Upgrading your filter? What must you do to prevent fish deaths?

Many people forget about the nitrogen cycle when they have been keeping fish for some time. It can catch people unaware.

Quite often, people might upgrade their filters. Either by changing the filter material with something with more surface area (e.g. from filter sponge to ceramics), or by replacing the entire unit with a larger or more powerful one. This can put your fish at risk. Why?

The new filter will be devoid of the beneficial bacteria that converts your fish wastes to safer substances. You will be in danger of “new tank syndrome” whereby you can get dangerous levels of ammonia or nitrite that can kill fish. Why is this?

The majority of nitrifying bacteria do not live in the water column. They pretty much only colonise the surfaces of objects. This means the surfaces of the glass, plants, gravel, rocks, furnishings, etc. It is the filter that harbours the greatest number of these good bacteria because the filter material is socially designed to have a large surface area. So, by removing the old filter or filter material, you’re effective getting rid of your good bacterial population.

So how do you avoid such a situation? The best thing to do is to seed your new filter with old filter media, or run both filters at the same time, while the bacteria has a chance to establish themselves in your new filter. This might take up to 4 weeks in freshwater tanks, and up to 6-8 weeks in marines.

There’s something fishy going on at the Denver AVMA Convention.

In just a couple of weeks, a group of fish vets from around the world will be convening at the AVMA Convention to give presentations and to run a ‘wet’ workshop.

If you’ve not already done so, make sure you’ve signed up for these. I’d love to see you there.

Are you eating “Fukushima Radiation and Bloody, Cancerous Tumors in Fish Contaminated By Radiation”?

This revision now includes my statement and evidence on the mistruths of the article.

 

To explain, at the time (2014), I didn’t have enough information to decide whether it was a hoax, or whether it was true in parts. As such, it was published on my blog to see what others had to say. Some 3 years later, a reader from (would you believe it) Richmond (not me!) has prompted me to review this blogged article… and rightly so.

 

Well, if you’re ever unsure about material circulating around the internet, Snopes.com do some good fact-checking. The mentioned article appears to be all patched together, from unrelated content, to produce this hoax:

 

Our reader had also gone to the trouble of finding the original sources of some of the pictures that have been used inappropriately in the article:

It also appears that Turner Radio Network is illegitimate, and the Google link to it, brings you to a worrisome site. And Wikipedia even has a page dedicated to “Hal Turner“.

 

Our reader also provided a link to the work that has been performed through DEC regarding testing of fish samples for radiation – http://dec.alaska.gov/eh/Radiation/index.html

 

So, without further ado, pasted below is the mentioned article; and you can now tell everyone that this is a hoax:

 

 

SURPRISE: You’re Eating Fukushima Radiation and Bloody, Cancerous Tumors in Fish Contaminated By Radiation TurnerRadioNetwork Tuesday, 28 January 2014

1

Americans and Canadians have been eating radioactive fish filled with bloody, cancerous tumors as a result of fish being contaminated with huge amounts of radiation in the Pacific ocean from the Fukushima nuclear disaster in Japan.  

In March, 2011 an earthquake off the coast of Japan caused a Tsunami which hit the Fukushima Nuclear Power Plant, causing three reactors to melt down.  Not only has that disaster site been spewing 400 tons of highly radioactive water into the Pacific Ocean every single day since the earthquake, the radiation has reached the US West Coast and the fish you’ve been eating from the Pacific ocean are full of it!  The radiation in the fish is so terrible that wild-caught Alaskan Salmon and Canadian white fish are being found to have bloody, cancerous, tumors throughout their bodies.  

The government and the nuclear power industry claim we have nothing to worry about.  When you see the photos below, you may want decide for yourself if they’re telling the truth.  

According to the Local Environmental Observers (LEO) Network in Hydaburg, Alaska, they have found strange growths in the flesh or meat of salmon. “We were fishing for cohos (silver salmon) at the mouth of the Hydaburg River with line and reel.” said Brian Holter, Jr. who said that eight fish  were filled up inside with strange growths that were either white or pink in color. “On the outside the fish looked fine. The growths looked kind of like individual little salmon eggs, and about the same size. Other people were seeing the same kind of growths in their fish as well.” he continued.  

This is what the tumors inside three separate Salmon looked like:

The map below will give readers an understanding of the proximity of Hydaburg, Alaska to the Fukushima, Japan disaster site to demonstrate how far the effects of Fukushima radiation have traveled in the three years since the disaster began:

FAR NORTHERN ALASKA IMPACTED TOO Other volunteers from LEO have come across even more disturbing cancerous tumors and bloody lesions on fish. According to another LEO volunteer, Sam Kunaknana, in Nuiqsut, Alaska, for the past few months they have been catching sick fish on Nigliq Channel and upstream from Nigliq Channel to the Colville River.  The fish have had bloody lesions and tumors on them.

Sadly, the images above aren’t nearly the worst of it.  Other fishermen and even Marine Biologists have caught other fish showing classic signs of radiation-caused cancerous tumors.    “In all the years I’ve been fishing I never caught any fish like this. Caught 3 more sick fish with same markings and this time one had some kind of growths coming out from its mouth  Most people in our community eat this fish.” Sam Kunaknana continued.

While there is no way to tell exactly where in the Pacific Ocean these fish have been, one thing is for certain: they’re ALL from the Pacific Ocean.  Yet numerous “scientists” have repeatedly stated that “dilution is the solution” for the Fukushima pollution.  These “scientists” say the Pacific Ocean is so big and has so much water, the radiation spewing from Fukushima can’t possibly be bad enough to affect humans. The pictures  in this story seem to prove those “scientists” wrong.  

Certainly, the Pacific Ocean is huge.  Yet as the map above shows, distance from Fukushima did not seem to matter with the fish caught near Hydaburg, Alaska.  

The map below, shows the location of the other LEO volunteer, Sam Kunaknana, in Nuiqsut, Alaska, thousands of miles farther away from Fukushima than Hyanburg. In fact, Nuiqsut, Alaska is about as far north as one can get from Fukushima, but the radiation has gotten there too.

FISH IN CANADA ALSO AFFECTED If the strange lesions and cancerous tumors were only affecting Salmon, one might theorize that a particular disease had struck a particular species.  That’s not the case. As shown below, Alberta Pike are also being caught with grotesque cancerous tumors protruding outside their bodies.

Tumors are also affecting other species of fish like the Canadian Whitefish shown below:

Vancouver Island Area Herring are also being found to be bleeding from their gills, eyes, mouths and bellies.

HISTORIC FIRST: GREAT WHITE SHARK WITH CANCEROUS TUMOR! We’ve all heard for years that sharks don’t get cancer.  Well, when they swim around the Pacific Ocean nowadays, the radiation is so terrible that even sharks are getting cancer. Recently, researchers in Australia noticed a large tumor protruding from the mouth of a great white shark, as well as another mass on the head of a bronze whaler shark. The great white’s tumor measured 1 foot (30 centimeters) long and 1 foot wide, according to a study describing the tumors published online in November in the Journal of Fish Diseases. “This was a very unusual sight as we have never before seen a white shark with tumors,” said Rachel Robbins, a study co-author and shark biologist at the Fox Shark Research Foundation, near Adelaide, in southern Australia.   Behold, the first photo in the history of human existence, showing a Great White Shark with a cancerous tumor on its mouth:

NOT JUST FISH BEING AFFECTED As stated earlier, some have said that there are explanations other than radiation for these ailments.  Certainly that might be worthy of consideration.  Yet, how many of these so called “ailments” can cross-species?  You see, it is not just fish being affected; mammals are too.  

Below are images of various types of Seals, Walruses and even Polar Bears.  ALL of them are suffering bloody lesions, some are suffering external tumors and others are losing their fur – hair loss is one of the first signs of radiation poisoning, even in humans.  See for yourself:

Walruses: Polar Bear: Losing hair is one of the first signs of radiation poisoning.

U.S. GOVERNMENT HAS DONE — NOTHING The federal government of the United States of America has done absolutely NOTHING to test for radiation in the Pacific Ocean.  Nothing.  

Freedom of Information Act (FOIA) requests to the U.S. Fish and Wildlife Service confirm they “have not tested for radiation and have no plans to do so in the future.”  A FOIA request encompassing the entire Department of the Interior, via the Office of the Secretary, resulted in being told “The office of the Secretary does not have any records relating to your request.”  The Federal Aviation Administration FOIA response was “FAA is not involved.”  The FOIA response from the Nuclear Regulatory Agency was “NRC does not conduct the types of tests in your FOIA request.” The Federal Energy Regulatory Commission (FERC) replied “We do not conduct such tests.” The Environmental Protection Agency replied “Please understand that these reports take time to create. Report 154 is currently under review at our laboratory and will be published once the review is complete.”  (That report is over a year old and they still haven’t reviewed it yet???) The National Oceanographic and Atmospheric Administration (NOAA) replied they want $7098.84 to fill the request; their charges are as follows:

Action Officer Estimated number of hours Hourly Salary Benefits @16% Hourly Cost Total Cost
Senior Scientist 40 = 38 38 $74.47 $11.92 $86.39 $3,282.82
Senior Scientist 20 $81.10 $12.98 $94.08 $1,881.60
Senior Scientist 4 $81.03 $12.97 $94.00 $376.00
Senior Professional 2 $67.66 $10.83 $78.49 $156.98
Senior Professional 16 $75.51 $12.08 $87.59 $1,401.44
80 $7,098.84

So,  there you have it.  For three years, the Fukushima Nuclear Power Plant disaster has been spewing deadly radioactive material into the Pacific Ocean and for three years, the agencies above have done nothing.  Without admitting they have done nothing,  NOAA wants $7098.84 to merely LOOK to see if they have any records relating to a request!  

In the meantime, fish from the Pacific Ocean are contaminated with — and dying from — Fukushima radiation and that means the radiation is in the seafood that YOU, your family, maybe even your cats and dogs are eating.  

The next time you hear anyone from government say “we have no reason to believe there is any radiation hazard” bear in mind it is because they are not testing for it.  That’s why they have no information . . . . . and . . . .  conveniently . . . .  “no reason to believe” there is any danger.  If this situation wasn’t so pathetic, it would be laughable.  

You folks on the west coast of North America might want to consider your activities this coming summer.  Maybe if YOU go swimming in the same water these fish swam in, a couple years later YOU could come out looking like they look!  

As for everyone else, head-on-out to your local supermarket or restaurant and eat-up; the government says it’s safe and they _never_ lie!

How many arms does an octopus have? Only six – the other two are legs!

Marine experts found common octopuses moved over the ground using their back two limbs, leaving the remaining six for eating.

What causes my fish to be swollen/bloated?

“Bloated” look alone can sometimes be misleading. Some common conditions with a similar appearance include being egg-bound, fat, having a tumour/cancer inside the body cavity and systemic bacterial infection leading to dropsy (where fluid accumulates in the body and their scales start protruding). Some diagnostic procedures your fish veterinarian might use to tell these apart include X-ray, ultrasound, palpation and fine needle aspirate of the abdomen for cytology examination.

If it is indeed egg-bound, you can try using Epsom salts in the water. For koi in outdoor ponds, you can wait till the next warm season, or use heaters to elevate the water temperature (gradually) to 22-24 degrees Celsius and maintain it for a period of at least 20 days. This will stimulate her eggs to mature. It’ll also help to have males in the pond to help stimulate release of eggs. Otherwise, by 20 days, she can be manually stripped. There is a hormonal induction method (e.g. injecting Ovaprim), but there might be complications if she’s injected too early and the conditions aren’t right. This is why such medicines are only available through a trained veterinarian. If it is a tumour, it may be possible to perform surgery to remove it. If it is a bacterial infection, antibiotics may be a solution if it is not too late.

 

They want to do WHAT with fish? Alarm raised over import plan for Australian Doctor Fish pedicure business.

A BEAUTY chain has applied to the Federal Government to import an exotic Middle Eastern fish to nibble dead skin off clients’ feet.

The Environment Department is deciding whether doctor fish can be imported for fishy pedicures which have become a fad in the UK, US and parts of Asia.

There are concerns over the human safety aspects of spreading diseases between spa users, environmental threat by the foreign fish and welfare concerns for the treatment if fish.

Is there a book that explains the science of fish keeping?

In a conversation with a client,”[I] have been trying to read up about the water chemistry… can you recommend a book that explains the science properly? It’s hard to know what’s correct on the internet!”
 
Why, yes of course!
Check out this book!
