Abstract
To determine the potentiality for dispersal of Asiatic clams (C. manilensis) via the intestinal tract of waterfowl, live clam specimens were force-fed to adult male lesser scaup ducks (Aythya affinis). Examination of duck excreta revealed no egestion of viable individuals. In a 2nd experiment, a simulated waterfowl gizzard was utilized to determine the chemical and physical effects of avian digestion on live Asiatic clams. Mortality of test clams was 100% after 1 min exposure in a solution of synthetic gastric juice.This publication has 6 references indexed in Scilit:
