Preliminary observations on the plasma composition of liza klunzingeri from the strait of Hormuz (Persian gulf)

Abstract

Serum biochemistry can be used for monitoring changes in the physiological condition of fish and water quality. The aim of this paper was to determine the concentrations of plasma T3 (Thyroid hormone), thyroxin, TSH (Thyroidstimulating hormone), ALT (Alanine Aminotransferase), AST (Aspartate aminotransferase) and cholesterol of Liza klunzingeri caught on the northern side of the strait of Hormuz (Persian Gulf). Biochemical values were: T3 0.96 ± 0.58 ng/ml, Thyroxin 76.58 ± 28.26 ng/ml TSH 0.03 ± 0.01 nmol/L, ALT 1.71 ± 0.68 U/L, AST 49.81 ± 5.25 U/L and cholesterol 177.28 ±40.75 mg/di. A significant positive correlation (P < 0.01) was found between AST and Cholesterol. ALT had a significant and positive correlation with cholesterol and AST (P < 0.01). Thyroxin also had a significant and positive correlation with cholesterol (P < 0.01) and AST (P < 0.01). The results revealed negative correlation between Thyroxin with TSH (P < 0.01). This study provides the first data on this blood chemistry of L. klunzingeri. © 2013 Mohammadizadeh et al.
