“…In reality bivalve larvae do not encounter such high salinity discontinuities. The rationale for selection of these values was to include extremes of the range of tolerance of each species (Chanley 1965, Calabrese 1969, Cain 1973, Castagna & Chanley 1973, Kennedy et al 1974, Roosenburg et al 1984) that could probably be encountered by larvae during their dispersal. The design assumes that if larval distribution was not affected by these extreme discontinuity values, then lower magnitudes or gradients as encountered in the field would make little or no difference to larval swimming behaviour.…”

Straight-hinge, umbo and pediveliger larvae of the mactrid bivalves Spisula solidissima, Mulinia lateralis and Rangia cuneata were exposed to intense salinity discontinuities of 0, 5, 10 and 15 O/w in vertically oriented swimming chambers. Larvae concentrated in the region of highest gradient, i. e. at the salinity discontinuity, regardless of species, stage of development or larval brood. S. solidisima larvae, initially swimming at 30 O/w salinity, crossed discontinuities of both 5 and 10 %O but not of 15 %o. M. lateralis larvae, initially swimming at 25 %O salinity, also crossed a discontinuity of 5 %O but not of 10 or 15 %o. R. cuneata larvae, initially swimming at 10 %O salinity, generally preferred to remain at that salinity. Swimming and passive sinking velocities, defined as vertical distance traversed per unit time, were measured in different salinities under constant temperature and light. For all species, swimming rate changed with larval stage, highest velocity occurring at the umbo stage. Upward swimming rate of S. solidissima larvae ranged from 0.18 to 0.49 mm S-' and increased with increasing salinity. Upward swimming rate of M. lateralislarvae ranged from 0.25 to 0.50 mm S-', but was not consistently related to salinity. Upward swimming rate of R. cuneata larvae ranged from 0.18 to 0.53 mm S-'; swimming rate of pediveliger larvae increased consistently as salinity decreased. Downward swimming rates were similar to upward rates. No significant differences in downward swimming rate were detected in relation to salinity. Passive sinking was more frequent than active downward swimming in umbo and pediveliger larvae. Sinking rate increased with larval size of S. solidissima and M. lateralis larvae; however, R. cuneata straight-hinge larvae sank faster than umbo and pediveliger larvae. Species-specific differences in larval sinking and swimming are related to the different habitats occupied by adults. Larvae of S. solidissima, a marine stenohaline species, remained in high salinity water. Larvae of M. lateralis, a euryhaline species, use their preference for discontinuities or higher salinity water to assist retention in partially mixed estuaries. High sinking rate and short larval period of R, cuneata may offset the behavioural characteristic and aid in the retention of R. cuneata larvae in the low salinity zone of most partially mixed estuaries.

Larval Behavior and Protective Implications for Sea Scallops and Surf Clams within the Middle Atlantic Bight: Part One, a Sensitivity Study

In this study, sensitivity studies of larval behaviors were performed, using numerical modeling and analytical methods, for sea scallops (Placopecten magellanicus) and surf clams (Spisula solidissima) in the Middle Atlantic Bight during 2006 and 2010. Based on multiple experiments, a regional ocean modeling system (ROMS) was implemented as the primary physical model, and larval individual behavior models (IBMs) for sea scallops and surf clam larvae were implemented and coupled to the ROMS. To simulate the physical environment and larval behavior using a series of numerical experiments, he coupled ROMS and IBMs were then employed and were driven by realistic dynamic forcing (e.g., winds, tides, and climatological mean boundaries), thermo-dynamic fluxes (e.g., solar radiation, sensible and latent heating), and hydrological forcing for larval behaviors such as vertical swimming and sinking, horizontal drifting with currents, growth, and settlement. Various growth patterns, release types, and larval behavioral parameters were analyzed and are summarized here, based on implications for the protection of sea scallops and surf clam larvae in the Middle Atlantic Bight.
