Abstract

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.
