Growth and production performance of Vietnamese climbing perch (Anabas testudineus) at farm level in Jashore, Bangladesh

Abstract

The experiment was carried out to assess the effects of stocking density and
management practices on the growth and production performance of exotic climbing perch
locally known as Vietnamese koi (Anabas testudineus). The monoculture of Vietnamese koi was
done from March to June 2017 in 213.33±63.94 m2 earthen ponds located in Jashore district,
Bangladesh. Fingerlings of 2.44±0.04cm total length and 0.22±0.01g weight were stocked at a
rate of 22 fingerlings/m2 in treatment T1, 55 fingerlings/ m2 in treatment T2 and T3. Supplemental
feed (30% protein) was applied at the rate of 3-10% of body weight in T1 and T2 while in T3 fish
were fed as practiced by the farmers. After 120 days of culture, the survival rate was estimated at
84.73±16.86%, 64.12±6.36% and 63.50±25.14 for T1, T2 and T3, respectively. The average
final body weight of the fish was 72.67±6.03 g in T1, 53.39±3.49 g in T2 and 52.55±14.12 g in
T3. The SGR in treatment T1(4.83±0.07) was higher than T2 (4.58±0.05) and T3(4.55±0.23).
While, the FCR was comparatively higher in treatment T3 (1.80±1.15) than T2(1.75±0.14) and
T1(1.50±0.67). The productionwas estimated at 13,338kg/ha, 18,574.40 kg/ha and 18,179.20
kg/ha in T1, T2 and T3 respectively. The highest net return was estimated in T1 (Tk.
3,55,877.60/ha) followed by T2 (Tk. 2,78,122/ha) and T3 (Tk. 2,56,880/ha), respectively. The
BCR was calculated 1.32 for T1, 1.16 for T2 and 1.15 for T3. The stocking number 22/m2 of
Vietnamese koi and good management practices might be helpful for enhanced and sustainable
production of Vietnamese koi in the region.
