Effet Des Saisons De Pêche Sur La Qualité Nutritionnelle De La Sardine « Sardina Pilchardus » Péchée Dans La Zone De Mostaganem

Résumé: The wilaya of Mostaganem represent a major fishing area in Algeria .This specificity has given for the wilaya a great importance in the national fisheries sector development strategy and fishery resources, especially for the species of sardines (Sardina pilchardus). The purpose of our work is to study and evaluate the nutritional quality of the most common species in the coast of western Algeria during the month of January and May ; Sardina pilchardus, with a sizeable stock of fisheries resources. The results of biochemical analyzes confirmed a sample of the fat content of 2013 (11,4g/100g) greater than 2016 (9,11g/100g)those that probably explains the decrease of plancton in the marine environment may have been linked to marine pollution therefore a loss in wealth of fish in polyunsaturated fatty acid that enters the prevention of cardiovasculardisease, in the quotient intelligence of children and in the prevention of several diseases .on the other hand the protein content is important in the sardine flesh of 2013 in May (20,44%) , during the same period the average of the sardine protein analyzed this year 2016 isexpressed (18.10%). The index of TBA is a good indicator of fish rancidity , the results show a value of TBA not exceeding the threshold with a value of (MDA equivalent 0,49mg / kg vs 0.52 mg equivalent MDA / kg) in both years (2013.2016) in May respectively which confirms the freshness of the samples.
