“…There is reported overexploitation of V. litterata in the country due to demand for protein food resulting to a low population in its natural habitats (Subang et al 2020). The natural habitats of other edible crabs are also subjected to ecological disturbances and polluted environments due to anthropogenic activities (Nelson et al 2015;Pati et al 2017;Yogeshwaran et al 2020).…”

Abstract. Jumawan JH, Ruales JJJ, Avila MCA. 2022. New distribution record of Varuna litterata from Caraga Region, Philippines: Analysis on morphometry, length/width-weight relationship, and condition factor. Biodiversitas 23: 2935-2942. The study reported the occurrence of Varuna litterata in its habitat as a new record in Caraga Region, Philippines. The crab samples were collected using a hand-picked method and were of marketable sizes. There were 14 morphometric traits measured with the corresponding weight and sex of each specimen. Majority of the crab samples were medium-sized, with weight ranging from 11-20 grams, a carapace width range of 28-34 cm, and a carapace length range of 27-32 cm. Exploratory analysis of length /width-weight data fits the power regression model depicted into graphs. A strong relationship and highly significant was observed on pooled samples of WT-CW variables (R2: 0.9229: P<0.001) and WT-CL variables (R2: 0.9197); P<0.001). The derived log-transformed for WT-CW relationship was logWT: -2.7994+2.6456 logCW. Results suggest that carapace length and width tend to be smaller relative to the weight, which is an indication of a negative allometric growth pattern. The computed Fulton's condition factor was higher in males than females, as supported by Kruskal Wallis test (P<0.001). The data provides baseline information for comparing similar studies and in understanding the population dynamics of this crab species.
