Silver Barb  (Leptobarbus hoevenii Bleeker, 1851) is one of the Indonesian indigenous fish species that are native to freshwater habitats for public consumption and depleting natural population in Sumatera inland waters. The local name of this fish in Jambi, South Sumatra and Lampung, namely lemak/klemak, manjuhan in Central Kalimantan, sultan in Malaysia and Pla Ba in Thailand. But when a small sized between 10-20 cm is called jelejar in Jambi, South Sumatra and Lampung. Since 2006, Jambi Freshwater Aquaculture Development Center (JFADC) have succeeded in producing jelawat fish seed artificially induced breeding method for the first time in Sumatera.

The first generation Hoven's Carp broodstock (G1), Gonado Somatic Index (GSI) was obtained from the broodstock surgical female fish that died during the induced breeding process.  Gonad weight of female broodstock ranges between 10-12%. Egg Somatic Index (ESI) is the number of eggs released compared to the weight of broodstock. The data of ESI were made by artificial spawning.  ESI ranged from 7.6% to 11.80%. Fertilization Rate (FR) ranged between 70-95%, and 80-90% sperm motility. While the range of Hatching Rate (HR) is 15-95%.  Handling at the time of selection, injection and stripping done slowly to reduce stress levels.  At hatching eggs process are given a large aerated so that the need for dissolved oxygen in embryonic development can be met and also setting the temperature ranges from 27 - 300C.

The amount of 1 gram ovulated eggs ranges between 550-600 eggs. While, the amount of 1 mL fertilized eggs are 70 eggs per 1 mL. Latency time varies between 4-20 hours at the temperature range of 26-300 C.
