N2 - Measuring individual body length and weight is a basic procedure in fisheries scientific studies. The length-weight relationship (LWR) is a useful tool to predict the weight at a certain length (and vice versa), analyze condition indices, and estimate the biomass of the fishery resources. The objectives of this study were to determine the LWRs, sex ratio and condition factors (K) of Scylla paramamosain from Brantas Estuary, East Java, Indonesia. Crab samples were caught using the traditional crab net of local fishers. Carapace width (cm) and body weight (g) were measured to the nearest 0.01 cm and 0.01 g, using a digital caliper and digital analytical balance, respectively. The sex ratio of male:female S. paramamosain was 1.01:1, which not significantly different from the expected 1:1 value. The carapace width of males and females S. paramamosain ranged from 7.08 cm to 11.23 cm and 5.36 cm to 13.20 cm respectively. The weight of male and female S. paramamosain ranged from 6.11 g to 31.69 g and 5.69 g to 35.69 g respectively. The b value of males, females and total individuals were 3.23, 2.59, and 2.71, respectively. The condition factor for males and females ranged from 1.52 to 2.42 and 1.38 to 2.32 respectively.
