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).

In the course of the summer an increasing mortality occurred amongst ELSEVIER Journal of Sea Research 41 (1999) 203–212 Reproductive investment in the intertidal bivalve Macoma balthica P.J.C. Honkoop ,J.VanderMeer,J.J.Beukema,D.Kwast Netherlands Institute for Sea Research (NIOZ), PO Box 59, 1790 AB Den Burg, Texel, The Netherlands 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 OSTI.GOV Conference: Availability of sediment-bound cobalt, silver, and zinc to a deposit-feeding clam.

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. Macoma is a tellinid bivalve that in the Dutch Wadden Sea is mainly preyed upon during spring and summer when it is buried at a shallow depth. males lift Macoma more, whereas females handle them mostly in situ. Results from this study were compared to 28-day bioaccumulation experiments involving PCB-contaminated sediment from Hunters Point Naval Shipyard (San Francisco Bay, CA) and the clam Macoma balthica. Due to differences in feeding strategy, M. balthica deposit-feeds whereas C. fluminea filter-feeds, the relative importance of the aqueous uptake route is predicted to be much higher for C Contrasting influences of suspension-feeding and deposit-feeding populations of Macoma balthica on infaunal recruitment @article{lafsson1989ContrastingIO, title={Contrasting influences of suspension-feeding and deposit-feeding populations of Macoma balthica on infaunal recruitment}, author={E. {\'O}lafsson}, journal={Marine Ecology Progress Series}, year={1989}, volume={55}, pages={171-179} } Barite, an important component of offshore drilling muds, is shown to adversely affect the ctenidia of the suspension feeding bivalve, Cerastoderma edule and the deposit feeder, Macoma balthica.

Macoma balthica is tha most significant producer of copious amounts of resistant fecal pellets in the muddy intertidal ·areas. Macoma balthica is not normally considered to be toxic but may transfer toxicants through the food chain to predators.

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. 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. Macoma balthica ‘balthica’, in the Baltic Sea and White Sea, has relatively many red shells (Väinölä & Varvio, 1989; Strelkov et al., 2001; Sokolowski et al., 2002). 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.

[citation needed] Feeding activities of the clams were observed for about ten minutes at irregular intervals for 22 times during the experiment.

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.
