Abstract
The study was conducted to understand the effects of spirulina and probiotic on the growth performance of Shing (Heteropneutes fossilis) at laboratory condition in Hajee Mohammad Danesh Science and Technology University. The research was designed of two treatments (T1: use of artificial diet; T2: artificial diet with spirulina and probiotic) with two replications and was performed from 1 October 2018 to 31 December 2018. Water quality parameters were regularly monitored. Fish growth was measured prior stocking and after the trial. Results indicated that water quality did not show significant (P˃ 0.05) changes between the treatments during the study period. Fish growth was attributed by higher length gain (LG: 2.35 ± 0.20 cm) and weight gain (WG: 3.10 ± 0.26 gm) in T2 than T1 (LG: 1.22 ± 0.11 cm; WG: 2.365 ± 0.21 gm). Higher specific growth rate was found in T2 (0.34%) than T1 (0.28%). Low food conversion was determined in T2 (6.83) than in T1 (16.09) after the trial. This indicates the better effects of spirulina and probiotic on growth of shing in T2. However, condition factor of fish indicated good and healthy condition in both treatments. Overall, the results show that spirulina and probiotic is likely having significant role in the growth of shing in experimental condition. This study enhanced our understanding and knowledge on effects of probiotics and spirulina as supplementary diet of shing.
