AUTHORS. James Studdard, Southeast Missouri State University

ABSTRACT. Alligator gar (Atractosteus spatula) are declining throughout their native range. In recent decades, conservation agencies including the Missouri Department of Conservation, have been working on recovering Alligator Gar populations to self-sustaining levels. In many areas of the native range, disconnection of floodplain habitat due to river channelization and flood control have greatly reduced alligator gar habitat diversity and availability. To better manage stocked alligator gar in Missouri, Vemco V16 ultrasonic transmitters are being implanted in hatchery reared juvenile and wild-caught adult alligator gar. The fish implanted with transmitters will be used to track movement and habitat use in four floodplain habitats selected for this study, based on previous stocking abundance. Sidescan sonar was used to collect habitat data and determination of habitat type is based on a 10m X 10m grid. Habitat assessed will be submerged log, log complex (two or more logs), submerged tree limbs, open water, open shoreline, submerged vegetation, standing trees, and tree roots. Depth, temperature, pH, dissolved oxygen, and conductivity is also being factored into the habitat selection. The information gathered in this study is important to determine seasonal habitat selection and help form potential future management actions, including habitat restoration efforts and identification of additional reintroduction sites within Missouri.
