Abstract

Eggs of herring artificially fertilized in the laboratory, were exposed either to different constant concentrations of suspended silt (about 5-300 mg 1** minus **1) or to short-term high concentration (500 mg 1** minus **1) at different times during embryonic development. These experiments were made to test the effect of the increased turbidity near marine mining, spoil disposal or dredging operations. Embryonic development was unaffected by suspended silt. Mortality rates varied significantly between aquaria, but the variation was unrelated to the experimental treatment with silt. Refs.
