DNA barcoding and genetic variation in caged pangasiids in Pahang River Basin

The domestication aquaculture selection in farm environment can cause changes in phenotype and genotype of farmed fishes, which may later influence the demographic structure of wild populations if they accidentally escaped from cages. This is an alarming situation for conservation of native specie...
