Abstract: To assess the fish by-products released, we surveyed 158 fish pre-caterers and 33 structures in 12 markets in Douala. A random sample of these by-products was used for bromatological analysis. Oils extracted from these samples were characterized by determining some chemical indexes. Investigation showed more than 238 tons of by-products are annually released into the environment of the observed markets. Flour Analysis of by-products showed a moisture content of 22.04 ± 0.03%, 50.29 ± 0.02% proteins, 29.03 ± 0.15% ash, 20.3 ± 0.03% lipids, 0.37 ± 0.15% total carbohydrates, and mineral elements such as calcium (6.08 ± 0.002 g / kg), phosphorus (7.093 ± 0.003 g / kg), and iron (328 ± 2.65 mg / kg). Analyses of chemical indexes of the oil extracted showed that they were within the range of Codex Alimentarius standard values. It can be concluded that Douala market’s fish by-products are of good nutritional quality and could therefore be used in animal nutrition.
