Alex Haro holds a juvenile sea lamprey (transformer) prior to tagging for a light deterrent study at EESC S.O. Conte Research laboratory's fish passage complex.  This lamprey has begun its dramatic metamorphosis developing eyes and oral disks covered with pointy teeth and is ready to begin migrating downstream to the sea.

Alex Haro prepares to implant passive integrated transponder (PIT) tag into juvenile lamprey (transformer) in preparation for a light deterrent study at EESC S.O. Conte Research laboratory's fish passage complex.

A dermal swab being used on a Largemouth Bass at a Bass Pro Shops retail store with a presumptive case of blotchy bass syndrome.   We can see the transfer of pigmented epidermal tissue to the swab changing its color. The collected swabs can be used to isolate DNA and RNA which can be used to identify pathogens including those associated with hyperpigmentation.

Vicki Blazer's group sampling smallmouth bass to do PFAS analysis of blood and blood plasma along with collecting tissues to look at other indicators of fish health such as histopathology and gene expression. These photos were taken at a sampling site in PA during October 2021. 

The buffy “teardrops” you see on some of the feathers indicate that this Swainson's Thrush hatched this summer and is making its first-ever migratory journey! This bird that was banded October 1, 2021 at the Bird Banding Lab’s fall migration banding station at Patuxent Research Refuge in Maryland.
