The chemical compositions gross energy and mineral contents were determined for sun dried fish: Lates
niloticus, Tetraodon lineatus, Heterotis niloticus, Mormyrus niloticus, Clarias lazera and Protopterus
annectens. Protein value of over 70g/100g was recorded for the analyzed fish except C. lazera which
contained (59.9±1.4g/100g). The range of lipid content was (2±0.1-16.6±0.8g/100g), with the highest
values in C. lazera and M. niloticus. The range of ash was (3.9±0.1-13.6±0.9g/100g), high in
P. annectens and C. lazera than in remaining species. Energy value was (475-555 Kcal/100g) high in
C. lazera. Minerals were dominated by Ca, Na, K and P which form 99% of total minerals. The value of
Mg was (1.4-2mg/100g) and the values of other minerals were <1mg/100g. The results revealed that
sun-dried product (Kajaike) of Nile fish is a good source of proteins, minerals as well as energy, thus
has high nutritional value for healthy diet. The data may benefit the fishery industry, nutritionists and
researchers to improve the nutritive value, processing techniques and marketing of selected fish. |
