Book Description
In April 1987, soft-shell clams in a small intertidal area of the Annapolis Basin, N.S. were found dead. Since live and apparently healthy clams were still found in the higher beach region at this location, it was decided to set up experimental plots in the area of dead clams to determine if mortality factors were still acting. A 100% mortality of transplanted experimental clams within 2 months indicated that this was the case. Although there is evidence from preliminary laboratory studies that predation by the ribbon worm may have occurred, this is believed not to be the cause of the mortality. As part of an investigation to determine the cause of this mortality, sediment and clams were collected in October, 1987 from the dead clam area and a nearby tidal flat as a control. In the laboratory, sediments, half of which were autoclaved to remove microorganisms, were placed into running seawater tanks into which healthy clams were transplanted. The clams were observed for 3 months and the sediment was tested for pesticides, heavy metals, and PCBs.
