Soft-shell clams are among the state's five most valuable fisheries, but recent population declines in eastern Maine have led to speculation that agricultural pesticides and herbicides might be a contributing factor. In laboratory toxicology experiments, the researchers will expose clams to several pesticides commonly used on fields and found in eastern Maine rivers. These data will be used to build a matrix population model to determine potential population-level effects of toxicity on soft-shell clams.
