Domestication Strategies of Tinfoil Barb Barbonymus schwanenfeldii (Bleeker, 1854): Potential Candidate for Freshwater Aquaculture Development

Abstract

This paper discussed domestication strategies of Tinfoil barb from different populations for evaluation of potential fish candidate for freshwater aquaculture development. Collection and maintenance of wild-caught adult fish was the first step in domestication strategies followed by characterization of fish, broodstocks selection and maturation, control of fish reproduction, and larval rearing. The Tinfoil barb presented an excellent performance to adapt to the new environment. This was indicated by survival rate of the fish acclimated in the captive environment of about 69.28 ± 19.64% for five weeks. Phenotypic characterization revealed that Tinfoil barb collected from Borneo, Java, and Sumatra have different morphological characters. Based on genetic characters, polymorphism percentage and heterozygosity of the Borneo tinfoil barb population provided the highest performance followed by Java and Sumatra. The growth model of all Tinfoil barb populations was allometric negative indicating a faster increase in length than in weight. Reproductive performance presented that the fecundity of Tinfoil barb female from Borneo was the highest (2795-5099 eggs/gram) followed by Sumatra (1822-2976 eggs/gram) and Java (2210 eggs/gram). The artificial reproduction performance of broodstock from Borneo also presented more excellent performance than other population after hormonal treatment. Fertility rate and hatching rate were 94,33+0,29 % and 77,44+1,03%, respectively. Java Tinfoil barb had fertility rate 93+0,05% and hatching rate 73,67+3,15%, while it was no fertility rate and hatching rate obtained from Sumatra brood-stock group. Wild-caught adult Tinfoil barb from Borneo population presented the best performance used for potential brood-stock regarding genetic characters, reproductive performances, and response to artificial reproduction. Future studies need to be concerned with the acceleration of gonad maturation and the improvement of larval rearing technology for improvement of domestication strategies of Tinfoil barb as a potential candidate for freshwater aquaculture development.

Analysis of Embryo Development and Early Performance of Larvae of Barbonymus Schwanenfeldii: A Systematic Review

“…In the cleavage phase, the embryo of Torfish species lasts for 10 hours. Furthermore, the process of embryo development in Oryzias woworae species occurs for 1 hour 20 minutes 9 . While the results of observations on the cleavage phase of the embryo in Tawes fish lasted for 2 hours 24 minutes after fertilization (Naskuroh et al 2018).…”

FIRST GENERATION REPRODUCTIVE PERFORMANCE AND SECOND GENERATION LARVAL PRODUCTION ON THE DOMESTICATED TINFOIL BARB, Barbonymus schwanenfeldii (BLEEKER, 1854)

“…In Indonesia, the domestication of TB began with characterizing the genotype, morphological, and biological reproduction of 3 populations, Sumatra, Java, and Kalimantan (Kusmini et al, 2018;Radona et al, 2016a,b), followed by a series of performance evaluations to have the best populations for the domestication program (Radona et al, 2016a,b;Radona et al, 2018;Kusmini et al, 2021). After several generations, investigations of breeding performance showed populations from Kalimantan had the highest growth performance compared to other populations for specific growth rates, survival rates, and feed conversion ratios (Kusmini et al, 2015).…”

“…At a later stage, domestication testing was carried out to evaluate the performance of the Kalimantan population generation obtained to determine the domestication strategy to be carried out (Kurniawan et al, 2021). In the progress of domestication of TB, the promising candidate showed that the mature broodstock was indicated in the weight of 150 to 400 g for females and 200 to 400 g for males (Kusmini et al, 2021), within the size range of the adult wild Barbonymous species (Efizono et al, 2021). The broodstocks reached their gonad maturity level by spawning twice a year.…”
