Exhibition and excursion of the CREPAN in Vierville CREPAN, a regional committee for the study, protection and development of nature in Lower Normandy, organized an information day in Vierville-sur-Mer on a Sunday. The morning exhibition, installed in the communal hall, however, received too few visitors. Signs showed the coastline, the different types of puddles, their fish, algae and the inhabitants of the sand and rocks. A low tide excursion followed in the afternoon. On their return, the participants built an aquarium with the few samples collected, in order to observe the functioning of the mussels. The goal was to raise public awareness of its environment, here in the marine environment. A new day of the same type was announced for the following month. The organizers recalled that these appointments were open to all. Archive image: https://vierville.cordelle.eu/PhDoc10/1982Juil20-CREPAN.jpg
