Number of SBT samples by fork length (<i>FL</i>), dressed weight (<i>DW</i>), sex, otoliths and age spawning season.

Estimates of percent female (%F), mean length, mean age, age diversity (Shannon-Weaver) index, and bigeye (BE) index are shown for samples from the spawning ground only. Samples caught south of the spawning ground have been excluded (see text for details). * Indicates significant χ2-tests (P<0.05) (i.e., % females significantly different than 50%).仅针对产卵场采集的样本，给出了雌性占比（percent female, %F）、平均体长、平均年龄、年龄多样性香农-韦弗指数（Shannon-Weaver）以及大眼金枪鱼指数（bigeye, BE）的估算结果。产卵场以南采集的样本已被排除，详细说明参见正文。* 代表卡方检验（χ²检验）结果显著（P<0.05），即雌性占比显著异于50%。
