Abstract

In this study, the quality of fatty acids in sturgeon caviar were assessed and compared in rearedand wild specimens of beluga, Huso huso caught from the Caspian Sea. The fatty acids profile, n3/n6 and atherogenic and thrombogenic index were also measured. The wild caviar had higher PUFA and n3/n6 than reared fish (P<0.05). The EPA + DHA content in wild caviar (20.7) was significantly higher than reared specimens (10.54) (P<0.05). Atherogenic index in wild (0.33) was significantly higher than reared (0.27), while thrombogenic index in reared was higher than wild (P<0.05). The results obtained from the present study show that the reared beluga caviar has a good quality and is a suitable alternative for wild caviar.
