The bivalve Macoma predominated in the diet early and late in the tidal cycle, while Nel-eis worms were the major prey over low water. Intake rate of Macoma did not change during the course of the tidal cycle, whereas the intake rate of Nereis markedly increased following emersion and decreased near to the end of the low water period.

Macoma balthica est une espèce typique des zones calmes (estuaires, baies profondes) comme par exemple la baie de Saint-Brieuc. L'espèce est dispersive : elle se rencontre sur de vastes surfaces. Adulte, elle vit enfouie sur le côté de préférence dans les cinq premiers centimètres des sédiments vaseux ou sableux fins recouverts de vase en zone intertidale*.

The present study examined larval settlement responses of the M. balthica rubra subspecies (further referred to as Macoma balthica… M. balthica is capable of deposit as well as suspension feeding (Brafield & Newell, 1961; Wolff, 1973; Fish & Fish, 1989). M. balthica is able to withstand low winter temperatures. In the Dutch Wadden Sea its abundance increases after cold winters (Beukema, 1979; Beukema & Essink, 1986).

Macoma balthica worms

Medium-sized Macoma balthica is the best con~promise available in the 6-species mix. INTRODUCTION Worms, crabs and shrimps are the most important prey for the majority of the 14 wader species occurring on the intertidal areas in NW Europe (Cramp & Sim- mons 1983). and may resemble small white worms. Like other macomas, M. balthica has scars on the insides of the valves, the two siphons are separate to the base, and the incurrent siphon lacks tentacles near the tip.

Competitive superiority of M. balthica over M. neglecta is likely due to the more efficient feeding regime of the bivalve (Kotta et al., 2004; Kotta, 2005). WoRMS taxon details.
