The Nutritive Value of Nylotic Fish
Journal Title: Biomedical Journal of Scientific & Technical Research (BJSTR) - Year 2017, Vol 1, Issue 4
Abstract
Fishing is one of the oldest occupations in Sudan. Fishing has assumed much importance in view of the rapidly growing population and depleting land resources. Fish confirm a very nutritional part of man’s diet. It is rich in protein. It contains a good selection of minerals and vitamins. This study was conducted in estimating these biochemical components. 300 samples of Nylotic fish were tested. It was found that the levels of sodium is 72-85mg/100 g, potassium 279-380, calcium 79-210, magnesium 38-95, iron 1.55-3.4, zinc 0.96-1.34, copper 0.20-1.4. The vitamins tested were found to be 70-350(I.U) for vitamin A and 1.5-3.6 μg/g for vitamin C. The protein was found to be 15-20% whereas the fat 20-30%.Sudan’s huge fishing potentialities and fish resources are represented by the 800 kilometers coastline on the Red Sea and about 42 billion square meters of fresh water stretched from lakes and rivers, the most important of which are the river Nile and its tributaries. That collectively harbors an estimated fish potential of 23700 tons annually and produces 17000 tons annually. The fish inventory reservoirs at Sennar, Roseiris, and Jebel Awlia Dam in addition to the Nubian lake at Wadi Halfa, account for hundreds of thousand tons of fish in fresh and marine waters FAO [1].The inland fisheries are mainly on the River Nile and its tributaries, contributing over 90% of the estimated production potential of the country. The sudd swamps in the south and the manmade lakes on the White Nile (Gebel Awlia Reservoir), the Blue Nile Reservoir Sennar Reservoir and Atbara River (Khashm Elgirba Reservoir) are the major fishing localities with respect to fish resource magnitude and exploitation thrust. People in the developing countries are generally much more dependent on fish as a part of their daily diets than people living in the developed world. It may be used fresh, frozen, canned, cured salted, dried or smoked. Fish meal and fish flour are two products of the fishing industry used for the dairy animals and poultry feeds and so add to the world’s supply of protein rich food.
