Sialic acid, nutritional and fatty acid compositions of three species of freshwater fish eggs

Abstract

This research aimed to determine the nutritional, sialic acid (SA) and fatty acid compositions of red hybrid tilapia (Oreochromis sp.), snakehead murrel (Channa striata), and sutchi catfish (Pangasius hypophthalmus) fish eggs. Eggs of P. hypophthalmus had the highest moisture (60.58%), ash (1.68%) and protein (25.19%) content while C. striata had the lowest moisture (48.58%), ash (0.81%) and protein (13.08%) content. Lipid content of C. striata fish eggs (35.94%) was significantly higher (p 0.05) of polyunsaturated fatty acid composition among three selected freshwater fish eggs. This study revealed that all selected freshwater fish eggs can be a source of major nutrients, SA and essential fatty acids.
