Here we used both microsatellites and mtCR (mitochondrial DNA control region) sequences as genetic markers to examine the genetic diversity and population structure of Penaeus monodon shrimp from six Indonesian regions. The microsatellite data showed that shrimp from the Indian and the Pacific Ocean were genetically distinct from each other. It has been reported previously that P. monodon mt CR sequences from the Indo‐Pacific group into two major paralogous clades of unclear origin. Here we show that the population structure inferred from mt CR sequences matches the microsatellite‐based population structure for one of these clades. This is consistent with the notion that this mt CR clade shares evolutionary history with nuclear DNA and may thus represent nuclear mitochondrial pseudogenes (Numts).
