The common cockle is (as its name says) a common shell in Europe. This species is of commercial interest in several countries (like in Great Brittan and Holland).
A couple of years ago mechanical harvesting was banned in Holland due to damages the vessels and the gear caused to the bottom fauna. The cockles are therefore now harvested manually.
We have cockles in Norway as well, but we do not have those large harvesting areas like the shallow banks off the coast of Holland.
The cockles above were found on sand bottom (30 cm. depth). I used my fingers to filter the sand, and it was then easy to find (and feel) the cockles. The growth lines indicate that these cockles are 5-8 years old.
The Norwegian name for common cockle is “heart shell” (translated). When you look at the photo of a live cockle below you will understand how it got its Norwegian name.
