FCR ranged from 2.65 to 2.93, the lowest value 2.65 was observed in T1 and the highest value 2.93 was observed in T4. Christensen(1994) reported that FCR of tinfold barb(Puntius schwanenfeldii) was 2.8 when fish were fed pellet feed in floating cages which agrees with the results of the present experiment. Hasan et al (2010) found the FCR value of Thai climbing perch reared in nylon hapas ranged from 3.31 to 3.99 ,which was higher than the present study. It might be due to the use of low quality pellet feed. Osofero et al (2009) reported FCR of 1.56 to 2.21 for tilapia (O.niloticus) during 91 days culture in cages. Mondal et al (2010) Observed in FCR caged tilapia was 0.79 after 120 days culture. In the present study, FCR of Thai climbing perch culture in cages was very much higher than tilapia culture in cages.
