Den asiatiska blåskrabban har återigen siktats på Västkusten. Krabban hotar de inhemska arterna då de snabbt tar över ekosystemen och den som hittar en blåskrabba uppmanas att döda den.

Den ovanliga krabban sågs senast i Ljungskile, rapporterar P4 Väst. Blåskrabban är ganska liten, med en ryggsköld som är högst fyra centimeter bred med en hudblåsa i ”tumvecket” mellan hanens klor och tvärrandiga ben.

Den äter nästan allt i sin väg under 90 procent av sin aktiva tid. Tillsammans med penselkrabban hotar blåskrabban våra hav enligt Erland Lettevall, utredare på miljöövervakningsenheten vid Havs- och vattenmyndigheten.
