The database: from Age, Growth and Food habits of the Flier sunfish (Centrarchus macropterus Lacepede) in northeastern North Carolina with an evaluation of the effect of environmental variables on growth. 1978. M S Thesis. North Carolina State University, Raleigh, N. C. 88 pp.
Flier sunfish from various sites in 3 stream basins in northeastern North Carolina. Six hundred and thirty eight specimens were captured between September 1974 and April 1976. Aged with a key scale depicted below. Fish lengths are in cm, weights in gms and scale measurement in cm on projected (magnified) scales.
