      abstract = {The effects of mola (Amblypharyngodon mola) at different  densities in polyculture with freshwater  prawn
(Macrobrachium rosenbergii) were investigated at the  Fisheries Field Laboratory, Bangladesh Agricultural  University,
Mymensingh. The experiment had three  treatments, viz. prawn + 1 mola m-2, prawn + 1.5 mola m-2  and prawn + 2
mola m-2 and were treated as T1, T2, and T3,  respectively with three replications in each. Prawn  stocking density was
same (3 juvenile m-2) in all  treatments. Feeds were applied twice daily for prawn.  Assuming 80% survival, feeding
rates were gradually reduced  to 10-5% of body weight from the beginning to the last  month. Water quality parameters
(except transparency,  chlorophyll-a) did not vary significantly (P>0.05). Weight  gain, SGR (% body weight), gross and
net production of  prawn were not significantly different (P>0.05). Higher  total production was recorded in T3 (574.61
±39.58 kg ha-1)  followed by TI (531.65±42.40 kg ha-1) and T2 (514.75±77.91  kg ha-1). It was found that addition of
mola at different  densities had no effects on survival and production  performance of prawn. Therefore, nutrient-dense
mola may be  stocked as an additional species with freshwater prawn. It  might be concluded that treatment T3 was
better proposition  for prawn-mola polyculture.},
