Italian fishermen turn to export market as invasive blue crab eradication efforts stall

After government-funded culling failed to control the predator, Po River Delta cooperatives are shipping blue crabs to Sri Lanka for processing.

The short version

  • Italian fishing cooperatives in the Po River Delta have halted crab incineration and are now exporting catches abroad via a joint venture with a Sri Lankan seafood processor.
  • The invasive Atlantic blue crab explosion decimated local Manila clam stocks, leading to a 75% drop in cooperative revenue across 2024 and 2025.
  • The Italian government shelved its official eradication program after catching and destroying nearly 2.3 million kilograms of crab failed to slow reproduction.
  • Efforts are ongoing to build domestic consumer demand and test biological controls, though broad market adoption in Italy remains limited.

Key facts

  • The Polesine Fishermen’s Cooperative Consortium saw revenues plunge 75% to 15 million euros in 2024 and 2025 as active members decreased from 1,500 to 850 due to the crab invasion.[Associated Press]
  • The Italian government abandoned its blue crab eradication program after subsidizing the culling and incineration of nearly 2.3 million kilograms of crabs across two years without substantially curbing population growth.[Associated Press]
  • Under a joint venture with Sri Lanka's Taprobane Seafoods, the Scardovari cooperative steams, freezes, and ships crabs to Sri Lanka for hand-processing, projecting 20 million euros in revenue for the current year.[Associated Press]
  • Blue crabs sell for roughly 1.30 euros per kilogram, compared with 10 euros per kilogram for Manila clams, which historically provided 90% of local fishermen's revenue.[Associated Press]
  • University of Bologna researchers released 150,000 juvenile octopuses into the Adriatic Sea in an experimental attempt to test natural predation on the crab population.[Associated Press]

What remains uncertain

  • Scientists and fishermen question whether releasing octopuses will effectively limit crab numbers, given high expected juvenile octopus mortality and mismatched habitat preferences.[Associated Press]
  • It remains uncertain whether domestic Italian restaurant and retail demand will expand sufficiently to support local fisheries, amid continuing culinary resistance and labor constraints.[Associated Press]
