In conclusion, fresh fish consumption is recommended for children because of less percentage of crude fiber which is responsible for its faster digestibility compared to that of dry fish. This work supports the work of Eyo (2001) who reported that fish has a great digestibility. Dried fish also contain higher percentage of fats which is responsible for the supplies of omega-3 PUFAS for lowering blood cholesterol level and high blood pressure. In general, there were great influences of drying on proximate compositions of both C. gariepinus and O. niloticus. These result showed that different nutritional components of fish undergo different changes at elevated temperatures.
