REXCOR – a lobster sheltered in the artificial reefs!

News - 07 August 2018
The spiny lobsters and small lobsters recently observed in the artificial reefs of REXCOR are not the only macrocrustaceans to have chosen to shelter within the multiple anfractuosities recently created by SEABOOST in the impacted areas of the Calanques National Park (Mediterranean Sea, France). In fact, scientific divers from Andromeda Oceanology observed this summer a European lobster (Homarus gammarus).

This species, which has become rare in the Mediterranean, is generally found in depths from 30 m depth and more. Sciaphile and nocturnal, the European lobster usually leaves its hole at night to hunt. During the day, it particularly likes narrow crevices that allow to keep the contact of the upper part of his carapace with the rock and the lower part with the soft sediment that he constantly remodels with its two different claws. It also chooses anfractuosities with a loophole allowing to escape in case of attack. The crevices chosen are also privileged places for reproduction and protection during the many moulting phases that punctuate the life cycle of the European lobster.

Encouraging first observations that the scientific follow-up will support over the next three years. Note that this is the second observation of the installation of a European lobster in the lower part of a Ragues © type reef, the first having been carried out in the Protected Marine Area of ​​Cape Town. Agde in 2009.
