The goal of present study was to examine African catfish (Clarias gariepinus
, 1822) maturation (gonadogenesis and oogenesis) under outdoor conditions of Uzbekistan in 2016. Gonad stages of maturity were characterized using common 5 stage scale. Oogenesis was divided into 5 stages, which followed one after the other. Artificial reproduction, eggs hatching and fry rising were carried out in February (2016) in indoor facilities. In the middle April fry (19.4 g) were stored in outdoor tanks. African catfish matured at the age of 8 months. Fish matured when the body weight was 185 – 200 g, total length was 28-30 cm for females and 180-185 g and 26-26.5 cm for males, relatively. The diameter of ripe oocytes was 1.0-1.2 mm.Pages: 236-239 | 599 Views 26 DownloadsDownload Full Article:
