Two black bass (Micropterus spp.) caught during the 2026 Bassmaster Classic in Knoxville, TN held on the Tennessee River. The fish on the left is a smallmouth bass, the fish on the right is what is known by bass anglers as a “meanmouth,” which is a hybrid between Alabama bass (M. henshalli) and smallmouth bass (M. dolomieu).

Hatchery vulnerability range for key zebra mussel (Dreissena polumorpha) and quagga mussel (Dreissena rostriformis bugensis) parameters. If your hatchery is within range of all the vulnerability parameters for a given organism, it is at risk for settlement.

Ring Vaccination - Rabies and Vampire Bats

Scientists at the USGS National Wildlife Health Center have been working on vaccines to protect bats from diseases like such as rabies and white-nose syndrome. The most promising method is called orotopical vaccination. By applying the vaccine to the bat’s muzzle, the gel-based vaccine is spread to others in the colony through grooming.
