Table 2 Growth performance of shrimp fed a variety of experimental diets

From: Excess dietary cholesterol may have an adverse effect on growth performance of early post-larval Litopenaeus vannamei

Cholesterol levels, % D10 D20.5 D31 D42 One way ANOVA (P value)

  1. Values are shown as mean ± SE of three replicates. Means within the same row and not sharing a common superscript are significantly different (Ducans, P < 0.05); ns, no significant difference detected (P > 0.05).
  2. IBW (mg/shrimp): Initial body wet weight (mg/shrimp).
  3. FBW (mg/shrimp): Final body wet weight (mg/shrimp).
  4. WG (%): weight gain = 100 × (final body weight- initial body weight)/initial body weight.
  5. SGR (%/day): specific growth rate = 100 × (ln final wt.- ln initial wt.)/total number of experimental days.
  6. Survival (%) = 100 × (final shrimp number)/(initial shrimp number).
