Abstract
    This research was initiated to study the effects of silvex (PGBEE) on animals and plants in farm ponds and to determine the silvex residues in animals. Three farm ponds were selected for the study and sampled on a regular monthly basis. Fish were sampled by seining, shocking, netting and by direct observation. Quantitative benthic samples were taken monthly before treatment and at shorter intervals after treatment. Bluegill and carnivorous fish were collected at regular intervals for gas chromatograph analysis of the Silvex residues. The ponds were treated with silvex at the rate of eight pounds acid equivalent per surface acre.
