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.

Happy Anniversary, TVA v. Hill

This week marks the 30th anniversary of one of the most famous environmental law cases in the US--TVA v. Hill. This case was the first time the Endangered Species Act was really tested--could a small fish from eastern Tennessee stop the construction of a $100 million dam? The answer was yes--for a little while.
This case has already been endlessly debated, and we're not likely to change anyone's minds now. Here at TNARI, we're happy that there are still snail darters around to study and conserve. They're a good reminder that we ought to be considering the impacts of our actions on all of biodiversity, not just the commercially important species.

If you'd like to read more about this, this Knoxville News article talks about the case and recent , or for a more legal angle, a Tennessee Bar Association article written by the attorney who argued the case on behalf of the fish.
