Effects of high and low cast feed on the hatching and survival rate of freshwater prawn Macrobrachium rogenbergii larvae were observed. Three different treatments (T1, T2 and T3) were designed with three types of feeds as follows: T1, Saudi-Bangla Prawn feed 100%; T2,Saudi-Bangla prawn feed 50% + low cast feed 50%; T3, low cast feed 100%. The prawns were reared from February to May 2001 until they became mature enough to breed. The results showed that the average value of hatching rate was 90.14%, 89.69% and 89.29% and the average survival rate of larvae was 39.44%, 38.88% and 38.33% in Tl, T2 and T3 respectively. There were no significant differences (P>0.05) between hatching and survival rate of M. rogenbergii from different feeding trails. The price of Saudi-Bangla prawn feed was very high (Tk. 24/kg) than the local feed (Tk. 14/kg). So, use of local feed was recommended for M. rogenbergii brood rearing.
