| Abstract | Estuarine grass shrimp (Palaemonetes pugio) and pink shrimp (Penaeus duorarum) were deployed in floating cages to determine if fenthion, in an actual-use application in the field, affected shrimp survival. After four ultra-low-volume ground applications (equivalent to llg/ha or 0.01 lb/acre) to control salt marsh mosquitoes, deaths of caged grass shrimp or pink shrimp were not attributed to fenthion exposure. Suspect causes of reduced survival of shrimp include both low salinity and dissolved oxygen, daily excursions in water temperature, and stresses due to handling, acclimation, and confinement. |
