Genetic diversity and albumin content of striped snakehead Channa striata in Indonesia; a study on farmed and wild fish from five main islands

Abstract Genetic characterization and eminent traits of species are crucial in determining the direction of aquaculture development. The genetic diversity of striped snakehead ( Channa striata ) across five main islands in Indonesia from aquaculture and wild was explored through its partial mtDNA COI. Subsequently, this study examined the albumin content extracted from the meat and comprehensively aligned it with the variation of its genotype. Phylogeny studies showed the Sumatran snakehead fish sample forms its own cluster and has a long genetic distance from other samples. Interestingly, its albumin content in Sumatra samples was significantly higher (1.907%) than others (1.253-1.509%). Further analysis of albumin content from the Borneo samples from the same taxa in the phylogeny tree, showed no significant difference between farmed and wild C. striata . The findings of this study are fundamental for initiating a selective breeding program and developing conservation management.
