The accidental capture of cuttlefish eggs by Boulogne potters has initiated a promising research and development project. These eggs, collected by CRPMEM Hauts-de-France and incubated at Maréis, achieved a 75% survival rate post-hatching. This empirical experiment offers new insights into squid and cuttlefish, which were the most economically valuable species landed at Boulogne-sur-Mer in 2023, as reported by France AgriMer.
