T Université du Québec à Rimouski, Rimouski, Département d'Océanographie, Québec, G5L … This study identifies early, postmetamorphic soft-shell clams, Mya arenaria, as the life-history stage most susceptible to effects of blooms of paralytic shellfish poisoning (PSP) toxin–producing Alexandrium spp. Laboratory experiments used progeny from predominantly susceptible (naı¨ve) or resistant (annually exposed) NW Atlantic populations. Mya arenaria, is in the order Eulamellibranchia, Suborder Heterodonta, and Family Myidae. Its valves are oval in shape, generally average less than 13 cm in length, and are usually white or gray in color with a periostracum of yellow or brown.

Observations were carried out at 1– to 3-year intervals from 1979 up to 1999. The studied soft-shell clam beds were characterised by a substantial instability of age structure.

2014-01-01 · 1. Introduction. In the Baltic Sea and its estuaries, water salinity is one of the key factors determining the occurrence, distribution, and abundance of species via its effect on the functional ecology of aquatic animals (e.g. growth rate, life cycles, production, and energy flows) (Kullenberg, 1991, Gogina and Zettler, 2010, Ojaveer et al., 2010, Bleich et al., 2011). The softshell clam, Mya arenaria, is a commercially important bivalve species that.
