The results indicated that marine fishes were richer in sodium (155.7 to 346.4 mg) and calcium (89.0 to 376.5 mg) than freshwater fishes (sodium, 48.2 to 124.8 mg; calcium, 4.4 to 233.0 mg per 100 g edible portion). However, potassium content was found higher (228.4 to 500.8 mg) in freshwater fishes as compared to marine fishes (180.0 to 260.6 mg). In the case of magnesium, iron, and zinc, the values were not so much different between freshwater and marine fishes, although variation in values among the fishes of some species was high in the case of freshwater fishes (magnesium: 1.80 to 53.06 mg in freshwater fishes and 31.2 to 40.7 mg in marine fishes); iron: negligible to 3.22 mg in freshwater fishes and 0.85 to 2.22 mg in marine fishes; zinc: 0.21 to 4.53 mg in freshwater fishes and 0.74 to 2.25 mg in marine fishes.
