Macoma balthica was implicated in the Mersey bird kill in the late 1970's, owing to bioconcentration of alklyC-lead residues (Bull et al. , 1983). 1980-01-01 · M. balthica feeds on surface deposits at low tide by sorting surface sediments in its mantle cavity. It ingests 12% (by weight) of the sediment and releases the remainder as a loose plume of pseudofeces.

(1981) reported adult densities in the Humber Estuary, UK, between 5,000/m² and 40,000/m² depending on time since a successful spatfall. Bonsdorff et al. (1995) reported juvenile density 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 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.

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.

Östersjömussla (Limecola balthica eller Macoma balthica) är en liten mussla som förekommer i norra Atlanten, inklusive i Nordsjön och i Östersjön. Den finns också i norra Stilla havet. Musslan blir cirka 2,5 centimeter stor och lever nergrävd i sandiga eller leriga bottnar. Dess tomma skal kan hittas uppspolade på stranden.

Limited information is currently available on metal ENP effects, uptake, and depuration kinetics in aquatic organisms. In the present study, a deposit-feeding clam, Macoma balthica, was exposed to sediment spiked with Ag and Cu in different forms (aqueous ions, nanoparticles, and micrometer-sized particles) in three experiments.

The tellinid Macoma balthica moves extensively about the surface of the sand, its activities not being restricted to vertical movements as hitherto supposed. These horizontal migrations comprise a movement towards the sun followed by a movement away from it. If there is heavy cloud movements still occur, in summer at least, but are at random.

We found that, depending on species-specific traits, deposit-feeding macrofauna an amphipod, monoporeia affinis , a bivalve, macoma balthica and an invasive  both suspension- and deposit-feeding modes (Brafield & Newell 1961; Bubnova 1972). According to Bubnova, M. balthica filter feeds when suspended food material is abundant and begins deposit feeding as the food supply decreases. Based on these observations, M. balthica was assumed to function as a suspension feeder on an exposed, sublittoral, sand Feeding Macoma balthica in NIOZ aquarium Brafield & Newell (1961), Gilben (1977) and Kamermans & Huitema (1994) recorded for M. balthica a maximal feeding radius of 4, 6 and 5 cm, respectively, close to present values.

Journal of Marine Research, 42, 957-968, 1984 The role of bacterial exopolymer and suspended bacteria in the nutrition of the deposit-feeding clam, Macoma balthica by Ronald W. Harveyl and Samuel N. Luomal ABSTRACT Potential nutritional contributions of bacterial exopolymer and suspended bacteria to the detritus feeding estuarine clam, Macoma balthica, were examined separately in laboratory

Highest frequencies of yellow shells are found in northeastern Atlantic Macoma (Beukema & Meehan, 1985), ironically called M. balthica ‘rubra’ (ruber is Latin for red). Limited information is currently available on metal ENP effects, uptake, and depuration kinetics in aquatic organisms. In the present study, a deposit-feeding clam, Macoma balthica, was exposed to sediment spiked with Ag and Cu in different forms (aqueous ions, nanoparticles, and micrometer-sized particles) in three experiments. abundance was reduced by both Mya arenaria and Macoma balthica, with the greatest decline feeding bivalves may be maintained through interactions.

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.
