Pulse-Power: A Possible Alternative to Chemicals for Zebra Mussel Control; Summary of 2000 Field Studies

摘要

Field studies were conducted in 2000 to determine if the effects of pulse-power electric field systems could be evaluated by examining zebra mussel planktonic life stages. Evaluating plankton was a major variation from previous study methods and objectives. In the past, the older settlement stage was the target stage and a high control rate was the goal. In the 2000 studies, it was necessary only to have a consistent effect on plankton in the 20- to 60-percent range for them to be of value as a tool; high control of plankton was not expected or required. The first objective of the 2000 study was to evaluate effects of an electric field with a given set of electrical parameters on the behavior of planktonic zebra mussels. The second objective was to determine if the modified Megapulse electrical system would remain functional in a long-term settlement study.
