How to properly pick the periwinkle?
Shore fishing must be carried out in the respect of the natural environment and in the absence of degradation of the foreshore (a deliberate and significant alteration constitutes an offense). Periwinkle picking is usually done on rocks covered withalgae green or brown and under the pebbles partially submerged. There is thus two methods to collect periwinkles:
- Under the seaweed. Gently lift the plant to gently fold it to the side. Above all, do not tear them off. Underneath, sometimes hide a few gastropods clinging to the rock or to the algae themselves. Check whether specimens have fallen to the ground;
- Under the pebbles. When seeking shelter, periwinkles have two needs: space to crawl in and a small amount of water. When you observe these two criteria, lift the stone, take the gastropods of medium or large size and replace gently the pebble into place. While fishing, remember to wash and refresh the seashells in seawater.
