With an aim tp reveal the actual quality of dried freshwater fish on the Ghanaian market, chemical, bacteriological and organoleptic examinations were carried out on 42 unsalted-grilled and 73 saslted dried tilapia. Retail prices per kg of the products were also recroded. There was no significant difference between the average retail prices of the two products. For both dried fish, there existed negative and significant correlation (P<0.001) between fish weight and the retail prices. No significant correlation was found between the retail prices and organoleptic scores. Average water content of unsalted-grilled fish was 58% and that of salted-dried ones, 45% with 16% salt. Average appearance and odor scores of both products fell between fair and good. For grilledfish, taste panel scores significantly correlated with appearance and odor scores (P<0.05), and log (total viable counts) (P<0.02). But salted tilapia demonstrated no significant correlation of the taste panel scores teh these two variables. The data suggest that in drafting the quality standards of these two products, different criteria should be adopted.
