The freshwater crabs were collected from the Padma river near the Rajshahi district of Bangladesh during May, 2015 to October, 2015 to investigate its morphology and proximate composition. The present study showed that the available range of the body weight (BW) was 6-10 g; carapace width (CW) 26-30 mm; carapace length (CL) 21-25 mm; abdomen width (AW) 11-15 mm and abdomen length 11-15 mm. The sex ratio was varied from month to month and overall sex ratio was found 1:1.68. The sex ratio was uneven in most size groups and in most of the months. The chi-square (χ2 ) value was significant for P. lamellifrons. T-test shows the difference between male and female crab. The present study was also conducted to evaluate the proximate composition of P. lamellifrons. Total body parts of crabs were cut into three fragments (cephalothorax, cheliped and legs) and their proximate composition were analyzed using instrumental technique. In the present study proximate composition moisture, protein, fat, ash and cholesterol were ranges from (56.01-68.92)%, (34.23-34.46)%, (0.53-9.34)%, (9.54-18.05)% (0.06137-0.2168)% respectively. Among the different body parts of the collected freshwater crab cephalothorax contents highest amount of moisture, protein, fat and cholesterol compared to cheliped and legs whereas, cheliped contain highest amount of ash than cephalothorax and legs. Except ash, amount of moisture, protein, fat and cholesterol were observed in the different body parts of the investigated crab in the following order Cephalothorax>Cheliped>Legs. Present investigation results revealed the presence of essential nutrient specially protein in the all body parts of the crab.
