Monoculture of climbing perch, Thai koi, Anabas testudineus (Bloch) under different stocking densities at on-farm

An on-farm trial was undertaken in nine earthen ponds (400 to 640m2) to evaluate the growth and production potentials of climbing perch, Thai koi (Anabas testudineus) for the period of four months from March through June 2006. Three stocking densities such as 75,000 (T1), 100,500 (T2) and 125,000/ha (T3) were tested with three replications. Fish were fed with commercial (SABINCO) pelleted feed (35% crude protein). Fish productions obtained in three treatments such as T1, T2 and T3 were 6,480±217, 6,384±154, 6,617±187 kg· 1ha, respectively. The results demonstrated higher mean growth in T1 than in T2 and T3. However, the net benefit was achieved Tk. 7,26,975 from T1, where the stocking density was 75,000/ha.
