1500 companies, is seeking government aid and funding for hydraulic infrastructure to mitigate the impacts of climate change on the lagoons. The industry faces challenges such as high temperatures, reduced river flow, and toxic algae blooms, which are leading to concerns about the sustainability of Italian aquaculture and the quality of seafood available to consumers.
