Table 4.

Weight gain, length gain and specific growth rate (SGR) of Atlantic salmon (Salmo salar) fed with experimental diets (low dose oral vaccine, high dose oral vaccine, injectable vaccine).

Group	Weight Gain (grams)	Length Gain (cm)	SGR (%/day)
Low dose	44.12 ± 5.59 a	4.77 ± 0.36 a	1.37 ± 0.12 a
High dose	47.93 ± 7.40 a	5.48 ± 0.73 a	1.42 ± 0.17 a
Injectable vaccine	44.20 ± 8.45 a	4.78 ± 0.77 a	1. 35 ± 0.20 a
p-value	0.706	0.219 1	0.816

Different lowercase letters in a column indicate significant differences (p ≤ 0.05) among the different experimental groups (low dose, high dose, injectable vaccine). ¹ Non-parametric Kruskal–Wallis test was applied to evaluate differences in length gain.
