Summary, Etc. Note: |
Abstract: The Asiatic clam and a clam native to the southern United States (Magnonaias), were exposed to the fish toxicant antimycin at several concentrations for various periods and then placed in an untreated earthen pond for posttreatment observation. Both species survived the concentrations and exposure periods usually used in field application. However, latent mortalities were observed in the pond 3 months after a 30-day flow-through exposure of the Asiatic clam to 3.6 to 30 microgram/liter of antimycin. A single treatment (2 microgram/liter) in an earthen pond did not result in significant mortalities of Asiatic clam during 22 weeks. The clam native to the United States (Magnonaias) was more sensitive than the Asiatic clam to antimycin, but both survived the maximum permissible use-pattern concentrations in flow-through tests. |
