Název v původním jazyce

A Quantitative Study of Germ Cell Populations as Releated to 17?-methyltestosterone induction of Sex inversion of Common carp (Cyprinus carpio L.)

Popis výsledku v původním jazyce

The main objective of the present study was to investigate the effects of 17 ? -methyltestosterone treatment upon the testicular germ cells of gynogenetic masculinized neomale common carp (Cyprinus carpio L.) in comparison with diploid carp. Gynogeneticcommon carp progeny (mean body weight, BW, 2.6?0.3 g; mean total length, 10.4?0.5 cm) were treated for a period of 40 days with 17a-methyltestosterone (MT) at a dose of 100 mg kg1. The oral administration of MT resulted in 61.5 - 100% of fish exhibitingmale gonads. The masculinized neomales exhibited reduced (P < 0.05) body weight (BW 22.9?0.8) but significantly increased (P < 0.05) mean testis weight (2.1?0.3) and mean gonadosomatic index (GSI 9.5?0.2%) in comparison with fish not treated with MT (BW54.8?1.3; GSI 0.61%). Furthermore, treatment with MT also resulted in an increased number of fish exhibiting abnormal gonads. However, neomales did not exhibit abnormalities in the development of sperm ducts. MT treatment significantly in
