Effects of dietary crude fiber level on growth performance, body composition, liver glycogen and intestinal short chain fatty acids of a tropical carp (Barbonymus gonionotus♀ X Hypsibarbus wetmorei male ♂)

Aim : A 60-day feeding trial was conducted to determine the maximum dietary crude fiber level a tropical carp, lemon fin barb hybrid, could tolerate in theirdiet. Methodology: Twenty fish (1.50 ± 0.05 g) were randomly stocked per 1001 aquarium tank in 3 replicates and fed twice a day with 5 isonitrogenous (30% protein), isocaloric (17 kJ g-1), 35% carbohydrate and isolipidic (4%) testdiets containing 0,5,10,15 and 20% crude fiber until apparent satiation. Results : The survival (100%) was unaffected by the dietary fiber level although weight gain, specific growth rate, and protein efficiency ratio significantly decreased (p
