Proximate compositions of wild and cultured sweet smelt (Plecoglossus altivelis) muscles and eggs

Proximate compositions of muscles and eggs between wild sweet smelt which were caught in Seomjin river and Miryang river, and cultured sweet smelt which were purchased from certain cultured farms in Hadong and Miryang, were compared. Proximate compositions of wild sweet smelt muscles were for moisture, for protein, for lipid, and for ash content and there were almost no differences between the fishes from Seomjin and Miryang river. Protein and ash content in the cultured fish muscles were similar to those of the wild fish muscles, while the former contained much more lipid and carbohydrate, and less moisture than the latter, especially lipid content differed greatly according to their cultured farms. This might be the result of their different diet compositions. Lipid, protein and carbohydrate content in eggs of the wild and cultured fishes were much higher than those in their muscles. There was a negative correlation between moisture and lipid content in all samples; y= -0.2715x+24.903 (r= -0.7253, p
