Abstract

Erosion and dumping lead to increased concentrations of mineral particles in coastal waters. The muddy waters contained high concentrations of hydrophylic limestone particles 2–50 microns in diameter. Accumulations of these particles on the sea floor can lead to the mortality of benthic macro-organisms. Using laboratory experiments, we studied the impact of dumping from mines on the mobility, feeding and reproduction of the pelagic suspension-feeder Acartia. Increased particle load changes copepod locomotive and digestive processes. Nauplii production per female decreased about 7 times in waters polluted with mineral particles. A conceptual model of mineral particle concentration impact on suspension-feeders is presented.
