Abstract：The nutritional composition between Paracobitis anguillioides and Misgurnus anguillicaudatus was compared.The results showed that the skin of Paracobitis anguillioides and Misgurnus anguillicaudatus con-tained lower water contents (-1 3.03%,P<0.05;-1 0.30%,P<0.05 )but higher protein contents (+54.22%,P<0.05;+9.60%,P<0.05)when compared with those in muscle.Moreover,the skin of both Paracobitis anguillioides and Misgurnus anguillicaudatus possessed abundant levels of collagen when com-pared with those in muscle (61 .76 mg/g vs.5 .75 mg/g).No evident differences in amino acid composition were obtained between Paracobitis anguillioides and Misgurnus anguillicaudatus.In addition,the first limiting amino acids in muscle of Paracobitis anguillioides and Misgurnus anguillicaudatus were valine,while the first limiting amino acids in skin were threonine and methionine+cystine,respectively.Higher contents of total fat and polyunsaturated fatty acids were found in muscle of Paracobitis anguillioides and Misgurnus anguillicauda-tus than those in skin (P<0.05),revealing significant differences between Paracobitis anguillioides and Mis-gurnus anguillicaudatus (P<0.05).As for the minerals,the muscle of Paracobitis anguillioides and Misgur-nus anguillicaudatus enriched in potassium,2 687.36 mg/kg and 1 750.49 mg/kg,respectively.Neverthe-less,the skins had abundant contents of calcium,up to 4 091 .83 mg/kg and 5 948.43 mg/kg,respectively.
