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%).

Highlights

Tinfoil barb is known as a native species in Indonesia with good economic value (IDR 25,000-40,000/kg) [1]
This study aimed to evaluate reproductive performance, growth, and heterosis values of the outbreeding results of two tinfoil barb populations (Java and Kalimantan) for aquaculture development
Fish used in this study were two populations originating from Java (Center for Conservation of General Aquatic Fisheries, Department of Marine and Fisheries, West Java Province) with environmental characteristics of temperature: 24-30oC, pH: 5-7 and dissolved oxygen: 4-5.6 ppm and from Kalimantan (Central for Fish Culture, Anjungan, West Kalimantan) with environmental characteristics of temperature: 29-33oC, pH: 5-7.4 and dissolved oxygen: 4.56.6 ppm

Summary

Introduction

Tinfoil barb is known as a native species in Indonesia with good economic value (IDR 25,000-40,000/kg) [1]. This species is popular for consumption due to its taste. Tinfoil barb culture in Indonesia has been carried out since 2010. In aquaculture activities, the adaptability of tinfoil barb in aquaculture environments is relatively low with the survival value of 69.28 ± 19.64% and growth of 1-2 cm at the age of 50-60 days [2]. The low adaptability of this species on aquaculture environment is probably due to availability of brood fish which would increase the inbreeding. Inbreeding causes in lowering the genetic diversity which would decrease adaptability and productivity [3]
