Sharks & Other Fish
Listening to fish with passive acoustics
Scientists at the Woods Hole Oceanographic Institution and NOAA Fisheries combine forces to adapt technologies used to detect marine mammals for fisheries management.

A robot camera has been used in UK seas for the first time to monitor the behaviour of basking sharks. WHOI’s SharkCam was deployed off the west coast of Scotland where the sharks gather to breed after migrating from waters off west Africa.
A Marine Heatwave Is Warming Up The Ocean Along The East Coast
Here & Now‘s Jeremy Hobson talks to Glen Gawarkiewicz, an oceanographer at Woods Hole Oceanographic Institution, about why the ocean temperatures are warming as well as what it means for ocean life and weather patterns.
Hot ocean waters along East Coast are drawing in ‘weird’ fish and supercharging hurricane season
Warm waters are a major concern with Hurricane Isaias forecast to ride up the Eastern Seaboard. Glen Gawarkiewicz, an oceanographer at WHOI, describes Gulf Stream fish being caught off Block Island, R.I., in January 2017 and increases in the “rate and amount” of species like mahi-mahi passing through.
Shark sightings are up, along with ocean temperatures. Here’s what to do if you encounter a shark.
“If they preyed on humans, there would be humans dead everywhere,” said Simon R. Thorrold, a biologist at WHOI in Massachusetts. “It would be a bloodbath out there.”
Ocean Encounters: Sharks!
Sharks are one of the most iconic, and feared, groups of animals in our wild ocean. Like other apex predators, they play a crucial role in the ecosystem they call home. Join us to learn about sharks and their behavior and role in a healthy ocean with shark biologist Greg Skomal, Massachusetts Division of Marine Fisheries, and WHOI ocean ecologist Simon Thorrold.

Simon R. Thorrold, a senior scientist in the biology department at WHOI in Falmouth, Mass., said it was “not crazy surprising” that a signal was picked up.
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.

Whale sharks are endangered, hard to track, and minimally protected, but thanks to a new tracking study and a lot more information, scientists have been able to monitor the movement of these gentle ocean giants.
Climate change threatens everyone’s favorite little fish
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.
Clownfish can’t adapt to rapid environmental changes
The beloved anemone fish popularized by the movies “Finding Nemo” and “Finding Dory” don’t have the genetic capacity to adapt to rapid changes in their environment, according to a new study in the journal Ecology Letters.

A new study of whale shark movements near a known hotspot in the Red Sea sheds light on their behaviors and could help inform the conservation efforts of the largest known fish, which can reach lengths of 40 feet or more.

Read MoreBasking sharks filmed by an AUV for the first time
Three things you may not know about basking sharks:
1. The basking shark is the 2nd largest fish in the ocean.
2. While it’s gaping mouth can fit a human, it filter feeds on tiny plankton.
3. WHOI’s SharkCam captured the first Autonomous Underwater Vehicle (AUV) footage of basking sharks.

Scientists Team With Fishermen on Tracking Technology
Scientists from the Center for Coastal Studies and the Woods Hole Oceanographic Institution are working with local commercial fishermen to install video monitoring equipment on gillnets.
Blue sharks use eddies for fast track to food
Blue sharks use large, swirling ocean currents, known as eddies, to fast-track their way down to feed in the ocean twilight zone—a layer of the ocean between 200 and 1000 meters deep containing the largest fish biomass on Earth, according to new research by the Woods Hole Oceanographic Institution (WHOI) and the Applied Physics Lab at the University of Washington (UW).

An autonomous underwater vehicle (AUV) known as the REMUS SharkCam has been used in the UK for the first time to observe the behaviour of basking sharks in the Inner Hebrides, off the west coast of Scotland.

Read MoreSharks & Other Fish
Fish serve important ecological and economic functions. Ecologically, they are both predator and prey, providing food for other animals, and serve to keep the numbers of prey species in check, many of which could destroy important ecosystems such as coral reefs and mangroves if their numbers are allowed to grow.

Read MoreFlounder Now Tumor-free in Boston Harbor
In the late 1980s, more than three-quarters of the winter flounder caught in Boston Harbor – one of the most polluted harbors in America – showed signs of liver disease, many of them with cancerous tumors. But now, a scientist at Woods Hole Oceanographic Institution (WHOI) has documented a dramatic rebound in flounder health spurred by decades of remediation efforts, including a $3.8 billion project to construct a sewage treatment plant and a 9.5-mile discharge tunnel with a 6,600-foot-long outfall diffuser. The findings appear in the Nov. 20, 2018 issue of the journal Diseases of Aquatic Organisms.
