Figures & data
Figure 1. Age-bias plots of dorsal fin spines and pectoral fin rays used to age common carp (N = 309) sampled from three North Dakota lakes. Precision between structures was evaluated as exact PA, PA within 1 year (value within parentheses), and mean CV. Numbers in circles represent the number of common carp of each estimated age.
Figure 2. Age-bias plots for dorsal fin spines and pectoral fin rays used to age common carp (N = 309) sampled from three North Dakota lakes. Precision between readers was evaluated as exact PA, PA within 1 year (value within parentheses), and mean CV. Numbers in circles represent the number of common carp of each estimated age.
Figure 3. Age-bias plots for dorsal fin spines and pectoral fin rays used to age common carp (N = 309) sampled from three North Dakota lakes based on a joint viewing. Precision between readers was evaluated as exact PA, PA within 1 year (value within parentheses), and mean CV. Numbers in circles represent the number of common carp of each estimated age.
