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.
Why do northern and southern populations of Atlantic cod have different haemoglobin subtypes? A recent study upsets over 50 years of theory.
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!
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.
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!
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.
The impact of domestication can be detected within one generation in steelhead trout, and may involve adaptation to highly crowded conditions.
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?
In honour of our Mother’s Day theme week, we’ll look at how the environment experienced by parents during reproduction and their early life history influences their offspring.
Do Mother Nature a solid with these helpful tips & tricks to go green today!
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).
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!

Larval lobsters face potentially dangerous situations, find out how they fare against a couple important environmental stressors (salinity and pH changes).
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 equipment. Are there ways to reduce incidental bycatch and make longline fishing more sustainable?
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.
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.
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.
