The condition factor of a small indigenous freshwater prawn, Macrobrachium lamarrei (H. Milne-Edwards, 1837) was studied to evaluate the health status of the species sample over a calendar year. A total of 1018 specimens (485 males and 533 females prawn) were used in this study, where condition factor for male, female and combined prawn varied with months. In case of male, the highest condition index was found in June (1.141) and lowest was found in August (0.886), and for female, the highest condition index was obtained in May (1.221), and the lowest was in July (0.947). In the combined sex, the highest condition index was determined in June (1.235), and lowest value was in September (0.966). The study suggested that both male and female individuals of the prawn population M. lamarrei were fatty in May and June; on the other hand, they appeared in lean condition in July and August over a calendar year.

Key words: Condition factor, freshwater prawn, Macrobrachium lamarrei, Bangladesh
