This week, we picked up 48 Barrens Topminnows (Fundulus julisia) from Matt at the Tennessee Aquarium. The Barrens Topminnow, (or BTMs), are one of the most imperiled fishes in the southeastern U.S. They are restricted to three counties in central Tennessee, and much of their habitat has been affected by human encroachment and ongoing drought. Worst of all has been the introduced Western Mosquitofish (Gambusia affinis), which outcompete BTMs. Drought conditions have been so severe at times that biologists have had to "rescue" populations from shrinking bodies of water that are nearly dry. The fish we received at TNARI are from one such population. TNARI will provide additional husbandry space for BTM propagation to help restore this beautiful southeastern fish.
