It either holds its feeding organ, the siphon, at a fixed position just above the sediment surface to filter out food particles suspended in the overlying water or else extends and moves its siphon As a characteristic buried tellinid bivalve, Macoma balthica has a long inhalent siphon that enables it to feed in two different ways: deposit and suspension feeding. 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. In the course of the summer an increasing mortality occurred amongst Deposit and suspension feeders can switch feeding behavior and show variations in feeding mode as individuals pass through life-cycle stages.

Macoma balthica is tha most significant producer of copious amounts of resistant fecal pellets in the muddy intertidal ·areas.

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.

The ingested sediment is returned to the tidal flat surface within 3 - 6 h as compact fecal pellets. These pellets behave like fine sand grains. experimental aggregates of the deposit-feeding bivalve Macoma balthica* Karsten Reise Biologische Anstalt Helgoland, Litoralstation, D-2282 List. Federal Republic of Germany In this paper an analysis is made of subtle behavioural differences between adult male and female Ovstercatchers feeding on Macoma balthica under field conditions and in captivity.

We made week-long experiments on the rate of feeding on 14 C-labelled diatoms spread on the sediment surface in different oxygen concentrations for both the amphipod species, M. balthica and H. spinulosus. The amphipods were the most sensitive to oxygen deficiency and showed reduced feeding and lower survival at low oxygen concentrations.

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. Mature Macoma balthica are rarely over 25 mm long (Dunnill and Ellis 1969), but could be confused with the young of some of these larger clams. Other genera of Tellinidae (ie. Tellina sp.) have lateral hinge teeth (at least in the right valve); Macoma do not. Macoma are generally more rounded and more inflated than Tellina; Macoma are smooth The feeding radius of M. balthica and S. plana is a linear function of shell size.

Large specimens are infected to a larger percentage than small ones. In the course of the summer an increasing mortality occurred amongst Deposit and suspension feeders can switch feeding behavior and show variations in feeding mode as individuals pass through life-cycle stages.

Deposit and suspension feeders can switch feeding behavior and show variations in feeding mode as individuals pass through life-cycle stages. Stable carbon and nitrogen isotopes were used to trace changes in diet of the tellinid bivalves M. balthica (facultative deposit feeder) and C. edule (obligatory suspension feeder), according to their size class.

Feeding behavior of Macoma balthica is influenced in the Neuse River estuary by both hydrodynamics and siphon-cropping by juvenile demersal fishes. Under conditions of identical concentrations of suspended particulates in the water column and organic contents of surface sediments, Macoma exhibited much higher levels of deposit feeding where currents were slower.
