tors causing spatial patterns in the bivalve Mya arenaria, abundances of juveniles and adults, as well as death as-semblages, were recorded on a 20-km scale in the inter-tidal zone of the Sylt-Rømø Bight. Both adults and juve-niles exhibited pronounced patchiness. Shell length of juveniles rarely exceeded 2 mm in 1995, which was most

Shell length of juveniles rarely exceeded 2 mm in 1995, which was most Mya arenaria is a large long-lived bivalve. The shell is dirty white or fawn in colour with a fawn or light yellow periostracum.

The studied soft-shell clam beds were characterised by a substantial instability of age structure. Since 1988, only one year-class has dominated in the beds while other generations have PDF | We present some of the few suspension-feeding measurements and to our knowledge the first velocity-field measurements for early post-settlement | Find, read and cite all the research you A series of field experiments was conducted at two intertidal sites in the Hampton Seabrook Estuary from November 2004-2006 to assess the efficacy of enhancing intertidal areas with cultured clam (Mya arenaria L.) seed (mean shell length [SL] = 7-10 mm). Measurement variables in each experiment included survival and growth of both cultured and wild seed clams. The first of three trials Mya arenaria. Experiments were conducted in May (first Crangon septemspinosaexperiment), July (Car-cinus maenasexperiment) and November (second C. septemspinosa experiment) 2001. The source and size of juvenile Mya arenaria varied among experiments because of constraints in availability of clams from hatcheries and of the flume facilities.

Increasing juvenile soft-shell clam (Mya arenaria) recruitment has been the focus of several shellfish committees along the New England coast in an effort to increase harvestable biomass. This study recreated three previously used enhancement techniques to determine if the treatments had any effect on juvenile soft-shell clam recruitment.

The purpose was to measure the effects of hydrodynamic conditions, substrate, and clam size on dispersal in controlled laboratory condition and to interpret these results in Video S1 from Overcoming hydrodynamic challenges in suspension feeding by juvenile Mya arenaria clams. A video showing the inhalant and exhalant flows produced by a juvenile Mya arenaria clam. The image plane transects both inhalant (top) and exhalant siphon velocity fields, and the animal's ventral side faces the top of the frame. Rates of mortality and transport of newly settled benthic invertebrates can be very high and potentially have profound effects on patterns of recruitment. We used the soft shell clam Mya arenaria a M. arenaria .
