Abstract: Monopterus cuchia (Hamilton) is one of the most expensive species due to its high nutritional and medicinal values. Analysis of gonadal maturation of M. cuchia was done to understand the reproductive biology as well as to identify its peak maturity for breeding. Monthly variation of Gonado-Somatic Index (GSI) reflects the gonadal maturing progression. Different stages of oogenetic development were examined microscopically. Based on the histological characteristics of testis and ovary, four stages of development were described. Scanning electron microscope (SEM) study was used to analyze and further supplement the findings by histology. This paper provides new information on histological analysis and ultra structures of maturation of gametes showing different developmental stages of both male and female species of M. cuchia in Meghalaya, India. Therefore observation of gonads was done to ascertain the actual pattern of maturation of gonads and eventually helps in determining period for actual induced breeding of the species which breeds once in a year.
