Observations of Spatial Heterogeneity in the Age Distribution of Black Crappie in B. E. Jordan Reservoir

In October 1997, apparent spatial heterogeneity in the black crappie (Pomoxis nigromaculatus) age distribution was observed in B.E. Jordan Reservoir. The number of age groups for black crappie increased from downlake to uplake. The objective of this study was to verify this spatial heterogeneity. Trap nets were used to collect black crappie in 4 sections of the reservoir. Black crappie ages ranged from 1 to 17 years, and fish ≥10 years were found only in the upper 2 sections of the reservoir. Significant (P<0.05) differences in the black crappie age distribution were found between most...
