| dc.description.abstract | This thesis titled "Comparative study on the effect of different sheds on growth performance of Vietnam koi (Anabas testudineus Linn.) in Biofloc system" aimed to compare the effectiveness of two biofloc systems (with green net and tin shed) in maintaining water quality parameters for successful Vietnam koi fish culture. The study was conducted from June 2022 to December 2022 for six months, comparing the average weight and length gain, survival rate, specific growth rate (SGR), and water quality parameters between the two systems. The study found that both systems were effective in maintaining water quality parameters, but the green net shed biofloc system showed better results in terms of fish growth (110.16 g), nitrite (0.20 mgL-1), floc volume (27.76 mlL-1), alkalinity (208.07 mgL-1), and maintenance of optimum temperature (28.740C). A. testudineus reared under the green net shed biofloc system had significantly higher daily weight gain (0.99 g) and lower feed conversion ratio (1.05) than those under the tin shed biofloc system. The specific growth rate (SGR) was not significantly different between the two systems (1.79 g and 1.69 g for green net and tin shed respectively). The study observed that ammonia levels were higher (0.31 mgL-1) in the tin shed than green net shed (0.27 mgL-1) biofloc system and was within the acceptable range for Vietnam koi farming. The results of this study suggest that the green net shed biofloc system is a better option for successful Vietnam koi fish culture in terms of growth performance and water quality parameters. | |
