Extreme heat causes mass shellfish mortality in Italian Adriatic aquaculture

Impact verdict

Low impact. Loss pathway is aquaculture stock mortality from a marine heatwave in the upper Adriatic. Public reporting cites roughly 1,000 quintals of dead mussels and up to 90% clam mortality, alongside an industry estimate of EUR 200 million in annual climate-related damages to Italian fisheries. No insured loss figure has been disclosed, and Italian aquaculture is typically covered by domestic insurers or self-insured cooperatives with limited international specialty market participation. A single-region environmental event without a credible route to USD 100m of insured loss remains LOW.
