Release the Robots! How researchers are studying stressed sharks
Have you ever wondered what happens to a fish after you catch and release it? Does its behavior change? Does it survive after it’s been taken out of the water? Researchers are now using remote controlled robots to answer these very questions! Grace CasselberryI am currently a Marine Science and Technology Doctoral student at the […]
The Dynamic Duo: Application of Complementary BRUVs and eDNA to Marine Fish Assemblages
Innovations in waterproofing cameras and DNA analysis have led marine scientists to apply these methods in unique ways in recent decades. Through the use of BRUVs and eDNA this article looks at fish assemblages in Jurien Bay Marine Park in Western Australia to compare these methods individually and combined. When BRUVs and eDNA were both […]
The Gulf of Mexico Triangle: Assessing Movements of Large Pelagic Fish Across Multiple National Boundaries
Pelagic predators or difficult to manage due to their vast migrations through through multiple countries jurisdictions and international waters. In order to effectively manage these species multinational agreeements are required. However, collecting movement data for species that travel long distances is difficult to collect. Here, researchers look at the movements between countries of 8 species […]
Tracking the Bay’s Rays: Cownose ray migration along the Atlantic coast
If you’ve ever tickled the back of a stingray in an aquarium’s touch tank, you’ve likely introduced yourself to a cownose ray. Despite their popularity in aquaria throughout the U.S., little is known about the movements of these fish in the wild. Grace CasselberryI am currently a Marine Science and Technology Doctoral student at the […]
The shark and the side salad
Everyone knows all sharks are carnivores. Or are they? Grace CasselberryI am currently a Marine Science and Technology Doctoral student at the University of Massachusetts Amherst. I use acoustic and satellite telemetry to study the spatial ecology of lemon, nurse, Caribbean reef, and tiger sharks in St. Croix to better understand habitat selection, residency, and […]
When having babies, is quantity or quality better?
Evolution is riddled with trade-offs. One of the classic examples is how to spread maternal resources – is it better for an individual to have a lot of babies or invest more into only one or two? Researchers examined how this trade-off plays out in the marine world by comparing the competing reproductive strategies of […]
Stuck in the middle with you: The trophic ecology of Caribbean reef sharks and large teleost coral reef predators
We often think of sharks as the top of the ocean food web, chowing down on seals and big fish to their heart’s content. That is often not the case! Where does the Caribbean reef shark fall in this hierarchy? Let’s find out. Grace CasselberryI am currently a Marine Science and Technology Doctoral student at […]
Big Momma: bigger fish are better moms
What makes a fish a good mom? Read here to see why scientists now think that big fish moms are the best fish moms. Ashley MarranzinoI received my Master’s degree from the University of Rhode Island where I studied the sensory biology of deep-sea fishes. I am now working with the South Carolina DNR at […]
Citizen Science and Undersea Stars: The Value of Photographs to Global Megafauna Biology
Check out this article about how tourist pictures of whale sharks are helping scientists learn about whale shark populations around the globe! Matthew LarsenI am a second year master’s student at Coastal Carolina University in the Abel Lab. My interests focus on the ecology and life history of large marine megafauna with a central focus […]
Top 5 Highlights of Deep Sea Exploration in 2017

Megan ChenI graduated with a Masters of Coastal & Marine Management from the University of Akureyri in Iceland, and am currently working at the Smithsonian Institution’s National Museum of Natural History in Ocean Education. I am interested in smart […]
Invasive seagrass changes fish community in the US Virgin Islands
Seagrass meadows provide food and habitat for a variety of fish species. Juvenile fish are particularly dependent on the meadows, for the shelter they provide from predators. In the Caribbean, several native seagrasses might be found in the same shallow estuary or coastline, forming a patchwork of meadows that support a variety of different fish […]
Seaweed antioxidants protect fish too
A new study suggests that feeding fish small amounts of antioxidant-rich seaweed can protected them from environmental challenges. Brittney G. BorowiecBrittney is a PhD candidate at McMaster University in Hamilton, ON, Canada, and joined Oceanbites in September 2015. Her research focuses on the physiological mechanisms and evolution of the respiratory and metabolic responses of Fundulus […]
Candidate compass genes in fish
A team of American researchers use next-generation sequencing to ask: “magnetoreception, how does it work?” Brittney G. BorowiecBrittney is a PhD candidate at McMaster University in Hamilton, ON, Canada, and joined Oceanbites in September 2015. Her research focuses on the physiological mechanisms and evolution of the respiratory and metabolic responses of Fundulus killifish to intermittent […]
Sea lampreys: grow faster = grow male
A new study suggests that growth rate may determine if lampreys, an invasive fish in the Great Lakes becomes male or female. Read to find out more! Megan ChenI graduated with a Masters of Coastal & Marine Management from the University of Akureyri in Iceland, and am currently working at the Smithsonian Institution’s National Museum […]
It’s a trap! African penguins impacted by climate change
Young penguins living along the southwestern coast of Africa typically follow cool, nutrient rich water to find food as they grow up. This used to lead them to ‘delicious’ fish such as anchovies and sardines. However, in this ecosystem – the Benguela Upwelling Zone – climate change and overfishing have reduced these fish populations. This […]
Now we got bad blood: Oxygen binding is not affected by haemoglobin subtype in Atlantic cod
Why do northern and southern populations of Atlantic cod have different haemoglobin subtypes? A recent study upsets over 50 years of theory. Brittney G. BorowiecBrittney is a PhD candidate at McMaster University in Hamilton, ON, Canada, and joined Oceanbites in September 2015. Her research focuses on the physiological mechanisms and evolution of the respiratory and […]
Grunts and Gnathiids: One Fish’s Daily Migration to Escape Parasites?
Animals move for a number of reasons. The French grunt leaves the coral reefs at night for seagrass. A group of scientists proposes and provides good evidence for why they might do that! Read on to discover whether they’re leaving to avoid being parasitized? Rebecca FlynnI am a graduate of the University of Notre Dame […]
Pet trout: domestication rapidly alters gene expression
The impact of domestication can be detected within one generation in steelhead trout, and may involve adaptation to highly crowded conditions. Brittney G. BorowiecBrittney is a PhD candidate at McMaster University in Hamilton, ON, Canada, and joined Oceanbites in September 2015. Her research focuses on the physiological mechanisms and evolution of the respiratory and metabolic […]
Rip Rap Sill: The Best of Both Worlds
The hybrid shoreline stabilization method called rip rap sill combines rock structures with native vegetation. This study found that fish biodiversity and abundance in rip rap sills was more similar to a native marsh than a built rip rap. Kari St.LaurentI received a Ph.D. in oceanography in 2014 from the Graduate School of Oceanography (URI) […]
Changing with the environment: how resilient are coral reef fish?
Coral reef fish are some of the most sensitive animals to climate change. How will coral reef fish respond to predicted increases in temperature and carbon dioxide? Do they have the ability to adapt to future conditions or is it already too late? Sean AndersonI am a first year MS candidate at the University of […]
