Turbidity and Appearance of Water

Abstract

Turbidity and the appearance of water are important considerations in pond aquaculture. If pond waters are clear and light can penetrate to the pond bottom, underwater weeds consisting of both macrophytic algae and vascular plants will develop. These plants compete with phytoplankton for nutrients, and they impede various pond management procedures. Clear water also makes aquatic animals more susceptible to bird predation. Production will be less in clear ponds than in ponds within the proper turbidity range. The appearance of water, such as color and presence of foam or scums, also can provide clues to water quality characteristics.
