Abstract In the Corophium-zone about 20% of Macoma balthica present makes feeding tracks indicating they were deposit feeding; no feeding tracks are found outside the Corophium-zone. The infection rate in summer of Macoma by a gymnophallid trematode was studied. Large specimens are infected to a larger percentage than small ones. In the course of the summer an increasing mortality occurred

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. Bu-rial depths of M. balthica were measured every three to four days until the clams' burial depth became stable.

(1981) reported that Limecola balthica from the Humber Estuary, UK, tolerated 6 hours of exposure to temperatures up to 37.5°C with no mortality. that 2 populations of Macoma balthica differ in their feeding modes between habitats. One population, in a sublittoral, sheltered, muddy-sand sediment, is primar- ily deposit-feeding while the other population, in a sublittoral, wave-exposed, sandy sediment, is primarily suspension-feeding.

S. plana use half of their siphon length to feed on the surface and the other half to bury themselves, but if the siphon weight is below average, the proportion extended over the surface decreases with siphon size.

Macoma balthica (L.) is a common clam of the estuarine seafloor, belonging to an important group of invertebrates possessing the capacity to choose between the two fundamental modes of feeding available, using its siphon to inhale either suspended food particles from the water or food particles deposited on the sediment surface.

To deposit feed efficiently on benthic microalgae, Macoma has to live close to the sediment surface, where it can graze an extensive surface area, but is within reach of many predators. Individuals that are more safely buried at In the Corophium-zone about 20% of Macoma balthica present makes feeding tracks indicating they were deposit feeding; no feeding tracks are found outside the Corophium-zone. The infection rate in summer of Macoma by a gymnophallid trematode was studied. Large specimens are infected to a larger percentage than small ones.
