Sharks & Other Fish


New technology expected to play a key role in shark research

Cape Cod Times

In November, Skomal and the Atlantic White Shark Conservancy fitted two sharks with new satellite positioning tags developed by a team at Woods Hole Oceanographic Institution that can be fastened to a white shark’s fin without having to capture it and drill mounting holes.

Tagging Sharks to Study the Twilight Zone

Former WHOI Joint Program graduate student and current University of Washington postdoc Camrin Braun and his team on the charter fishing vessel Machaca managed to tag two porbeagles, a relative of the goblin shark, about 30 miles east of Chatham, Mass. One was a female nearly seven feet long and weighing 270 pounds. A male came alongside the boat while the team was tagging her and, when they were finished, they quickly hooked the curious male, which measured 6.5 feet and weighed 230 pounds.

Both fish are now equipped with fin-mounted SPOT satellite tags, which will report their location each time they surface and can last up to five years. For the Ocean Twilight Zone team, the big predators are an important indicator of where mesopelagic animals are collecting deep below the surface. In short, the predator will go where the prey is.

Climate change threatens everyone’s favorite little fish

Cape Cod Times

The well-being of the colorful clownfish of “Finding Nemo” fame is closely tied to its habitat among the sea anemone, according to a 10-year study by an international team of scientists. The little fish does not appear to have the ability to adapt to the rapid environmental effects of climate change.
