Impacts - Benthic fauna Lewis et al., 2003. Harmful <strong>Alga</strong>e Ampelisca abdita (Amphipod) Mysidopsis bahia (Mysid shrimp) test organisms clay coagulant HAB organism Ampelisca abdita (infaunal amphipod) Leptocheirus plumulosus (infaunal amphipod) Palaemonetes pugio (grass shrimp) phosphatic clay (0.25 g/L) polyaluminum chloride (0.50, 5, 50 ppm) Karenia brevis (3.9 to 5.4 x 10 6 cells/L) main conclusions PWD RP T3200-1203 (1) The use of phosphatic clay and coagulant are not likely to have a detectable toxic effect on the benthos. Field validation needed. (2) Survival of the test species to clay, PAC and K. brevis was species-specific. specific. Survival, with one exception, was similar to K. brevis alone.
Impacts - Benthic fauna Archambault et al., in press. Marine Biology test organism clay organism Mercenaria mercenaria phosphatic clay (0.25 g/L) Heterocapsa triquetra M. mercenaria, notata strain RESULTS: Sedimented clay/cell floc (non-toxic) -No mortality occurred in any of the trials -Oxygen levels remained >85% saturation. -Significant growth in shell length and soft tissue occurred in all trials -Clams quickly recovered siphon contact with the overlying water column RESULTS: Suspended clay/cell floc (14 days) -A highly significant growth effect (~90% reduction in shell and tissue growth) with suspended clay compared to no-clay controls. -Repeated clay applications in the field are likely more detrimental to clams under flow conditions leading to prolonged in situ resuspension of clay than under conditions that promote rapid sedimentation.
