Abstract
Macrobrachium idae juveniles (0.9 - 1.3 g) were fed on eight formulated diets containing
32-42% crude protein to assess their growth performance. Prawns fed on groundnut oil cake
meal (GOC) and soybean meal (SBM) showed the best growth rate (SGR) (0.46 and
0.43%.day"1, respectively), food conversion ratio (FCR) (2.16 and 2.53, respectively) and protein
efficiency ratio (PER) (0.84 and 0.78, respectively). Hydrilla verticellata (HV) and drumstick
leaves (DRM) diets resulted in poor growth and decreased PER and SGR with elevated FCR.
The efficiency of absorption and net conversion ranged between 84-90% and 3.81-7.8%,
respectively. Increase in dietary protein content (3-8%) produced elevated growth rates and
protein efficiency ratio. The dietary protein-energy ratio for maximum growth of prawns was
97.2 mg.kcal"1 with a digestible energy of 431 kcal.lOOg"1 of feed
