In recent years there have been numerous research with the aim of generating new resources from different raw materials such as alternative crops. Algae and cellulosic residues. Marine resources has become more important for the last few decades because terrestial and industrial resources cannot supply with the requirement of human population. Also aquatic species have a potential usage to be an alternative renewable crop for the production of several fields from fertilizers to industrial products. The most important member of the aquatic ecosystem is the Algae Marine algae have emerged as an alternative feedstock for the production of numbers of renewable feedstocks. In addition to energy potential, they are the base of chain – photosynthetic organisms including their capability to absorb carbon dioxide higher productivity rates. In the present study seasonal and regional variances of protein, lipid and ash amount of some brown algae (Ochrophyta) along the coast of Çanakkale (Dardanelles) were investigated. The chemical analyses (lipid, ash, protein analyses and the amount of nitrogen free extract) were carried out seasonally. In results significant differences were recorded for the species collected in different seasons and six stations.
