Abstract
Asian arowana (Scleropages formosus) is listed by CITES as a highly endangered fish species. The genetic diversity and population structure of three Asian arowana captive stocks was analyzed using microsatellites and AFLP markers on 32 randomly collected individuals from each stock. Six AFLP primer pairs amplified a total of 324 bands across the three sample sets. The green stock showed the highest percentage of polymorphic bands (15.6%) and expected heterozygosity (0.26), followed by the red (13.0% and 0.24), then the golden one (12.7% and 0.22). Microsatellite analysis showed high allelic and gene diversity in all three varieties. The green stock showed higher allele number (100) and higher gene diversity (0.75) than the red (98 and 0.74) and golden ones (85 and 0.71), respectively. The estimates of long-term effective population size by two different methods ranged from 4741 to 7288 and from 25,056 to 64,641, respectively. Tests of heterozygosity and allele frequency distribution indicate that a recent bottleneck in any of the three captive populations is highly unlikely. Altogether, the data suggest that the captive breeding program for conservation and sustainable use of the endangered Asian arowana will be successful. In addition, we found that the differentiation among populations was intermediate (FST=0.047, RST=0.103) and the genetic distance was the smallest between the green and red, whereas the largest between the red and golden varieties.
