Supplementation of seablite (Suaeda maritima) extracts in sea bass (Lates calcarifer) diet

Abstract

Feeding experiments of 1.84 ± 0.08 g Lates calcarifer with diets containing of the leave extract
of Suaeda maritima at 0, 5, 10 and 20 g/kg diet for 8 weeks. The results showed that the fish fed with the
different concentrations of leave extract had statistical difference (P <0.05) on final weight and weight
gain. The maximum final weight and weight gain were found in fish fed by 10 g / kg diet
supplementation of S. maritima extract (31.98 ± 1.07 and 31.09 ± 1.06 g /ind, respectively), with No
statistically differences (P> 0.05) on survival rate of the fish. After four weeks of trial feed, the fish that eat
S. maritima extract 20 g / kg diet showed hematocrit 22.25 ± 3.23%, which was less than the other treatments
by statistical difference (P <0.05). No statistical differences (P> 0.05) in number of red blood cells
and white blood cells and also no differences (P> 0.05) on type of white blood cell except eosinophils
and neutrophils were found. At the end of the experiment, after eight weeks there were no statistical
differences on hematology (P> 0.05) between all of treatments.
