Abstract

Simultaneous and sequential tests of pump sampling equipment showed that sampling mortality of Lake Michigan zooplankton collected from the cooling water intake of a nuclear power plant was dependent on the sampling method used. Two sampling devices and two pump types were tested to determine which combination resulted in the lowest sampling mortality. An in-line filter trap located on the suction side of the pump provided the lowest sampling mortality. Higher sampling rates were achieved with a centrifugal pump without increasing sampling mortality.
