The second feeding trial was conducted using 12 outdoor concrete tank (2.5x2.0x1.1 m3)for 15 weeks. one hundred fingerlings with average size of 0.69 g. were stocked in each tank. The highest weight gain and specific growth rate were observed in fish fed the diet with 15 % prawn meal. feed conversion ratio were not significantly different among treatment (p>0.05) However, mortality of fish fed with prawn meal treatment was higher than the fish fed with control diet. The results suggested that the dietary inclusion of 15 % of prawn meal promoted feed acceptability, feed intake and improve growth performance of marble goby, However, further studies are needed to investigate on the low survival rate of fish fed with 15 % prawn meal containing diet and also to develop commercial feed for marble goby.
