Seasonal variation in the chemical composition of Cystoseira barbata (Stackhouse) C. Agardh distributed in the Strait of Çanakkale

Studies on the chemistry of algae began in 1900s and today continue to increase. In these studies algae have been investigated as a food source and were found to contain significant amounts of nutrients (Lee et al, 1977; John et al, 1980). In this study, the seasonal changes in the chemical composition of Cystoseira barbata (Stackhouse) C. Agardh taxa taken from four different locations of the Dardanelles (Turkey) were examined. In the samples, depending on the season and the sampling location, different results for nutrients in raw materials were indicated. At the end of this study, results were obtained for the annual distribution of C. barbata for different seasons and different locations. According to the results, the highest protein amount (17,42 plus or minus 0,92 %) in C. barbata was obtained in spring, the minimum protein amount (6,77 plus or minus 0,42 %) was also obtained in spring but for different location. The highest lipid amount was determined in Havuzlar (5,05 plus or minus 0,23 %) in winter, the minimum lipid amount (0,79 plus or minus 0,54 %) was determined in Havuzlar in spring. The minimum ash amount (15,43 plus or minus 0,77 %) was obtained in Gelibolu in summer and the highest amount of ash (38,3 plus or minus 0,52 %) was determined in Havuzlar in autumn.
