ABSTRACT
The objectives of this study were to describe the length-weight relationships (LWRs), and condition factors of P. conchonius collected from the Atari River in Dinajpur, Bangladesh. A total of 1746 male and female individuals were captured where length as 4.2-8.1 cm and weight as 1.0-8.7 g was recorded. In LLRs (among TL, SL, HL and FL), strong relationships were found of TL vs. SL (r2 > 0.003), TL vs. FL (r2 > 0.006), FL vs. SL (r2 > 0.001), HL vs. TL (r2 > 0.016), HL vs. SL (r2 > 0.005) and HL vs. FL (r2 > 0.009) between sexes of this species. Condition factors were recorded such as Fulton’s condition factor (CFf) as 1.08-2.10 and 1.17-2.11, relative body weight (BWr) as 73.99-126.88 and 68.60-126.18, and foam factor ranged from 0.0001 to 0.089 and 0.0004 to 0.046 for female and male, respectively. Lastly, it may be concluded that the findings of this research on P. conchonius would be baseline information for future research and management of this species.
