The facultative deposit-feeding clam Macoma balthica is used as a bioindicator organism for assessing coastal metal contamination. Previous work has evaluated the assimilation of metals from different possible food sources for this clam, but no studies have measured the uptake rates of metals from different dissolved sources. 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.

Macoma balthica (Linnaeus, 1758) Limecola balthica , commonly called the Baltic macoma , Baltic clam or Baltic tellin , [1] [2] is a small saltwater clam , a marine bivalve mollusk in the family Tellinidae (the macomas and tellins). The facultative deposit-feeding clam Macoma balthica is used as a bioindicator organism for assessing coastal metal contamination. Previous work has evaluated the assimilation of metals from different possible food sources for this clam, but no studies have measured the uptake rates of metals from different dissolved sources.

Lin & Hines (1994) mentioned a maximal radius of 10 cm, but their data referred to the larger American M. balthica up to 39 mm long. 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. 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. The density of harpacticoid copepods was lowest (P <0.05) in microcosms containing a high density of M. balthica.

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. Macoma balthica is widely distributed throughout north-west Europe and Britain. It has a plump almost circular shell, up to 25 mm in length, with umbones close to the midline. The posterior of the shell may be very slightly tapered.

AU - Bunskoeke, Arjo (E.J.) AU - Ens, Bruno J. AU - Hulscher, Jan B. AU - DeVlas, SJ. PY - 1996. 1980-01-01 The facultative deposit-feeding clam Macoma balthica is used as a bioindicator organism for assessing coastal metal contamination. Previous work has evaluated the assimilation of metals from different possible food sources for this clam, but no studies have measured the uptake rates of metals from different dissolved sources. The feeding radius of M. balthica and S. plana is a linear function of shell size. 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.
