Manila clams (Ruditapes philippinarum) of A. Small and B. Large size classes remaining in experimental units after a six-week experimental manipulation of predator access, across the green crab catch rate (catch per unit = mean number per trap) at eight sites in Willapa Bay, Washington. Each unit was seeded with 20 small and 5 large clams on 11–12 July 2024. Each point represents the mean remaining on 23–24 August 2024, with the standard error (N = 5). From left to right, the sites are: WOL, PO, WO, BR, DP, STS, OY, STC.
