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.
We know that larger female fish produce more eggs, but does this really mean they produce more young that grow into the next generation?
Lox and lice. Not a combination of critters you envision when planning your Sunday brunch. Unfortunately, an increase in drug resistant sea lice is threatening both wild and farmed salmonid populations.
Whale sharks have become an increasingly popular tourist attraction, but much of their life history remains largely unknown. This study sets off to observe whale sharks around Darwin Island to help understand more about their habitat use, population size, and seasonal appearances. And what they find is a whole lot of pregnant whale sharks.
Seafloor trawling inevitably captures more than the species it is targeting. This means that when the remaining fishes line up at the buffet table, the options they have to choose from may be different than what they like to eat. In this article, Johnson et al., investigate whether two fish species in the Irish Sea are going hungry under different trawling conditions.
Coral reefs are composed of hundreds of different species, who all use different acoustics to communicate, just like we use different languages around the world to communicate. Researchers set out to better understand and record the language of fishes in hopes of building a species-specific soundscape of the coral reef community.
