生物量的估算对于模拟生态系统中的结构、动物生长、生产和能量流的研究至关重要。研究了两个不同种群中两种螯蟹的干重与甲壳宽度的关系。长度-重量样地在种、性别和种群间的分布差异不显著。我们的研究结果表明，无论性别或种群或包括多个物种，长度-重量关系都是有效的干重估计。
Estimates of biomass are essential for studies modeling the structure, animal growth, production, and energy flow in ecosystems. The relationships between dry weight and carapace width of two varunid crab species in two different populations were examined. Distribution of the length-weight plots did not show remarkable differences between species, sexes, and populations. Our results suggest that length-weight relationships, regardless of sex or population or including multiple species, are valid for estimation of dry weight.
