Comparison between model simulation results and observations for adult population biomass and catch. Model simulated a age-1 and older anchovy biomass and catch from FAO from 1958 to 1990 and b age-1 and older sardine biomass and catch from FAO from 1964 to 1990. Model simulation data is plotted in black line with close circles and FAO data is plotted in gray line with crossed through
