Determination of nutritional composition of some selected fishes from hel river of North-East India

Abstract

In this study, proximate composition and mineral contents of ten fish species viz. Barilius bendelisis, Chagunius chagunio, Garra gotyla, Labeo pangusia, Neolissochilus hexagonolepis, Raiamas bola, Tor putitora, Cyprinion semiplotum, Barilius barna and Psilorhynchus nudithoracicus from Hel river of North-East India were investigated and all the results were presented per 100 g of dry weight basis. The moisture content was found in the range of 5.44 ± 2.20 g to 8.87 ± 1.46 g. Ash content varied from 1.28 ± 0.017 g in B. barna to 3.20 ± 0.012 g in N. hexagonolepis. The crude protein content was found highest in G. gotyla (29.33 ± 0.249 g) and the lowest in R. bola (21.91 ± 0.012 g), and crude fat was found to be lowest in B. barna (13.51 ± 0.010 g) and highest being in C. semiplotum (29.85 ± 0.010 g). Total carbohydrate was found in the range of 38.55 ± 0.21 g to 53.92 ± 0.57 g, and the lowest nutritive value was obtained in C. chagunio (426.95 ± 4.53 kcal/100 g) and the highest nutritive value being in C. semiplotum (521.38 ± 9.23 kcal/100 g). The highest level of iron was detected in C. chagunio (21.89 ± 0.029 mg) and lowest in B. barna (5.56 ± 0.071 mg). The highest amount of copper was observed in N. hexagonolepis (2.91 ± 0.029 mg) and the lowest in R. bola (0.523 ± 0.034 mg). The magnesium, calcium and zinc levels varied from 0.14 ± 0.006 to 0.31 ± 0.017 mg, 0.30 ± 0.012 to 0.64 ± 0.020 mg and 1.06 ± 0.044 to 4.51 ± 0.029 mg, respectively. It can be concluded that the fish species selected for this study could be good sources of proteins, fats, minerals and high nutritive value for human consumption.
