Effects of high suspended-sediment (SS) levels (up to c. 20,000 NTU) from fine clay on 5 species of New Zealand stream insects and the crayfish Paranephrops planifrons were assessed by short-term (24 h) exposures to different SS concentrations. There were no patterns of increasing mortality over 24 h with increasing SS concentrations. Effects of longer-term exposure (14 days) of repeated 4 h exposures to lower SS concentrations (c. 1000 NTU) on the common leptophlebiid mayfly Deleatidium were… CONTINUE READING
