Technique d'élevage de deux palourdes comestibles (Tapes Decussatus L. et Tapes Pullastra Wood)

The clam is a shellfish whose flesh is highly appreciated and whose market value is quite high. The "true" clam Tapes decussatus and, to a lesser extent, Tapes pullustra WOOD, one of the "fake" clams, are the focus of an important trade. The clams, once immersed, stretch two membranous tubes, the siphons, out of the valves. This siphon can be twice as long as the animal itself. Tapes decussatus is identified thanks to the very neat canvas of its thick and solid shell, and by its two distinct siphons. The shell of Tapes pullastra has very fine striates. It is almost smooth, elongated, thick but fragile. The two siphons are attached over a large part of their length.
