Mean progeny numbers and relative reproductive success (RRS) for hatchery and natural fish.

The hatchery fish are further categorized by their broodstock origin the prior generation (HHH = hatchery x hatchery, HHN = hatchery x natural, HNN = natural x natural). In each case, RRS is calculated as the hatchery mean divided by the natural mean for fish spawning in the same year.

孵化场繁育鱼类（hatchery fish）可依据其前代亲鱼来源进行细分：HHH对应孵化场亲本×孵化场亲本，HHN对应孵化场亲本×自然野生亲本，HNN对应自然野生亲本×自然野生亲本。在每一类群中，相对繁殖成功率（RRS，Relative Reproductive Success）均以同年度产卵鱼类的孵化场组均值与野生组均值的比值计算得到。
