Table 1 Growth performances and feed utilization of the Oncorhynchus mykiss fed with different diets: Diet 1 (Negative control with normal diet), Diet 2 (normal diet add with 3% Bacillus sp. GFP-2)

From: Isolation and characterization of Bacillus sp. GFP-2, a novel Bacillus strain with antimicrobial activities, from Whitespotted bamboo shark intestine

  Diet 1 Diet 2
Initial weight (g) 300 300
Final weight (g) 631 1442
Gained weight (g) 331 1142
Specific growth rate (%) 11.03 38.07
Feed conversion ratio 1.27 0.37
Survival rate (%) 29.80 79.00
  1. Final weight and Initial weight were calculated in average; Gained weight = Final weight (g) − Initial weight (g); Specific growth rate = 100* (ln Final weight − ln Initial weight)/Duration of experiment (60 days); Feed conversion ratio = feed given (dried weight)/Gained weight (wet weight); Survival rate (%) = (final fish number/initial fish number) *100
