An experiment with salinities of freshwater (control), 6, 9 and 12 gL-1 was conducted for 8 weeks. 250 prawn juveniles with an initial average weight of 1.5±0.44g randomly distributed between 15 glass aquaria of 100 liters. With increasing salinity levels up to gL-1, the growth performance and blood biochemicals including cortisol and glucose showed no improvment and had significant differences with other treatments (P<0.05). Growth parameters such as BWI(%) and SGR in control treatment (0 gL-1) comparing with 6 gL-1 were relatively increased without showing any significant differences (P>0.05). However, the FER and SR in T1, T2, T3 and T4 (0, 6, 9 and 12 gL-1) showed no significant difference (P>0.05). Some hemolymph biochemicals including cortisol and glucose were increased in T5 (16 gL-1) and the improvement was not observed (P<0.05). This study indicated that the reared prawns have relatively better performance in freshwater. %U https://japb.guilan.ac.ir/article_3209_b66f7ad444df536b4306003774370e52.pdf
