Abstract: Gonadosomatic Index (GSI), Hepatosomatic Index (HSI) and proportion of oocytes stadia related with reproduction activity and already used by researcher as an indicator of spawning season. The present study, we evaluated ovary maturation estimation that indicates spawning season based on GSI, HSI and proportion of oocytes stadia. A total of 93 females rainbowfish M. boesemani was caught using handnet in Seta, Tiwit and Sagsiger, Maybrat Regency, West Papua. Fish samples body weight was measured then dissected to determined ovary maturation stages temporally. The highest GSI, HSI and proportion of mature oocytes analysis temporally was found in August i.e 2.163%, 2.276%, and 22.66% respectively. Based on temporally analysis from June to Nopember 2013 of GSI, HSI and proportion of oocytes stadia, we assumed that M. boesemani populations have experienced a series multiple spawning a year with peak of spawning season in August.
