Effect of seaweed supplemented diets on Nile tilapia, Oreochromis niloticus performance


Author(s): Ebtehal EL-Sayed M Hussein

Abstract: In the present study the effects of the seaweed Taonia atomaria supplementation in diets for Nile tilapia were investigated. A 12-week feeding trial was carried out using triplicate groups of Nile tilapia, Oreochromis niloticus with 1.1±0.04 g initial weight. Four experimental diets were formulated and marked as D1 (control), D2, D3, and D4. There were significant differences (P<0.05) on growth performances among dietary treatments. The growth of the fish fed control diet showed higher FI compared to other treatments (P<0.05). Significant differences (P<0.05), were however shown in lipid and ash contents. Somatic indexes in terms of HSI and VSI differed significantly (P<0.05) by the inclusion of seaweed. No diet related histopathological changes were noted in intestine and/or liver samples from any dietary groups. Seaweed can be supplemented to diets for Nile tilapia up to 5% without any adverse effect or abnormalities of fish tissues.
