Macoma balthica feeding

The burrowing behavior of the deposit feeding bivalve Macoma balthica reflects a typical food-safety trade-off. The choice to live close to the sediment surface comes at a risk of predation and is a decision made when predation danger, food intake rates or future fitness prospects are low. Two months later the tellinid bivalve Macoma balthica was added in quantities varying from 0 to 40 individuals per microcosm. After 5 months the effects of the bivalves on the meiofauna were surprisingly small.

feeding species, Macoma balthica. Simulated increases in chlorophyll a and TSS resulted in corresponding increases and decreases in hard clam weight, respectively. Model structure did not allow for changes in these parameters to be examined specifically for Macoma balthica but interannual changes in individual weight showed less variation

Macoma balthica - potential feeding area (PFA) Single specimens were measured to the lower 0.1 ram, placed in a tray filled with 6 cm natural sediment and kept at 12~C. The,animals buried themselves very rapidly and started to suck material from the surface with their inhalent siphon. The area which had For Macoma balthica, fecal pellets were collected every 1 h for the first 36 h of cold feeding Sub- sequently, pellets were collected every 12 h for up to 7 d. The number of pellets produced at each interval was noted.
