Regional tinfoil barb imports can alter its native species genetic makeup. Journal of Sustainability Science and Management, 14 (6). ISSN 2672-7226 (2019)
Abstract
Tinfoil barb, Barbonymus schwanfeldii is part of Malaysian inland fish commodity and being trade as ornamental fish, alternative protein and aquaculture industries. It is now within transboundary demand-supply chains of Indonesia, Singapore, Malaysia and Thailand. An inquest on gene hybridization from the trade used morphometric, meristic and phylogenetic tree construction. Mitochondrial cytochrome c oxidase 1 gene codes of three fish, each acquired from five different ornamental traders are revealed some degree of native gene dilution. As such, bootstrap values above 90 were produced after comparison with Indonesian fish, whereas it was below 90 when compared to Malaysian fish. This
finding suggests that Malaysian B. schwanfeldii may have cross-bred with same species of non-native origin when held in captivity and it diluted the filial genetic make-up. Dilution
of native genetic information cause gene hybridization and this adaptable individuals (an alternative perspective of natural selection) could become invasive. In-line with invasive
alien species management, Convention on Biological Diversity has asserted the need for good practices that abide to Transnational Policy Network on Invasive Alien Species. It
is suggested that alike-species transboundary exports should forgo ornamental intentions and focus instead on the sustainable alternative protein supply to compensate regional
transboundary food security.
