The objectives of this work were to study the feeding attractant supplementation’s effects on mullet (Mugil cephalus) growth and digestive enzyme activities, in the light of feeding them fish meal replaced partially by defatted soybean meal (25% of fish meal protein). The diets given to the tested mullets contained four inclusion levels of feeding attractant, separately, 0, 1, 1.5, 3.0 and 4.5%. The mullet reared on the attractant supplement diets for 7 weeks showed enhanced weight gain, total intake and feed efficiency, especially to the 4.5% group. The feed efficiency of the 4.5% group was significantly higher than the group without attractant diets (P < 0.05). The one got more improvement on growth than what the other did. And the effective quantity to stimulate feed intake is 3.0%. Also, the enzyme activities of protease, lipase and amylase in the supplemental group were higher than those of the non-supplemental group. The supplemental group, meanwhile, showed significantly higher alkaline protease and neutral protease activities in digestive tract than the group without attractant supplement (P < 0.05)
