Outbreeding Performance of Tinfoil Barb Barbonymus schwanenfeldii from Java and Kalimantan for Aquaculture Development

Abstract

Aquaculture development of tinfoil barb farming is needed to increase production. This study aimed to evaluate the reproductive performance, growth and heterosis value on outbreeding of two tinfoil barb populations (Java and Kalimantan) reciprocally. Spawning was conducted by induced breeding using hormone stimulation (at dose of HCG 500 IU/Kg and dose of LHRH analog 0.6 mL/Kg). Spawning was carried in the aquarium with 1 x 0.5 m length and 50 cm height of fresh water as full sib ratio 1:1 (one female: one male). The measurement of hybrid in each population was repeated three times. The data were analyzed using analysis of variance (ANOVA), followed by Duncan test. Result showed that fingerlings resulted from ♀ Kalimantan and ♂ Java exhibited the highest reproductive and growth performances (P<0.05) with fertilization rate (94.17%), absolute length gain (2.85 cm), absolute weight gain (0.33 g), specific growth rate of length and weight (2.35% and 4.02%), and survival rate (57.20%).
