November 14, 2025 –Aboard this 65-foot vessel, nothing much happens most of the time. The VHF marine radio crackles with mundane chatter. The Atlantic Ocean ebbs and swells. Below deck, crew members resort to playing Uno.
Then, everything happens all at once.
After four hours of “soaking” in ocean currents, the baited fishhooks are ready to be reeled in. A huge winch squeals to life, winding in the mile-long fishing line. Just below the surface of the water, a ghostly silhouette flickers into view.
It has arrived — the day’s first shark.
“Up!” several voices call in unison, an instruction to raise the hammock-like gurney six or seven feet to the boat’s railing. The sandbar shark nearly thrashes free, but two gloved hands show up just in time to gently, but firmly, coax the giant fish to stay put.
“That was a very alive one,” said Samuel Ruth, a few minutes after returning the shark into the waters where the ocean mingles with the Chesapeake Bay.
his is catch-and-release with a higher purpose. During the minute or two that the shark is out of the water, Ruth and his colleagues race to record vital information — its sex, length and weight (if it’s small enough to fit on the scale). The whirlwind of activity also includes collecting a DNA sample, affixing an ID tag below its dorsal fin and snapping photos to aid in future identification.
For more than five decades, the Virginia Institute of Marine Science’s shark research group has worked to pull back the veil on these mysterious creatures. Their research has helped protect sharks from overfishing, documented how they respond to climate change and shed light on their not infrequent appearances in the Chesapeake Bay.
The work is crucial for understanding sharks themselves as well as the marine ecosystems they inhabit, said Jameson Gregg, a senior marine scientist at VIMS.
