Proximate and mineral composition of some commercially important fish species of tekeze reservoir and lake Hashenge, Ethiopia


Author(s): Tsegay Teame, P Natarajan, Zelealem Tesfay

Abstract: The aim of the present study was to estimate the chemical composition (crude protein, crude fat, ash, moisture and carbohydrate) and mineral contents (K, Ca, Na, Mg, P, Zn, Fe, Cu and Mn) in five fish species from the Tekeze reservoir and Lake Hashenge. Samples of fishes were collected from Tekeze reservoir and Lake Hashenge between December 2014 and March 2015 from the landing sites of the two water bodies. The samples were immediately and fish fillets were stored in refrigerator to determine the proximate and mineral contents of the fillet using the standard procedures of AOAC (2000). The result of the proximate composition analysis showed that the content of the crude protein of Cyprinus carpio, Clarias gariepinus, Bagrus docmak, Labeobarbus intermedius and Labeobarbus nedgia was 17.25%, 15.44%, 15.35%, 14.98% and 15.09% of the wet weight, respectively. The analyzed result showed that the content of moisture, Crude protein, crude fat and carbohydrate value of the different fish species were significantly different (P<0.05). The percentage of ash between the sampled fish species were not significantly different (P>0.05). The content of crude fat and ash were ranged from 1.26 to 5.74% and 0.83 to 0.94% of the wet weight, correspondingly. The crude fat content of the different fish species were significantly different (P<0.05) and C.gariepinus was showed the highest crude fat content (5.74±0.27%). The concentration of K was highest in muscle of C. carpio (17276.21±25.54 mg/kg). The highest concentrations of K, Ca, P, Mg and Mn were found in the C. carpio among the five species. Iron and Zinc value were highest in the C. gariepinus, whereas Copper was highest in muscle of the L. intermedius. The analyzed mineral content found in each fish species was in the order K>Na>Ca>Mg>P>Fe>Zn>Cu>Mn. The present study revealed that all fish species are good sources of proteins and fats, there is need to investigate in detail the types of amino acids and fatty acids of the sampled fishes.
