Effect of high and low cost brood feeds on gonado-somatic index and fecundity of freshwater prawn Macrobrachium rogenbergii de Man
Studies were conducted to observe the effects of different types of feeds on thegonado-somatic index (GSI) and fecundity of freshwater prawn Macrobrachiumrogenbergii. Three different treatments (T1 T2 and T3) were designed with threetypes of feed as follows: (i) Saudi-Bangla Prawn feed 100% - T1 (ii) SaudiBanglaprawn feed 50%+ local feed 50%- T2 and (iii) local feed 100%- T3. Theresults showed that the average value of gonado-somatic index (GSI) was 14.39,14.35 and 14.36 and the average fecundity of M. rogenbergiiwas 99,741, 98,125and 97,911 in T1 T2 and T3 respectively. No significant difference (p>00.5) wasbetween gonado-somatic indices (GSI) and fecundities of M. rogenbergii amongdifferent feeding trails. The price of Saudi-Bangla prawn feed was very high(Tk. 23/kg) than the local feed (Tk. 14/kg). So, use of local feed wasrecommended for M. rogenbergii brood rearing.
