Macoma balthica feeding

Keywords: Food  Macoma balthica (Linnaeus, 1758).

The density of harpacticoid copepods was lowest (P <0.05) in microcosms containing a high density of M. balthica. It is suggested that competition for food resources was responsible for this pattern. Feeding activities of the clams were observed for about ten minutes at irregular intervals for 22 times during the experiment. The number of M. balthica exhibiting de-posit or suspension feeding behavior was recorded.
