Abstract
A research to explore morpho-anatomcal changes and energy storage on various organs during gonadal development of twospots catfish, Mystus nigriceps was carried out in Klawing River, Purbalingga, Central Java. Morpho-anatomical parameter  e.g.  condition  factor, viscera  somatic  index, adipose  fin  index,  hepato  somatic  index, gonado  somatic  index; and energy content of muscle of dorsal region, visceral organ, adipose fin, liver, and gonad tissue were measured based on gonad development stages. The results showed that morpho-anatomy and energy content in tissues have changed during the period of gonadal development. Moreover, there were a process of storage, transfer and transformation of energetic substances for gonad maturation and spawning activities.

Keywords: energetic substances, morpho-anatomical changes, energy storage, gonadal development.
