Florida

Illinois

  • Alligator Gar have been reintroduced into power plant lakes and off-channel habitat of the Illinois river in the northern part of the state.

Kentucky

  • Murray State University investigated diet composition within Clarks River, investigating morphological differences in species of gar to educate public on Alligator Gar awareness, Partnered with Kentucky Department of Fish & Wildlife for reintroduction efforts in Clarks River.

Louisiana

  • USFWS Baton Rouge and the GCPO LCC used GIS models and telemetry data to create a Spawning Habitat Suitability Index which helps locate potential spawning areas of alligator gar. Visual observation by USFWS biologists of Alligator Gar spawning within predicted area lends utility to this model.
  • LSU masters student in collaboration with USFWS and GCPOLCC, investigated fish-habitat relationships and identified aquatic habitat conditions that promote healthy alligator gar populations. Objectives for this study were to: 1) identify floodplain habitat features associated with desired fish assemblage characteristics based on the role of Alligator Gar as a surrogate species; and 2) develop a sampling protocol for surveying alligator gar with side-scan sonar.
