11:05 AM May 30, 2012 | 75 -3459- California tuna study: Radioactive contamination raises public health concerns - spent less than a month in waters near Japan - turtles, sharks, birds also at risk[i]
Other highly migratory species (e.g., turtles, sharks, and seabirds) that forage near Japan may assimilate radiocesium and transport it to distant regions of the north and south Pacific
10:29 AM Oct 19, 2013 | 146 -6568- Sailor: After we left Japan, it felt as if the ocean itself was dead - Nothing alive for over 3,000 miles - no longer saw turtles, dolphins, sharks, birds - saw one whale, it appeared helpless with big tumor on head
-6739.3- Something odd in Pacific; Sea creatures acting strangely, species turning up where rarely seen - L.A. Lifeguard: Used to be two shark sightings a year, now it’s two a day (VIDEOS) Nov 27, 2013
03:00 PM Oct 23, 2014 | 777 -8472- Pacific: Dead for thousands of miles between U.S. & Japan - Like sailing in a dead sea… everything’s all gone - Just talking about it makes me feel like I want to cry - No birds, no fish, no sharks, no dolphins, no turtles, nothing (AUDIO)
KRON, Apr 13, 2017 (emphasis added): A troubling trend – sharks and other marine life are washing up on Bay Area shorelines. First, it was Santa Cruz, and now, it’s the Peninsula… dead sharks were found washed up Thursday morning… Experts say similar reports are coming in every day, and it’s not clear why all the marine life is washing up… [T]he Pelagic Shark Foundation in Santa Cruz is pleading with Bay Area people to be alert on walks and report to them immediately.
KRON transcript, Apr 13, 2017: “There are a lot of small dead sharks that have been found, just today… it’s just not clear why all the marine life is washing up like this.”
Santa Cruz Sentinel, Apr 8, 2017: [Sean Van Sommeran, Pelagic Shark Research Foundation executive director] said there have been too many white-shark strandings this year throughout coastal Northern California… he is frustrated about the lack of help for stranded sharks. “There’s been over 100 dead this year in San Francisco, San Mateo, Oakland and Berkeley Aquatic Park… We get them all the time in the San Francisco Bay Area.”
California Department of Fish and Wildlife, Apr 14, 2017: The carcass of a young great white shark was recovered on April 8 near Pleasure Point in Santa Cruz… It died of multiple organ failure, with major lesions in the brain, liver and heart… Unidentified microorganisms were observed in the fluid surrounding the brain and heart. Additional testing is underway to attempt to identify these pathogenic organisms
CBS San Francisco, Apr 11, 2017: Marine Biologist Giancarlo Thomae said a necropsy found an infection had damaged the shark’s brain and other organs. “The species of the bacteria that contributed to the shark’s death is unknown at this time… However, the brain did have many lesions. In additional to that the shark’s heart and liver also showed damage, so we can conclude that the immune system of the shark was also compromised.”… Die-offs of leopard sharks and other types have occurred in the San Francisco Bay in the last two years.
KXTV, Apr 14, 2017: Washed up Great White Shark died of organ failure… Biologists believe the shark died of multiple organ failure, with major lesions in the brain, liver and heart. Unknown microorganisms were also found and additional testing is being done.
NBC Bay Area, Apr 11, 2017: A pathogen that eventually caused brain lesions is the reason why a shark became stranded on a Santa Cruz beach and later died last weekend. Animal experts say the pathogen is unlike any kind of bacteria that has been seen in sharks before.
KSBW transcript, Apr 11, 2017: “They say it could be the same infection that’s killing mako sharks this year… but the question remains, why is the infection making its way through different shark species?” - Sean Van Sommeran, Pelagic Shark Research Foundation executive director: “Let’s see if we can exactly identify what appears to be a new type of brain infection - first of its kind, documented in a white shark like that.”
KSBW, Apr 11, 2017: Van Sommeran said the pathogen is unlike any kind of bacteria that has been noted in sharks before. “Necropsy results show severe necrotic brain lesions”
God save online comments to internet news
Opportunities for an existing pathogen? - The die-off appeared to be centered on the shoreline around Foster City. Stranding reports came from nearly every part of the Bay, however, and involved several fish species. In an email update from the California Department of Fish and Wildlife on July 21, Okihiro estimated the die-off has claimed more than 1,000 leopard sharks, 200-500 bat rays, hundreds of striped bass, and nearly 50 smooth-hound sharks, as well as small numbers of thornback rays, guitarfish, and halibut.
Not just sharks.
But, I thought it was a fungus.
Okihiro originally thought the cause might be a fungal pathogen that he found growing on Petri dishes cultured from the brain and inner ear fluid of the first three leopard sharks he examined. By early May, after examining a handful of sharks he’d gathered while walking the beach south of the San Mateo Bridge, Okihiro thought he was closing in on a fungal killer.
So, same limited dataset gives same limited results?
Finally he sent samples of cerebrospinal fluid to the UCSF lab of Joseph DeRisi, an expert in the genetics of infectious disease. Hanna Retallack, a graduate student in DeRisi’s lab, used techniques called polymerase chain reaction (or PCR) and metagenomic next generation sequencing (or mNGS) to look for genetic evidence of Miamiensis avidus infection. She found the protozoan’s DNA in 14 sharks, and its RNA signature in five more samples. Okihiro now says he’s “90-100 percent confident” the protozoan pathogen is the primary cause of the strandings.
Weakened by hunger and poison, all the creatures will succumb slowly to existing opportunists in nature …
Or, nature will respond to the environmental change and create something new. More adapted. More virulent. Dominant to the conditions.
Cascading waves of change.…
Reminder from deja:
The chapter abstract on Microbial Biota documents that radionuclides mutate viruses and bacteria to form new and mysterious diseases.

It's raining, still here posting. "Mother sharks transfer radioactive contaminants to their young." (what about humans?)
[i] Because Bluefin tuna are harvested annually in the Eastern Pacific Ocean (EPO) for human consumption (2000 to 2010), the possibility of radioactive contamination raises public health concerns.
All 15 PBFT collected in 2011 contained 134Cs (4.0 ± 1.4 Bq kg−1 dry wt) and 137Cs (6.3 ±1.5 Bq kg−1) in white muscle tissue. At the time of capture, total 134+137Cs concentrations were about 10 times higher in 2011 PBFT than in PBFT from previous years.
Back-calculated 134Cs:137Cs ratios suggests that the radiocesium levels in California-caught PBFT were the result of <1 mth exposure to contaminated waters near Japan.
Other highly migratory species (HMS) (e.g., turtles, sharks, and seabirds) that forage near Japan may assimilate radiocesium and transport it to distant regions of the north and south Pacific.
