Wicked Tuna Round Up and Shark Attack Tips

It’s week five for the fishermen in Gloucester, Massachusetts and a new challenge has presented itself: the great white shark! On this season of the Atlantic Bluefin Tuna, a single Bluefin can be worth up to $20,000…making it hard for any of the captains to stay out of the water. Let’s check to see how…

Fish Tank Kings: Pimp My Tank

Mat meets up with Allan Marshall who runs biological operations at the Florida Aquarium.  Allan wants a fresh take on an old exhibit and is interested in showcasing rarely seen deep sea fish. Mat knows of a submarine in the Caribbean and gets Allan excited for the unique adventure.  Additionally, Mat has promised a repeat…

Shark Men: What’s in the Chum?

Want sharks? Better serve chum. One of the most effective ways to draw sharks in for capture and research is chumming. Cage diving tours, researchers and fishermen use a bloody mixture of fish products dropped into the water to draw sharks in for catching and viewing. Chum is one of the most important tools on…

Seal Island

© Africa Wildlife Films In South Africa’s False Bay, Cape Fur seals gather by the tens of thousands to escape the ocean’s largest predatory fish – the great white shark. Here at Seal Island, seals rest and breed between migrations into the rich fishing grounds beyond. But these seals must run a gauntlet of shark-infested…

Tagging and Tracking Whale Sharks

Researchers often use technology to track the movements of animals. And although whale sharks are the planet’s largest living fish, relatively little is known about these ocean travelers. Tagging animals can help communicate key information about these unpredictable and mysterious marine giants – like distinct migration patterns, feeding behaviors and climate change responses.  Not all tracking…

Swimming with Sharks

© NGT Written by Dr. Brady Barr, Dangerous Encounters: Eleanor Roosevelt once said that you should do one thing every day that scares you.  Somedays are certainly bigger than others, and today was going to be a big one for me —though I had no idea going into it. From working around dangerous snakes to…

Aggressive Bull Sharks

One of nature’s deadliest predators, the bull shark, can spend a lot of time in fresh water. They’ve been spotted swimming thousands of miles up the Amazon River and jumping river rapids in Nicaragua. The secret to this adaptation is their ability to retain salt inside their bodies – the bull shark’s kidneys and special gland…

Whale Sharks Vulnerable to Boat Strikes

Because whale sharks sometimes filter feed along the ocean’s surface, they are vulnerable to boat strikes. But determining how to protect a highly migratory species from vessel-related injuries is a challenging problem. Rafael de la Parra, Project Domino research coordinator and biologist, told me that whale sharks “swim slowly, filtering the plankton-rich seawater… so they are…

Aerial Survey of Whale Sharks

Just off the northeastern tip of the Yucatan Peninsula is the largest whale shark aggregation site in the world. And marine biologists are conducting regular aerial surveys of this feeding zone to document key information about these wild ocean travelers…. According to Dr. Alistair Dove, Senior Scientist at the Georgia Aquarium, aerial surveys compliment other…

Chemical Ecology Studies May Reveal How Whale Sharks Find Food

While little is known about the world’s largest fish, most experts agree that whale sharks are usually solitary creatures. But each summer these amazing marine fish migrate great distances to select feeding aggregation sites. But how do they find food in the vast ocean? Chemical ecology studies may soon answer this puzzling question. Georgia Aquarium…
