Shell length of juveniles rarely exceeded 2 mm in 1995, which was most A threshold of 50% entrainment of juvenile M. arenaria occurred at a flow speed between 30 and 34 cm s − 1 while 50% entrainment for M. mercenaria occurred between 37 and 40 cm s − 1; entrainment of G. gemma was < 50% at the single flow speed to which it was exposed, 37 cm s − 1 (). Patchy distribution is frequently observed in benthic marine invertebrates. In order to indentify factors causing spatial patterns in the bivalve Mya arenaria, abundances of juveniles and adults, as well as death assemblages, were recorded on a 20-km scale in the intertidal zone of the Sylt-Rømø Bight. Both adults and juveniles exhibited pronounced patchiness. Shell length of juveniles B) and cultured (C and D) juvenile softshell clam, Mya arenaria (length ca. 15 mm).

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. 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.

Juvenile specimens of Mya arenaria were more abundant in the mid-intertidal zone. However, juvenile specimens of Scrobicularia plana were mainly distributed in the upper intertidal level, which suggests that they have a different settlement behaviour from that observed for the juveniles of the invasive clam. 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. juvenile Mya arenaria burrowed into sediment of different Ω aragonite after 20 mins was tested for effects of Ω aragonite and clam size class (0.5-1.5 mm and 1.51-2.5 mm)..

The wild clam was sampled from a mudflat in Roque Bluffs, Maine, in September 1992. The cultured clam was reared at the Beals Island Regional Shellfish Hatchery and planted in May 1990, in a mudflat at the mouth of the Chandler River, near the town of Jonesboro 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).
