Mya arenaria life cycle

Life History. Spawning/Larval Development. - Softshell clams typically have two spawns during a calendar year in the Chesapeake Bay, one in the spring and another during the fall. Both are triggered by temperatures in the 10-20oC range with optimal spawning temperatures 12-15oC. (Mya arenaria) along a latitudinal gradient. - ICES mar. Sei. Symp., 199: 19-25.

Mya arenaria. Mya arenaria ; la cuticule externe disparait rapidement après la mort du coquillage, laissant nettement apparaître les stries de croissance. Ce mollusque sinupallié est protégé par une coquille équivalve aplatie, allongée, à l'ornementation assez faible.

Temperature-dependence of mitochondrial function and production of reactive oxygen species in the intertidal mud clam Mya arenaria. Dynamics of Mya arenaria beds in two bights of the Chupa Inlet (Kandalaksha Bay, White Sea) were studied on a long-term basis. 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.

Maximum depth recorded is 329 m (Ref. 101279).Lives in burrows in sand, mud, sandy mud and sandy gravels from the mid shore to the shallow sublittoral, sometimes to a depth of 192 m (Ref. 78574).Commonly found in estuarine areas, buried in substrate 10 to 20 cm deep (Ref. 95344).In the Vainameri (north-eastern Baltic Sea), abundant in silty substrate (Ref. 95753).

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. The siphons are dark.

Previous studies on the gonadal cycles of Mya arenaria have divided the developmental se quence into five morphologically distinct phases: inactive, active ripe, spawning, and spent (Ropes and Stickney 1965; Porter 1974). Since semantic problems arise withthis usage, several terms are redefined for use here. The term "indifferent" is

The siphons are dark. M. arenaria lives Samples of three year-classes of the soft-shelled clam,Mya arenaria, were dredged at approximately two-week intervals from the mouth of the Patuxent River, Maryland. Changes in gonadal development were noted from histologically prepared sections of male and famale clams. Two separate periods of gametogenesis were noted. More gametes are formed during the autumn or primary period of maturation Soft-shell clams Mya arenaria also known as steamers. Wild, with some hatchery supplementation (seeding of flats with juveniles). Soft-shell clams burrow 8-14 inches into mud, sand, and gravel intertidal areas from Labrador to North Carolina.

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).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae Members of the class Bivalvia are mostly gonochoric, some are protandric hermaphrodites. Life cycle: Embryos develop into free-swimming trocophore larvae, succeeded by the bivalve veliger, resembling a miniature clam. Mya arenaria has a high fecundity and reproductive potential but larval supply is sporadic and juvenile mortality is high, so that although, large numbers of spat may settle annually, successful recruitment and hence recovery may take longer than a year.
