Bad news for whales out of the Russian Far East: over 100 belugas are reportedly trapped in water between ice floes in the Chukotka region, cut off from the sea. Fishermen in the area—one of the poorest in Russia, bordering the Bering Sea—report that the white whales have been essentially boxed in by approaching ice [...]
Earth history is different from ordinary history: it’s much harder to nail down specific dates when everything happened millions of years ago and over huge, slow timescales. But it can be done, as shown by paleontologists who have pinpointed the exact date of the largest mass extinction to ever occur on earth. The end-Permian mass [...]
There’s a reason why scientists like to refer to the bluefin tuna as the “tigers of the sea.” The fish can grow to as much as 1,500 lbs. (700 kg), and can swim over 40 mph. Scientists who’ve tagged bluefin tuna in the wild to track their movements are amazed at how far the fish [...]
If you’re already daydreaming about your winter getaway to the tropics as the weather gets crisper and gloomier, consider adjusting your plans to include some swimming among the world’s coral reefs – not just because they offer an unparalleled panorama of underwater life, but also because they’re disappearing in the midst of coastal development. And [...]
Jellyfish: they’re the worst. From the dollar bill-sized jellies that wash up along the New Jersey shore to the deadly box jelly—the most toxic creature on the planet—no one likes jellyfish. And the bad news is that they may be taking over: as we pull fish from the sea, the jellyfish are left to flourish. [...]
One of the hottest points of debate on aquaculture is the effect that farmed fish might have on their wild cousins. Fish raised in a major aquaculture operation live in close, sometimes cramped conditions that are nothing like the open ocean. As a result, they can become victims of disease and parasites—just as for centuries [...]
Usually infectious disease is a one-way street—and human beings are at the end. New viruses begin in wild animals—like monkeys or chickens—before they mutate and cross over to human beings. HIV, West Nile, SARS, H5N1, H1N1—just about every new infectious disease over the past several decades had its start in animals before infecting people. “We’re [...]
Hypoxia sounds like a treatment that pop stars would use to keep from aging, but it’s actually one of the most serious—if underreported and invisible—environmental threats in the world. Hypoxia occurs when coastal waters become overloaded with nutrients like nitrogen and phosphorus—often from sewage or fertilizer running off the land. All those tasty nutrients encourage [...]
As we reported last month, one of the biggest obstacles to sustainable fish farming is that raising big, popular carnivores such as salmon and tuna requires us to fish – and overfish – far down the food chain, in the ranks of smaller species like anchovies. Those are the little critters the bigger fish like [...]
I’ve been spending much of the last couple of weeks doing radio and other media for my aquaculture cover in TIME. Everyone wants to know the same thing: is fish farming really sustainable? “It depends” isn’t a very satisfactory answer, so I’ve been focusing on the efforts of some in the aquaculture industry to raise [...]
