Effect of Poor Handling on the Nutritional Composition of Some Imported Frozen Fishes in Nigeria
Abstract
This study aimed to determine and compare proximate composition of three commonly commercial imported frozen fish species in Nigeria (Scromber scrombrus, Trachurus trachurus and Sardinella aurita) with reference to poor handling and size. Major nutrient compositions of raw muscles like protein, fat, moisture, ash were estimated. Fish samples were collected from importing fishing company in Lagos State (loading point) (location I) and three cold rooms in Ogun State (location II). Proximate analysis revealed that the protein, carbohydrate, lipid ash and fibre contents were high in the three species in the two locations even though nutrition quality of the three frozen fish samples obtained in the location I were higher than location II. The results revealed that the correlations between weights and proximate composition were relatively precise for moisture and protein, but were much more variable for lipid content, ash and crude fibre.
