Delaying spawning of lamellibranchs by low temperature

Spawning of oysters (Crassostrea virginica) and clams (Venus mercenaria) was delayed by transferring ripe or nearly ripe animals from Long Island Sound to the cold waters of Boothbay Harbor, Maine, where the temperature, although high enough to permit gametogenesis, was too low to induce spawning. With C. virginica, spawning could be postponed until six or eight weeks after the Long Island Sound population was completely spent, while V. mercenaria held over healthy summer spawn throughout the fall and winter and into the following spring. By similar means, laboratory workers can be provided with ripe animals during the fall when none are normally available in their own locality

Growth and setting of larvae of Venus mercenarid in relation to temperautre

Larvae of the hard shell clam, Venus mercenaria, were grown to metamorphosis at constant temperatures of 30.0, 27.0, 24.0, 21.0 and 18.0° C ± 1.0° C. The rate of growth of the larvae was generally, but not always, more rapid at high than at low temperatures. Within this range small differences in temperature, such as 1.0 or 2.0°, were not extremely important in affecting the rate of growth...
