Capoeta trutta (Heckel, 1843)'da Bazı İskelet Yapılarının Gelişimi.

In this study, the development of some bony structures of Capoeta trutta (Heckel, 1843) from Keban Dam Lake was investigated. For this purpose, 50 fish samples were examined from January-2013 to December-2014. Fishes were brought to the anatomy laboratory in Faculty of Fisheries Fırat University. Dorsal fin rays were counted after their lengths and weights have been determined. The internal organs were removed, then they were boiled in a pot of hot water for 1-5 minutes and all bony structures were separated from the meat. Bony structures were cleaned, dried and weighed. The lengths and weights of some selected bony structures were also determined. Fish age was determined from first rays of dorsal fin. The changes of total bony weight, the weights and lengths of some bony structures were determined with the changes of age, weight and length of fish. Fish samples were 4-9 in age, 22.5-40.23 cm in standard length and 243.75-1060.10 g in weight. The number of dorsal fin rays were counted as 11 (3 hard + 8 soft rays). The number, mean weight and mean diameter of the vertebrae were 39-43, 2.35-10.72 g and 3.43-6.54 mm respectively. Mean weight of all bony structures was 8.75-42.73 g and the percentage of bony weight was 3.49-4.47%. The highest value was determined in age group 7 fishes. In general, it was seen that there was a compatibility between skeletal growth and general development of C. trutta. [ABSTRACT FROM AUTHOR]
