Multiple origins define the genetic structure of tiger shrimp Penaeus monodon in the colombian Caribbean Sea

The tiger shrimp Penaeus monodon is a native species of the Indo-Pacific Ocean that was introduced to promote its cultivation in several American countries, including Colombia. As result inappropriate aquaculture practices, it has established itself wild almost all Colombian Caribbean Sea. To evaluate genetic diversity, population structure, and origin founder populations, samples from three sites were analyzed 10 microsatellite loci mitochondrial DNA Control Region. Genetic diversity similar populations found be present relatively discrete populmoations their related natural Thailand, Philippines, Taiwan China.
