Abstract to achieve marketable size ( 30 g) in the limited growing season available in temperate areas, post-larval freshwater prawn, macrobrachium rosenbergii must be grown to a larger size (from 001 to 02 g) prior to pond stocking this is known as the nursery phase little research has been conducted on the effects of different management and environmental factors on juvenile prawn.
The giant freshwater prawn, macrobrachium rosenbergii, is a species with a high commercial value in aquaculture two experiments were performed to determine the effects of salinities on the osmoregulation, growth and molting cycles of m rosenbergii during growout. The investigation indicated that m rosenbergii growth, survival rate and feed intake was slightly better with experimental diet 1 containing 445 % fish meal, 50 % copra meal, 50 % pea meal, 435 % wheat and 20 % vitamin-mineral premix.
