The biochemical composition in wild long-snouted female and male individuals of Hippocampus guttulatus was investigated in Southeastern Black Sea. PUFA were the most important fatty acids in males (40%) and in females (41%). The main components of PUFA were DHA (20-22%) and EPA (9-11%). DHA was the most abundant fatty acids in H. guttulatus. Cholesterol was the most important sterol in the males and females (205.36 µg/g; 200.36 µg/g, respectively). α- tocopherols (vitamin E) was the most important lipophilic vitamins and α-tocopherol acetate was the highest amount (6.67 µg/g; 7.88 µg/g, respectively) in the females and males. Total protein was 13.87 mg/g in the male and 14.38 mg/g in the females. GSH (Glutathione) and GSSG (Oxidised Glutathione) levels were lower than MDA (Malondialdehyde). GSH was 99.66 µg/g in the male and 98.18 µg/g in the female. GSSG was 40.25 µg/g in the males and 40.18 µg/g in the females. It was thought that high MDA level (251.07-256.30 µg/g) occurred, because low vitamin E level did not prevent PUFA peroxidation. Our findings showed that biochemical composition of seahorses did not differ between male and female individuals except for fatty acids (p<0.01).
