\textbf{Abstract}
\begin{abstract}
\normalsize{
Fish is an important global food commodity because it provides the needed animal protein required in human and animal diets. However, fish is highly susceptible to deterioration and it has been observed that inappropriate preservation and storage techniques are major causes of a substantial shortfall in fish availability, nutritional quality and the economies of many fisher folks, especially in the tropics. This study was carried out to evaluate the effectiveness of processing technique and storage material on the nutritional stability of two commercially important tropical freshwater fish, \textit{Clarias gariepinus} and \textit{Tilapia zillii} during an eight week storage period. Live samples of earthen pond cultured fish and another batch from a naturally occurring lake were obtained and transported to the laboratory of the Department of Animal and Environmental Biology, Adekunle Ajasin University, Akungba-Akoko, Nigeria where they were sacrificed and the proximate composition of a batch was determined immediately. Using standard procedures, two other batches of the fish samples were separately oven"=dried/kiln"=dried, stored in aluminum foil, paper carton, plastic container, polythene bag and raffia woven basket, and left on the shelf for 8 weeks prior to proximate determination. The data obtained in the study showed that the samples subjected to kiln smoking and electric oven drying were significantly different ($p < 0.05$) in their proximate compositions when compared to the fresh fish samples irrespective of the storage material. However, the results indicated that airtight plastic proved to be the best storage material for both \textit{C. gariepinus} and \textit{T. zillii} because it provided the relative nutritional stability during the storage period. It is recommended that smoked and oven- dried fish should be stored in air- tight plastic containers. It is expected that the results obtained in the study would elicit adequate information on the appropriate processing and storage techniques of fish products.}
