74TABLE B-1. Estimates of the MSY of yellowfin tuna, and associated quantities, for the base case assessment (no stock recruitmentrelationship, steepness [h] = 1), and a sensitivity analysis including a stock-recruitment relationship with h = 0.75. All analyses arebased on average fishing mortality for 2006-2008. B recent and B MSY are the biomass of yellowfin tuna 2+ quarters old at the start of2009 and at MSY, respectively, and S 2009 , S MSY , and S F=0 are indices of spawning biomass (relative number of eggs) at the start of2009, at MSY, and without fishing, respectively. C 2008 is the estimated total catch in 2008.TABLA B-1. Estimaciones del RMS del atún aleta amarilla, y cantidades asociadas, para la evaluación del caso base (sin relaciónpoblación-reclutamiento, inclinación [h] = 1), y un análisis de sensibilidad que incluye una relación población-reclutamiento, con h= 0.75. Todos los análisis se basan en la mortalidad por pesca media de 2006-2008. B reciente y B RMS son la biomasa de atún aletaamarilla de 2+ trimestres de edad al principio de 2009 y en RMS, respectivamente, y S 2009 , S RMS , y S F=0 son índices de la biomasareproductora (número relativo de huevos) al principio de 2009, en RMS, y sin pesca, respectivamente.
