The behavior, used by wolves and orcas to run down fast prey, is rarely seen in fish.
In August 2012, Douglas Bastos, then a graduate student at Brazil’s Instituto Nacional de Pesquisas da Amazônia, was exploring a remote waterway in the Amazon rainforest when he came across a small lake teeming with electric eels. Continue reading
Known locally as ‘Stalin’s Red Army’, an invasion of king crabs from Russia created a lucrative industry, and difficult choices
The Norwegian fishing village of Bugøynes, 310 miles north of the Arctic Circle and a frigid, dark place for much of the year, was on the edge of ruin.
Work was scarce. Years of overfishing and mismanagement had stymied cod quotas. Boats lay idle in cold waters. Those who chose to stay were forced to rely on what meagre wages they could still muster from fishing and processing. Continue reading
When you genuinely smile and then recoil a moment later, you are responding to what this artist wants you to see and then understand. The animation is brilliant and its short message on how ocean litter/marine plastic is harming marine life is ominous. The Artist Statement that accompanies it is not required reading, but it is there for the taking:
Two years ago, an experience on a small island inTaiwan changed my life. It was the closest I’d lived to the sea, being only a ten minute drive away. Everyone can enjoy the beach with its white sand and turquoise ocean. At the time, I went snorkeling almost every week. Seeing such alluring tropical fish and coral reefs still lingers in my mind. However, I also cannot forget the scenes of tons of human waste lying around the shore as if it was a part of nature. Continue reading
Of all the ways to transition to vegetarianism, which I am on snail’s pace doing, I just realized that the one form of animal protein that I have completely eliminated without thinking about it is fish. I cannot remember planning on doing this, but at this moment I cannot remember the last time I ate fish. It may have been 2016. But I have been conscious of the sensation every time I am grocery shopping that I avoid the fish.
Sushi was my favorite treat of a meal years ago, and while living in India we were as much pescatarian as vegetarian. But that changed with a growing awareness of the challenges related to regulating the world’s seas. So I quit eating things from it. Jennifer E. Telesca, writing in Yale e360, does not make me feel any better about this–as a data point I am exactly of zero relevance compared to the total market size–but I am gratified to see a book on a topic that will help me better quantify the reasons why exiting the market for fish is a priority:
The international commission responsible for managing Atlantic bluefin — prized for high-quality sushi — is failing to protect this magnificent fish. The regulators’ focus on fishing industry profits points up the need to change the way we view, and value, the lives of wild creatures.
In 2010, after years of global headlines highlighting the runaway harvest of bluefin tuna in the Mediterranean Sea and eastern Atlantic Ocean, the international regulatory agency managing this endangered fish capitulated. It cut the total allowable annual catch to 12,900 metric tons, the lowest level recorded. For the world’s most valuable fish, coveted as the most succulent sushi on the planet, a return to plenty looked promising. Continue reading
Companies like Impossible and its competitor Beyond Meat have gotten most of the attention in our pages for plant-based meat-like products, but when it comes to alternative seafood our stories have mainly focused on invasive species, or on farming kelp or on seaweed farming. Thanks to Mother Jones for stretching our attention to the alternatives to fresh caught or even farm-raised seafood that simulates the kinds of fish that have been over-harvested:
This is why we can’t have nice things.
Do you love burgers—but not the animal cruelty and environmental degradation that go into making them? I come bearing good news: Someday, you might be able to get your meat fix, without all that bad stuff. Scientists can now grow animal flesh, without raising—or in most cases killing—an animal. This food, called “lab-grown meat,” “cell-based meat,” “cultured meat,” “cultivated meat,” “clean meat,” or as comedian Stephen Colbert jokingly called it in 2009, “shmeat,” has set off a flurry of media attention in recent years. Dozens of lab-grown meat companies have materialized, most aiming to solve the problems associated with large-scale beef, pork, poultry, and seafood production.
Finless Foods, a 12-person food-tech startup founded in 2017 and based in Emeryville, California, claims to be the first company to focus on lab-grown fish, although a handful of other startups have since joined them. In October, 28-year-old Finless Foods co-founder Mike Selden gave me a tour of their facility, and I dished about it on the latest episode of the Mother Jones food politics podcast Bite:
Selden and his co-founder Brian Wyrwas, both products of an agricultural biochemistry program at UMass Amherst, started the company, he says, to “make something good.” Continue reading
Thanks to National Public Radio (USA) for this warning:
If you’re in the mood for a tuna poke bowl or an old-school tuna niçoise salad, here’s a tip: Don’t hit up the Greenhouse Tavern in Cleveland. It has been nearly six years since chef Jonathon Sawyer became a “tuna evangelist” after attending a meeting of like-minded chefs at the Monterey Bay Aquarium. It was there that he made the decision to forgo tuna — both in his personal life and on the menus at all four of his restaurants.
It wasn’t always easy. Turning down the chance to eat famed chef Eric Ripert’s mouthwatering thin-sliced tuna over a foie gras torchon took some Superman-like strength, but for Sawyer, the mission is an important one. He’s not trying to get people to give up tuna altogether. Rather, he’s trying to raise awareness of the sheer quantities that are coming across our collective plates and serve as a gentle warning that all that fish is coming from a limited resource.
It turns out that his effort is hitting a seafood sustainability bull’s-eye. Continue reading
Thanks to the Guardian for this story about Belize’s marine conservation efforts and how they can serve as a model for other countries.
Fish stocks are stable and reef health improving, in part thanks to Belize’s substantial ‘no-take’ zones. Now greater legislation is needed to secure progress
Across the turquoise water by the mangrove, forest ranger Allan Halliday spots a fishing skiff. “We’re going over to say hello,” he says, before abruptly changing the boat’s direction. But his real task is to check the couple on board have the license to fish in this part of the Port Honduras Marine Reserve, one of nine designated zones in Belize.
“We aren’t complaining but others do,” says Alonzo Reymundo, of the rules that now restrict Belize’s 3,000 commercial fishers to two geographic areas each. He and his wife Anselma have been fishing off southern Toledo for 30 years and their boat is laden with 50 or so pounds of shrimp – more than enough, he says, flashing his license. Today’s catch will be sold as bait and fetch around 330BZ$ (£135), he says.
But not all encounters are as friendly for the rangers from the Toledo Institute for Development and Environment (Tide), whose job includes enforcing the managed access (MA) programme that since 2016 has given traditional fishers the rights to secured grounds if they obtain licenses and report their catch. Illegal fishing has declined, says Halliday, but at night there are illicit incursions from Guatemala and high-speed chases around the reserve’s 500-square miles of pristine sea – a vast space to monitor for just four rangers alternating shifts at their station on Abalone Caye.
Covering all of Belize’s waters, the MA scheme is unique, says fisheries administrator Beverly Wade. “Belize is the only country in the world that has successfully divided all its territorial waters, including functional fishing waters. We direct all fishermen into two of nine areas to build an architecture from the ground up, where a constituent takes ownership of resources because their livelihood depends on it.”
The programme is just part of a groundbreaking approach to ocean protection that has won the tiny country in Central America a reputation as a world leader. Continue reading
Paul Greenberg, author of The Omega Principle: Seafood and the Quest for a Long Life and a Healthier Planet (Penguin Press), is making the rounds with an important argument; get the short version here in the Guardian:
Omega-3 is one of our favourite supplements – but a huge new study has found it has little or no benefit for heart health or strokes. How did it become a $30bn business?
The omega-3 industry is in a twist. Again. Last week, Cochrane, an organisation that compiles and evaluates medical research for the general public, released a meta-analysis – a study of studies – to determine whether or not omega-3 pills, one of the world’s most popular dietary supplements, reduced the risk of coronary heart disease. After comparing 79 trials involving 112,059 people, the researchers could find “little or no difference to risk of cardiovascular events, coronary heart deaths, coronary heart disease events, stroke or heart irregularities”.
I can’t say that I was particularly surprised. Over the past 15 years, more than 20 studies have shown a similar lack of effect. But what does surprise me is how we continue to look at the world of fish and seafood through the amber lens of a fish oil capsule. Omega-3s do something in our bodies – and probably something important. But without the larger context of the marine organisms that contain them, omega-3s get lost in the noise of human metabolism and modern marketing.
Thanks to Damian Carrington, Environment editor at the Guardian, for bringing this to our attention:
Global fish production is at record levels thanks to fish farming, says the UN FAO, but much is wasted and many species are worryingly overfished
One in three fish caught around the world never makes it to the plate, either being thrown back overboard or rotting before it can be eaten, according to the UN Food and Agriculture Organization. Continue reading
Low light imaging data being used to expose unregulated and unreported fishing on the high seas
New data is being used to expose fleets of previously unmonitored fishing vessels on the high seas, in what campaigners hope will lead to the eradication of illegal, unregulated and unreported fishing.
Global Fishing Watch (GFW) has turned low light imaging data collected by the US National Oceanic and Atmospheric Administration (NOAA) into the first publicly available real-time map showing the location and identity of thousands of vessels operating at night in waters that lie beyond national jurisdiction.

Thanks to for this story about how a Robotic Fish Moves Like The Real Thing — So It Can Observe The Real Thing:
Scientific advancement: It’s all in the wiggle.
OK, it’s a lot more complicated than that. But when a team of researchers at MIT unveiled their robotic fish Wednesday, one of the keys they emphasized was the graceful undulation of the prototype’s tail — which, besides being rather eye-catching, serves a crucial role in the robot’s ultimate mission: giving scientists the ability to unobtrusively observe marine wildlife remotely.
“Because the fish moves through undulating movement rather than thrusters, the impact it has on how the water moves around it is much more like what is expected of physical fish,” Daniela Rus, director of the school’s Computer Science and Artificial Intelligence Lab, tells NPR. Continue reading
I’ve posted previously about the lionfish invasion that is threatening coral reef and other marine ecosystems throughout the Caribbean, Gulf of Mexico, and Southern Atlantic Seaboard of the United States.
Much has been made of the spectacular invasive success of the two species of Indo-Pacific lionfish that have established themselves throughout the Wider Caribbean. Not only are the invaders being found at population densities more than ten times those typical in their native range, but they also have been found to grow more rapidly, reaching sexual maturity more quickly, and growing to greater size than do their Indo-Pacific cousins.
Several studies have looked at the genetic make-up of invasive lionfish and have concluded that the populations found in the Gulf of Mexico, Caribbean, and Southeastern seaboard of the United States are all closely related, stemming back to fewer than ten females. Continue reading
Thanks to Nancy Matsumoto and the folks at the salt, over at National Public Radio (USA):
It’s the end of only the first week of the official Atlantic sturgeon fishing season on the St. John River in New Brunswick, Canada. But the two fishermen who supply Cornel Ceapa’s Acadian Sturgeon and Caviar company have already landed close to half of the season’s catch. Continue reading
Cod seems as good as any other creature to feature in a redemption story. The editor of the Environment section at the Guardian shares good news on one lucky population of cod that got the attention they needed, seemingly just in time:
A recovery from near total collapse has led North Sea cod stocks to be labelled as sustainable by the Marine Stewardship Council for the first time in 20 years Continue reading
We’ve mentioned Cabo Pulmo here several times in the context of marine conservation, as well as from a personal visit. Although I still haven’t had a chance to go out on a scuba diving expedition here, a couple weeks ago Jocelyn and I were able to accompany some Villa del Faro guests on a snorkeling trip outfitted by Cabo Pulmo Sport Center, which is run by members of the Castro family mentioned in the posts linked above. The tour took two hours, but I’ve condensed the experience into almost fifteen minutes of video that I took on a rented GoPro:
Thanks to contributor Phil Karp for sharing this great example of how peer-peer knowledge exchange can help to replicate and scale up innovative solutions.
Experience from around the world shows that managing fisheries and marine resources works best when responsibility is placed in the hands of local communities. This is particularly true in low-income countries, where there is often limited capacity and infrastructure for fisheries management and conservation.
Locally Managed Marine Areas (LMMAs) are areas of ocean managed by coastal communities to help protect fisheries and safeguard marine biodiversity. Found throughout the world’s tropical and subtropical seas, and encompassing diverse approaches to management and governance, their sizes and contexts vary widely, but all share the common theme of placing local communities at the heart of management.
We’re always looking for well-balanced discussions on innovative but occasionally controversial forms of food production. Open ocean aquaculture is an example, and we appreciate the Food & Environment Reporting Network for offering just that, suggesting that many of the environmental concerns with aquaculture are mitigated by using deep water locations.
President of the New Orleans–based Gulf Seafood Institute, Harlon Pearce knows better than anyone that wild fisheries alone can’t supply U.S. consumers’ growing demand for fish. Which is why he’s doing his best to bring everyone to the table to achieve one goal: farming the Gulf of Mexico. Continue reading
Thanks to Joanna Klein and the Science section of the New York Times for this explanation of a full moon mating phenomenon:
Every year, thousands of little fish ride waves onto Southern California’s beaches at night to lay and fertilize eggs. High up in the sand, they squirm, wriggle and wrap around one another. As they dance beneath the moonlight, the beach transforms into a twinkling tapestry of spawning silver bodies. It’s known as the grunion run, and within a few hours, the show is over. Continue reading
