Abstract

Black crappie (Pomoxis nigromaculatus) and white crappie (Pomoxis annularis) are two popular sportfish species distributed widely throughout much of the United States. Maintaining crappie populations is a concern because their numbers tend to fluctuate considerably in terms of recruitment (number of young fish surviving to adulthood), abundance, and growth. Such fluctuations often result from several environmental and biological variables working concurrently. However, one important variable affecting crappies is turbidity, a measure of water clarity. Turbidity alters the behavior of many aquatic species, including crappies, often resulting in reduced growth, changes in abundance, and shifts in feeding preference.
