Detection probabilities for these fishes are typically low, especially using conventional capture-survey method due to the fish’s behaviour of hiding beneath the water’s surface. Hence, the environmental DNA (eDNA) monitoring is a relatively new approach that can be used to assess the distribution of these invasive fishes. Here, we report the strategy to develop small fragment (280- 400 bp) specific-specific primers for three selected invasive Cichla species namely, C. ocellaris, C. monoculus, and C. kelberi based on mitochondrial DNA (mtDNA) sequences. Current research showed that the developed species-specific primers from cytochrome oxidase I (COI) gene has high resolution at species level. Species-specific amplification tests also proved the specificity of the developed primers, securing the high- level species identification potential which may help in control...
