Figure 5 in Effects of dams on demographic structures of amphidromous fish and crustacean species in Caribbean rivers

Figure 5. – Individual number histograms of each species broken down by size classes (mm) for the three stations (top chart) and porosity chart of the Grand Carbet River water intake (bottom chart). Bottom chart: arrow indicates the optimal size at crossing; dotted black line indicates 50% crossing; dotted grey lines indicate the mean crossing rate for these size classes. The size of the downstream and upstream population of Macrobrachium faustinum is too small and fragmented to be presented.
