Little is known about the genetic structure of grass shrimp, Palaemonetes pugio, populations or the effects the parasite Microphallus turgidus has on it. The objective of this study was to determine the amount of genetic diversity of the shrimp populations based on locality and parasite load. In order to examine the genetics of P. pugio, shrimp DNA was extracted and scanned using single stand conformation polymorphism. Results revealed P. pugio populations are highly conserved among localities. This suggests a significant amount of gene flow is taking place. Results also indicate there is no correlation between the most common host haplotype and parasite density, as shown in previous studies on host-parasite interactions. Further studies in this field will provide clearer answers in understanding the genetics of P. pugio.
