Table 2 Survival (%), weight gain (g/abalone) and specific growth rate (SGR) of juvenile abalone fed the experimental diets substituting Undaria with the dry white radish’ by-product (WRB) and tunic of sea squirt (TSS) for 16 weeks

From: Substitution effect of white radish (Raphanus sativus L.)’ by-product and tunic of sea squirt (Halocynthia rorentzi, von Drasche) for Undaria pinnatifida in feed of abalone (Haliotis discus, Reeve 1846)

  1. Values (means of triplicate ± SE) in the same column sharing the same superscript letter are not significantly different (P > 0.05)
  2. aSpecific growth rate (SGR, %/day) = [(Ln(Wf) − Ln(Wi))/days of feeding] × 100, where Ln(Wf) = natural log of the final mean weight of abalone and Ln(Wi) = natural log of the initial mean weight of abalone
