在土地被荒弃的几十年内，原始生物量恢复一半。
Within a few decades of land being abandoned, half of the original biomass has returned.
这一点很重要，因为理论表明，当目标鱼种的生物量为其原始水平的50%左右时，渔场才能达到可收获的最大可持续产量。
That matters because theory suggests that the maximum sustainable yield that can be cropped from a fishery comes when the biomass of a target species is about 50% of its original levels.
经6次传代培养后，其生物量和菌丝多糖产量较稳定，且明显超过原始菌株，表明其遗传稳定性良好。
After continuous cultivation for 6 generations, the biology yield and the polysaccharide yield were steady and obviously exceeded the original strain. It showed a good genetic stability.
