A new invading sea crab reaches the Ebro Delta
Date:5/25/2012

s aestuarii, the native crab species very abundant in the Ebro Delta. They also appeared in the bay of Els Alfacs amongst the catches of small-scale fisherman from Sant Carles de la Rpita (Tarragona).

A potential danger for the native fauna

"Dyspanopeus sayi is a species that can withstand temperature and salinity changes very well. It can therefore colonise shallow coastal areas (as shallow as 46 metres) and, more specifically, estuaries," explains the biologist from IRTA. It does not live in fresh water. Therefore, in the Ebro Delta they have only been found in the bay of Els Alfacs and it has not yet been confirmed whether they are present in the bay of Fangar.

This species of sea crab has a marked sexual dimorphism: the males are bigger than the females. The crabs feed on bivalve molluscs like mussels and clams and they use their strong claws to break shells. As predators they hunt at dusk or in the darkness.

Up until now the researchers have not detected any significant effect on the native fauna of the bay of Els Alfacs but monitoring with regular sampling in the area has not yet been carried out to confirm this.

However, as Guerao states, "considering their diet (bivalve molluscs) and the effect that this species has had in other places (in the Adriatic Sea it has exterminated some species like the Mytilus galloprovincialis mussel and the Ostrea edulis oyster) it would be interesting to regularly monitor the dynamic of Dyspanopeus sayi in the Ebro Delta."
