How Suspended Organic Sediment Affects Turbidity and Fish Feeding Behavior
Madej M. 2004. How Suspended Organic Sediment Affects Turbidity and Fish Feeding Behavior. Sound Waves: Coastal Science and Research News from Across the USGS. FY 2005(67):7-8
Excerpt from article: "Salmon need clear water to see their prey, such as aquatic insects and other macroinvertebrates; yet many of these same prey feed on suspended organic particles that cloud the water. Salmon health, then, depends on a balance between water clarity and the turbidity caused by suspended organic particles that sustain their prey. A team of researchers from the U.S. Geological Survey (USGS) and Humboldt State University are taking a close look at this balance, partly in response to concerns about coastal streams whose water clarity is becoming increasingly impaired by such land uses as grazing, mining, timber harvest, and road construction."
