Inulin Supplementation in Diets for Tropical Gar (Atractosteus tropicus) Larvae: Effects on Growth, Survival, and Digestive and Antioxidant Enzyme Activities

The effect of adding inulin to balanced diets for tropical gar (Atractosteus tropicus) larvae on growth, survival, digestive enzyme activity, and antioxidant activity was evaluated. were supplemented with 0.5, 1.0, 1.5, 2.0, 2.5% in addition a control diet (0% inulin). A total 1800 A. tropicus distributed 18 tanks used; the fed five times day (8:00, 11:00, 13:00, 15:00, 18:00) Artemia nauplii from absorption yolk (from 3–7 days after hatching, DAH) up 10 DAH, which mixed experimental feeds 8–11 DAH (co-feeding) exclusively 12 21 DAH. Larvae inulin) had highest growth weight length, followed by fish 2.5 2.0% inclusions. However, survival showed that inclusion percentage (34.7%) compared rest treatments. On other hand, enzymatic activities (acid alkaline proteases, amylase, lipase) recorded 2 inulin. Likewise, catalase (CAT) superoxide dismutase (SOD) higher 0% Supplementation is recommended as it improves during this early stage life.
