Figure 9

The loge-transformed (ln) frequency of catch at age (years) for adult alewife n = 363, ln (n/sum n = −1.20 (age) + 4.48, r2 = 0.81, ----) sampled during 2016–2019 in the La Coupe (n = 46, ■), LaPlanche (n = 137, ●), Missaquash (n = 134, ▲), and Tantramar (n = 46, ♦) rivers of the Chignecto Isthmus, Bay of Fundy, Canada. Total instantaneous mortality of Z = 1.20 for fish aged four–six years.
