Abstract
Of the nearly 600 crayfish species worldwide, more than half are native to North America. The southeastern USA is the epicenter of global crayfish species richness. There is concern about the conservation status of many crayfish species and the viability of their populations. Procambarus acutissimus is a surface dwelling crayfish that is native in Mississippi and Alabama and has isolated populations in west Georgia. Its limited distribution in Georgia prompted this re-assessment of a previously surveyed population in a wetland complex near Columbus, Georgia. To assess the population status of P. acutissimus, we used baited Gee minnow traps to survey crayfish in 2014 following similar protocols used in a 1994 survey. Catches from the littoral zone of a borrow pit lake shifted from only P. acutissimus in 1994 to only Procambarus clarkii, a non-indigenous, invasive species in 2014. Trapping in 2014 documented P. acutissimus in only one of five isolated wetland depressions sampled. Procambarus clarkii appears to be replacing P. acutissimus in this wetland complex. Our results suggest that P. clarkii may displace other crayfish, particularly those that share its affinity for wetland habitats.
