One-in-Four Chance the Fish You Just Ate Contains Plastic

Did you enjoy your fish with plastic dinner? There’s a one in four chance that fish did, indeed, contain plastic, reports Alternet:

Want a side of plastic with your fresh-caught salmon?


About a quarter of fish samples from markets in Indonesia and fresh off the boat in California are filled with plastic and debris such as clothing fibers, scientists at the University of California, Davis, have found.

While other research has found plastics in the bellies of popular dinner-plate items such as tuna and swordfish, this is the first study to link marine plastic ingestion directly to fish sold for human consumption.

“We knew fish ingest plastic, but we wanted to see if it was getting to consumers’ plates,” said Susan Williams, an ecology professor at UC Davis and a coauthor of the study.

The team looked at the guts and gastrointestinal tracts of 76 fish bought in markets in Makassar, Indonesia, and 64 fish bought from local fishers at the docks of California’s Pillar Point Harbor and Half Moon Bay fish markets south of San Francisco…

The Fukushima Freak Fish

Check this monster fish out:


It was caught by a fisherman off the Japanese Island of Hokkaido and is the largest wolffish ever recorded. At over 6 feet long (roughly double the normal size), the speculation is that it is essentially a mutant caused by radiation from the Fukushima nuclear plant.

Here’s the famous fisherman Hiroshi Hirasaka’s tweet celebrating his catch:

Ocean Fish Numbers on ‘Brink of Collapse’

The World Wildlife Fund is reporting that the number of fish in our oceans has halved since 1970 and now the fish population is on the brink of collapse. From the Economic Times:

The amount of fish in the oceans has halved since 1970, in a plunge to the “brink of collapse” caused by over-fishing and other threats, the WWF conservation group said on Wednesday.


Populations of some commercial fish stocks, such as a group including tuna, mackerel and bonito, had fallen by almost 75 percent, according to a study by the WWF and the Zoological Society of London (ZSL).

Marco Lambertini, director general of WWF International, told Reuters mismanagement was pushing “the ocean to the brink of collapse”.

“There is a massive, massive decrease in species which are critical”, both for the ocean ecosystem and food security for billions of people, he said. “The ocean is resilient but there is a limit.”

The report said populations of fish, marine mammals, birds and reptiles had fallen 49 percent between 1970 and 2012.

The real Alien vs. Predator is occurring right now in Antarctic waters


Dr. M via Deep Sea News:

In the freezing and dark waters of the Antarctic, two marine species are pitted against each other in a battle of survival. Each of the players in the evolutionary game is trying to avoid a permanent residency in the other’s stomach. One of the competitors, you may not be surprised by. The behemoth colossal squid can reach sizes of sizes of 495 kg (1091 lbs) and 4.2 meters (13.8 feet). The colossal squid’s competitor? The Antarctic toothfish reaching a puny 200 cm (6.5 feet) and 80 kg (176 pounds) in length at is biggest. Not exactly the size to take on the hooked tentacular mass of a colossal squid. Yet attacks and feedings of this two biological killing machines on each other occurs frequently in the natural world’s answer to Alien vs. Predator.

Remeslo and colleagues*** report 71 toothfish with deep wounds from squid beaks or scratches from suckers.

Fish Found To Equal Chimpanzees In Intelligence Test

Who knew that trout were so smart? A new study finds that coral trout actively seek hunting help from moray eels and collaborate to catch their prey, reports Wired:

Certain forms of collaboration are supposed to be so sophisticated that only the smartest creatures—namely humans and perhaps a few close relatives—are capable of them. Yet this exclusive club has a new and unexpected member: a species of fish, a class of animals seldom associated with high-level intelligence.

As demonstrated in a series of experiments published today in Current Biology, coral trout not only solicit the help of moray eels when they hunt, but also pick their hunting partners wisely. They know when they need help, and quickly learn which eels best provide it. It’s a seemingly simple yet surprisingly sophisticated cognitive trick.

Plectropomus leopardus 1

“Prior to our study, chimpanzees and humans were the only species known to possess both of these abilities,” said zoologist Alex Vail of England’s University of Cambridge.

The End of Fish

Cardona,Rizaljf5207 01Amy Novogratz and Mike Velings, co-founders of Aqua-Spark, an investment fund focused on sustainable aquaculture, write about the inevitable end of fish as we plunder the oceans, at the Washington Post:

People are getting more adventurous with how they eat, and when it comes to seafood, this means exhaustively looking to every exotic corner for the best, newest and tastiest fish. Also, the stuff is delicious. Seafood is a critical portion of more than 3 billion people’s diets. Already, 90 percent of U.S. seafood is imported.

This can’t last. The oceans are stretched, and certain fish species are approaching depletion. Leading scientists project that if we continue to fish this way, without allowing our oceans time to recover, our oceans could become virtual deserts by 2050. That’s just 36 years from now. Given that demand for seafood – along with the world’s population – is rising, don’t be surprised if this window closes even faster.

Over Demanding Market Affects Fisheries More than Climate Change

Via AlphaGalileo:

Fisheries that rely on short life species, such as shrimp or sardine, have been more affected by climate change, because this phenomenon affects chlorophyll production, which is vital for phytoplankton, the main food for both species.

Disclosed by the research “Socioeconomic Impact of the global change over the fishing resources of the Mexican Pacific” headed by Ernesto A. Chávez Ortiz, from the National Polytechnic Institute (IPN).

Work performed at the Interdisciplinary Center of Marine Sciences (CICIMAR) from the IPN, indicates that in the last five years there have been no “spectacular” changes attributable to climate change, what has affected the fishing resources more is the over demanding market.

“Globally, a great part of the fishing resources is being exploited to its maximum capacity, several have overpass its regeneration capacities and are overexploited” Chávez Ortiz points out.

The specialist at CICIMAR details that the research consisted in exploratory weather and fisheries analysis, and confirmed what has been intuitively said for a while: a lot of the variability in the fishing is due to climate change, the problem is that evidence hadn’t been found to prove it.

In 1947 a Live Fish Got Stuck in a Man’s Throat: Here’s How They Removed It

Here’s one from the archives: In 1947, medical personnel had to perform an emergency tracheotomy as part of a complicated procedure to remove a fish that had become lodged in the throat of an unlucky Malaysian man. The man’s family said that the fish had jumped from the man’s net and into his mouth, becoming lodged in his throat. Sounds about as likely as people who visit emergency rooms with rectums stuffed with “foreign bodies” that they “accidentally” fell on while naked, but what do I know? Stranger things have happened. Anyway, this is a pretty gruesome story…

Via Discover:

CASE REPORT: A Malay villager was admitted to the Malacca General Hospital on Feb.27, 1947, in a very distressed state, with laryngealobstruction.There was a marked stridor and retraction of the intercostal spaces. He was throwing himself about on the stretcher and was very dificult to examine, and of course quite unable to give any history.

Bioaccumulation Of Radiation In Fresh Water And Salt Water Fish After Chernobyl And Fukushima

Via AGreenRoad Project:

In the video above, we explore how to detect radiation in food. Why is this the ‘new normal’? With radiation accumulating in food, both animal, vegetable and fruit, we have no way of knowing how much radiation is in it. It is now becoming necessary to test ALL food before consuming it, due to the overwhelming magnitude of radiation contamination from many areas and nuclear facilities globally, not to mention depleted uranium weapons use.

Toxic radiation accumulates in water supplies after nuclear accidents. Radiation bioconcentrates in fish that live in fresh water and salt water. Runoff of fresh water from land which has been contaminated ends up contaminating oceans, and salt water creatures that live in it. Radiation can and does accumulate and bioconcentrate in fish and other creatures that live in the ocean, just like mercury, for example.

Most mass media stories about this subject downplay the hazards of nuclear radiation accumulating in animals or other foods.

Massive Serpent Found Off Coast Of Los Angeles

There are monstrous creatures that reside closer to the center of the earth than we do. The Huffington Post writes:

Marine science instructor Jasmine Santana was snorkeling off the coast of Southern California when she spotted something unusual on the sea floor. The curious researcher grabbed the limp marine animal by the tail and dragged it to shore.

The 18-foot oarfish is a significant find for any marine scientist, but, for CIMI researchers, it’s the “discovery of a lifetime.”

Oarfish are rarely seen since the long, bony fish tend to reside in deep-sea waters, only rising to the surface after their deaths. CIMI scientists believe the oarfish found in Catalina recently died of natural causes.
