How just 3% saves 50%: Small expansions of protected areas in “shark hot spots” could save HALF of currently endangered Sharks, Skates, and Rays

The old adage of, “work smarter, not harder” even applies to shark conservation…read on to learn how targeted expansion of marine protected areas could better protect more than 50% of imperiled shark species around the globe. Amanda IngramAmanda Ingram is a Masters of Marine Affairs Graduate Student at the University of Rhode Island. She earned […]

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 […]

Should all shark fishing be banned?

It might seem like a no-brainer to ban shark fishing as well as the sale and trade of shark products. But scientists wonder: is there a more effective management strategy? Read more to find out! Megan ChenI graduated with a Masters of Coastal & Marine Management from the University of Akureyri in Iceland, and am […]

What can tuna tell us about mercury emissions?

North America’s mercury emissions have declined over the last two decades. Researchers have found a connection between the declining emissions and the mercury level in tuna. Read more to find out how they made this link and what it could mean for the future. Victoria TreadawayI am a PhD candidate at the Graduate School of […]

Let’s Ghost Fishing for Halloween!

Ghost fishing is ghastly because it creates underwater graveyards for wildlife. The authors covered here wrote a new review of gear entanglement among mammals, reptiles, and sharks. Find out what they discovered by reading today’s post! Rebecca FlynnI am a graduate of the University of Notre Dame (B.S.) and the University of Rhode Island (M.S.). […]

Why do restaurants join sustainable seafood labelling programs?

Why do some restaurants join sustainable seafood eco-labeling programs? A new study identifies some motivating factors that can help the continued expansion of these programs to enhance their ability to harness consumer demand and encourage positive change in seafood production. Megan ChenI graduated with a Masters of Coastal & Marine Management from the University of […]

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.

Ancient swimmers: Greenland sharks live for centuries

Using radiocarbon dating, scientists have discovered that the Greenland shark can live longer than any other known vertebrate. How long have some of these individuals been alive?

You look like your mom: parental effects in Atlantic salmon

Trawling selects for faster fish

A new study suggests that differences in exercise performance make some individuals more vulnerable to capture by trawling than others, and that this may drive the evolution of commercially-important fishes (Photo: Wikimedia). Brittney G. BorowiecBrittney is a PhD candidate at McMaster University in Hamilton, ON, Canada, and joined Oceanbites in September 2015. Her research focuses […]

How to Stop Dragging Our Assets: The World’s First Fishery Habitat Quota

Setting limits on fish catch is standard practice in fisheries management. For the first time in history, limits on habitat damage was introduced in 2012 for the groundfish bottom trawl fishery in British Columbia. Was it successful? Read to find out! Megan ChenI graduated with a Masters of Coastal & Marine Management from the University […]

Northern Atlantic cod make an epic comeback

The collapse of Northern Atlantic cod was the textbook example of how overfishing can lead to a population crash. Decades after a moratorium was established, the cod are finally making a recovery. Find out why! Megan ChenI graduated with a Masters of Coastal & Marine Management from the University of Akureyri in Iceland, and am […]

Tampering with the food web: what do changes in jellyfish and menhaden populations mean for the ecosystem?

Article: Robinson, K.L., J.J. Ruzicka, F. J., Hernandez, W.M. Graham, M.B. Decker, R.D. Brodeur, and M. Sutor. 2015. Evaluating energy flows through jellyfish and gulf menhaden (Brevoortia patronus) and the effects of fishing on the northern Gulf of Mexico ecosystem. – ICES Journal of Marine Science, doi: 10.1093/icesjms/fsv088 Background We’ve all grown up learning “who […]

Tiny lobsters, big problems.

Larval lobsters face potentially dangerous situations, find out how they fare against a couple important environmental stressors (salinity and pH changes). Sarah GiltzI am a doctoral candidate in Ecology and Evolutionary Biology at Tulane University. My research focuses on the larval dispersal and development of the blue crab in the Gulf of Mexico. When not […]

Untangling the issues with longline fishing

Longline fishing has been used for decades as a way to catch large amounts of commercial fish. Though effective in capturing target fish, longlines unintentionally snag and kill millions of other marine species. Aside from being caught themselves, marine mammals (i.e. dolphins and killer whales) may eat target fish off the hooks and destroy fishing […]

North Sea fish stick to warming shallows rather than cooling off at depth

Models based on historical survey data indicate that with long term warming trends, fish distributions in the North Sea will remain at nearly the same depths while abundances across species may change considerably. Lis HendersonI am studying for my doctoral degree at the Stony Brook University School of Marine and Atmospheric Sciences. My research addresses […]

Technology for Turtles: TurtleWatch Program to Protect Sea Turtles and Assist Fishermen

A technology that both benefits fishermen and helps prevent sea turtle bycatch? Yes, please! The great news is that it exists! And now, it has been updated to include leatherbacks. Read on to learn more about TurtleWatch. Rebecca FlynnI am a graduate of the University of Notre Dame (B.S.) and the University of Rhode Island […]

What would coral reefs be like without human impact?

One would think that an isolated reef ecosystem shielded from the influence of people would provide an ideal benchmark against which other coral reefs can be compared. But in a recent study, researchers found it isn’t that simple. Valeska UphamFor my fisheries and aquatic science PhD I am working on how to tank raise urchins […]

Are bigger moms better moms?

We know that larger female fish produce more eggs, but does this really mean they produce more young that grow into the next generation? Sarah GiltzI am a doctoral candidate in Ecology and Evolutionary Biology at Tulane University. My research focuses on the larval dispersal and development of the blue crab in the Gulf of […]
