Effects of Underwater Sound Simulating the Intermediate Scale Measurement System on Fish and Zooplankton of Lake Pend Oreille, Idaho

Abstract

We conducted in-situ experiments to study effects of simulated ISMS sound on zooplankton abundance and biomass, kokanee feeding and growth, predator/pre interactions, kokanee behavior, and kokanee embryo survival. Frequencies of 100,800 and 5,600 Hz at sound pressure levels ranging from 105-167 dB re 1 microPa were used to ensonify aquatic organisms. Response variables from ensonification experiments were compared to controls for evidence of ISMS effects. Neither zooplankton abundance and biomass nor growth of age-0 kokanee were affected as a result of stimulated ISMS ensonification. Similarly, we found no evidence that kokanee embryo survival was reduced as a result of simulated ISMS sound.
