| Özet |
| Seconder sex characteristics are phenotypic specifications in living organisms morphologicallydistinguishable and available for sex discrimination. Breeding tubercles that white nodules because of epidermiccells differentiation head, dorsal and caudal sections and fins are one of these properties. Breeding tubercles haveconsidered to consist of some reasons such as communicating with females or stimulating reproduction, andterritoriality throughout the breeding period. Especially tubercles occur in male fishes at breeding period aretriggered off pituitary and sex hormones and then disappeared. These tubercles are formed in lots of fish speciesin breeding period were reported and these fishes have got tubercles consist of 4 orders and 15 families:Salmoniformes, Gonorynchiformes, Cypriniformes ve Perciformes. Breeding tubercles are also observed inmales of Cyprinus carpio live in the Van Lake Basin and males of Alburnus tarichi ve Capoeta kosswigi areendemic for the Van Lake Basin in breeding session. Breeding tubercles firstly are formed on head of the fishesin middle of May afterwards on dorsal and caudal sections with ventral, pectoral and anal fins in June. However,small amount of tubercles were observed in August. At the different water resources in the Van Lake Basin,there are some differences in the way of forming times according to water temparature for the same species. Inthis study, structures, shapes, occuring on fish sections of tubercles and fish species with tubercles were focused. |
