Students from the Chattanooga Girls Leadership Academy and GPS are taking a hands-on approach to Wednesday's science lesson.

They will join a group of scientists from the Tennessee Aquarium Conservation Institute and TWRA in Coolidge Park to release 89 Lake Sturgeon into the Tennessee River.  The release will be at 4:00 p.m. 

These juvenile fish measure about 15 inches long, more than double the size of the ones typically released by the Aquarium and its conservation partners. They were held for longer at the Aquarium to better understand any potential effects of using tracking tags to monitor their movement after release.

These fish, which are listed as endangered in Tennessee and 18 other states, once thrived in these waterways but all but disappeared in the 1970s due to overfishing, low water quality and man-made alterations to the waterway.

Lake Sturgeon are listed as "Endangered" in Tennessee and may not be harvested, but anglers play a key role in monitoring Lake Sturgeon populations. To report a Lake Sturgeon catch, go to http://icaughtone.org/
