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. Each Linear growth of soft-shell clams, Mya arenaria L., was studied at six locations in the White Sea situated in the middle and low tidal zones. The main aim was to analyse the growth heterogeneity both within beds (with respect to individual growth) and between beds (with respect to group growth). Mya population was characterized by a slow growth and a long lifespan. Maximum shell size was 70 In this dissertation, I explored metapopulation dynamics and population connectivity, with a focus on the softshell clam, Mya arenaria.

Sammanfattning: A laboratory flume was used to examine the retention of juvenile soft-shell clams (2 wk postsettlement) in sediment when exposed to flow. on the diet (inferred from stable isotopes of muscle tissue), size and percent nitrogen of the soft-shell clam (Mya arenaria), a sedentary estuarine consumer. av H Forslund · 2012 · Citerat av 2 — 2009).

For 1.8-2.8 mm shell length Mya arenaria clams, pumping rates ranged 0.03-0.22 μl s-1, inhalant siphon Reynolds numbers (Re) ranged 0.16-0.79 and mean inhalant velocities ranged 0.8-3.2 mm s-1 Owing to the low Re at which they pump and the small diameters of their siphons, juvenile clams are subject to unique hydrodynamic challenges, including high siphon resistance and susceptibility to refiltration.

Earlier studies demonstrated that densities of 0-y-old individuals of Mya arenaria L. were lower in Washington County on the eastern Maine coast than in Cumberland County on the southern Maine coast. Reduced juvenile recruitment could result from reduced larval abundances, high postsettlement mortality, or a combination of Soft-shell clam, Mya arenaria, culture on the east coast of Canada is characterized by high loss following seeding.
