Genetically determined population structure among hogfish ( Lachnolaimus maximus) (number of 
specimens=719) in the southeastern United States, according to posterior probability assignment 
produced by the analysis of 24 polymorphic microsatellite loci (4.5x10® burn-in, and 9.0x10® replica- 
tions) with the program STRUCTURE. The output from 10 replicates from the program CLUMPP 
for 719 specimens and 9 sampling areas indicates (A) cluster percentage per individual for the high- 
est modal value (number of genetic clusters) when K= 2 (specimens were collected from the following 
sampling areas: 1-324 from sampling areas 1-5; 325-394 from sampling area 6; 395-616 from sam- 
pling areas 7 and 8; and 617-719 from sampling area 9); (B) cluster percentage for each individual, 
grouped by sampling areas for the best modal value of K= 3 (hogfish population structure) by using 
the program DISTRUCT; and (C) proportional values represented by each cluster within sampling 
areas 1-9. Hogfish specimens were collected from November 2005 through August 2013 from north- 
west Florida to the Carolinas.
