Marmorkrebs found in Sweden, again

Apologies for being a bit behind the curve on this one, but I just saw the latest press release from back in July from the Swedish Agency for Marine and Water Management saying that Marmorkrebs had been found again this last summer, and in a different location that last autumn, and multiple individuals of different sizes.

This is not good news for Sweden, as it suggests Marmorkrebs are gaining a beachhead in that country.


Long overdue update, 30 June 2022: It wasn’t Marmorkrebs at all. It was still invasive, but a signal crayfish. It may have been a “mottled” colour pattern described here. The map is being updated.
