Influence of dietary β-glucan on length-weight relationship, condition factor and relative weight of pompano fish (Trachinotus ovatus, family carangidae)


Author(s): Do-Huu Hoang

Abstract: The present research examined the effects of dietary β-glucan concentrations (Diet1: 0%, Diet 2: 0.1%, Diet 3: 0.2% and Diet 4: 0.4%) on length-weight relationship, condition factor and relative weight of pompano fish (Trachinotus ovatus). Fourteen fish (mean initial weight, 6.46 g; mean initial length, 62.59 mm) were randomly stocked in each tank with six replicates for each diet. After 56 days, the growth rate was significantly higher in fish fed Diet 2. Folk lengths and weights were measured and data were analyzed using logarithm transform linear equation of Log W = Log a + b Log L. Growth parameters were isometrically in fish fed Diets 2, 3 and 4 with b values were 3.107, 3.078 and 2.969, respectively, however, fish fed Diet 1 had a negative allometric growth (b = 2.672). The correlation coefficient (r) was high in all treated groups (r ≥ 0.898, P ≤ 0.001). Condition factors (K) ranges from 3.13 to 3.18 with the highest K value was in fish fed Diet 2, significantly higher than fish fed Diet 1 (P = 0.001). It is recommended to include 0.1% β-glucan in the diet to boost growth and condition factor of pompano fish, T. ovatus.
