Total protein content (%) of  </span> <span style="font-family:’Times New Roman’, serif;">C. antalyensis varied from 63.80% to 78.15% and total fat content from 4.57% to 21.29% in different seasons.  </span> <span style="font-family:’Times New Roman’, serif;">The palmitic, stearic, palmitoleic, oleic, eicosapentaenoic and docosahexaenoic acids were the most abundant  </span> <span style="font-family:’Times New Roman’, serif;">fatty acids in the muscles of C. antalyensis. The ratio of eicosapentaenoic acid (EPA) in muscles of both genders  </span> <span style="font-family:’Times New Roman’, serif;">was higher in spring and autumn, while docosahexaenoic acid (DHA) ratio was higher in winter. The ratio of  </span> <span style="font-family:’Times New Roman’, serif;">omega 3 polyunsaturated fatty acids (n3 PUFAs) content in the muscles reached the highest level in spring in  </span> <span style="font-family:’Times New Roman’, serif;">males and in summer in females. The ratios of n-3 PUFAs to omega 6 polyunsaturated fatty acids (n6 PUFAs)  </span> <span style="font-family:’Times New Roman’, serif;">in muscles of C. antalyensis of both genders changed from 3.29 to 5.44 as the seasons changed. Total fat and  </span> <span style="font-family:’Times New Roman’, serif;">fatty acid contents were found to be at the lowest level in both genders during winter. This shows that nutritional  </span> <span style="font-family:’Times New Roman’, serif;">content of C. antalyensis species is quite affected by variation in seasonal conditions. </span> </div>}, number={1}, publisher={Istanbul University}
