The composition of fatty acids (FA) in sturgeon, was studied during cold storage at 4 degreesC. Three different categories of lipid tissues (intramuscular, subcutaneous and intraperitoneal), were sampled at 0, 3 and 5 days of cold storage. The results showed a good level of preservation of the polyunsaturated fatty acid (PUFA) during the first 3 days of storage. Significant differences (p:5:0,05) were found between means at 0 and 5 days: at the day 0 PUFA in intramuscular, in subcutaneous and in intraperitoneal lipid tissues were respectively 18.86, 21.52 and 17.23 g/100 g of lipid extract, while at day 5 after death there were 12.34, 11.86 and 10.01 g/100 g of lipid extract, respectively. Results showed a strong decrease of FA content of the three lipid tissues sampled during the five days of cold storage and the main FA classes showed a similar trend of variation.
