88 FIGURE D-8. MSY (upper panel) and the change (increase or reduction) in the effort required to produce the MSY (lower panel) for bigeye tuna, estimated separately for each year, using the average age-specific fishing mortality for that year. FIGURA D-8. RMS (recuadro superior) y cambio (aumento o reducción) <strong>del</strong> esfuerzo necesario para producir el RMS (recuadro inferior), de atún patudo, estimado por separado para cada año, usando la mortalidad por pesca promedio por edad de ese año.
FIGURE D-9. Phase plot of the time series of estimates of stock size (top: spawning biomass, S; bottom: total biomass, B) and fishing mortality (F) of bigeye relative to their MSY reference points. Each dot is based on the average exploitation rate over three years; the large dot indicates the most recent estimate. FIGURA D-9. Gráfica de fase de la serie de tiempo de las estimaciones <strong>del</strong> tamaño de la población (arriba: biomasa reproductora, S; abajo: biomasa total, B) y la mortalidad por pesca (F) de atún patudo en relación con sus puntos de referencia de RMS. Cada punto se basa en la tasa de explotación media de tres años. El punto grande indica la estimación más reciente. 89
