Hello Koi Enthusiasts!

This blog is here to provide a spot for various things that do or might pertain to Koi. This stuff is intended for your entertainment, and is not meant to meet the stricter standards of our ebooks and courses, so use this info carefully and at your own risk. The short articles here may be descriptions of techniques that have proved effective, an introduction to new fish research, facts, graphs or just something FUN about fish! This information can be a springboard for your imagination and an entertaining place to learn something new. Information that was first published in Question of the Week can be found here.

The more we learn about Koi, the more FUN this hobby is - and we always say - if you're not havin' FUN, you're not doin' it right!

I wonder when we will see nuts in our koi feed?
Thanks to researchers at the Agricultural Research Service, a new feed ingredient made from tree nuts is available to fish farmers.
As the aquaculture (fish or shellfish farming) industry grows, so does the need for fish feed that's not dependent on the stagnant supply of fish meal made from captured marine fish protein and oils.

Another story on the research about fish and their amazing intellect. 

... It came as a surprise to learn that studies suggest that just as I enjoy peering into their underwater world, the fish are enjoying their view of my living room as well. What must my fish be thinking as they watch my family members sitting on the couch, moving about searching for lost keys or stealing a cookie? Reports from experimental lab studies give insights into what fish are able to detect in their surroundings and how our interactions with our pet fish might need a second look. 

Most people think of fish as somehow lesser than pigs, cows, chickens and other land animals.

Keepers at Sea Life Brighton Brighton have said Queen Gary III enjoys looking at the movement and bright colours as the queens sashay down the runway.

We all worry about our fish suffering, so Henry Kim created a goldfish 'wheelchair"

In a fairy-tale transformation engineered by man, the dull, grey carp was bred to a metallic sheen more than a millennium ago.
"Oh, wet pet," American poet Ogden Nash wrote in pithy summation of the humble goldfish, whose habitat is, by tradition, a glass bowl anchored by the faux luxury of a gravel-bound ceramic castle. But the reality is more complex, suggests a new book by Anna Marie Roos, a professor of the history of science and medicine at the University of Lincoln.

PSYCHOLOGIST Richard Wiseman’s taste for quirky science is well known, so his pet personality project should come as no surprise. In an online survey, he asked people to rate their pets for things like friendliness and neuroticism. Over half of fish owners said their watery friends had a good sense of humour. Fish apparently appreciate a joke more than cats, horses and birds – but not as much as dogs. Reptiles entirely fail to see the funny side of things, according to their owners.

Simply amazing; check out both the story and a collection of his work.  

According to this story our Koi get drunk in the winter!
During the winter, goldfish and their relatives can have a blood-alcohol concentration beyond the legal limit for drink driving.
Scientists have figured out how goldfish produce alcohol to survive when trapped beneath the icy surfaces of frozen lakes and ponds.Unlike most vertebrates which die within a few minutes without oxygen, goldfish and their wild relatives crucian carp are able to survive for months in low oxygen water.

Our fish just might be lonely and sad without us!
Fish at a popular aquarium in Australia have begun to show signs of depression after the facility was closed to the public in mid-March due to the COVID-19 pandemic.

Churchill's last work in oil
Winston Churchill turned to painting around 1914 but by 1962 he had all but stopped. Churchill's bodyguard Edmund Murray encouraged the aging statesman to take up his paintbrushes one last time. As a subject, Churchill chose his estates goldfish pond, where he spent Sundays with his grandkids. He gifted the work to Murray. "The Goldfish Pond at Chartwell" earned 357,000 GBP at a Sotheby's auction.

A fish tale we can understand:

An animal lover has struck up an unlikely five year friendship with a fish after they ‘locked eyes’ in a lake. Holly Jorgensen has become such good pals with the sunfish, named Greenie, that he now waits for her to appear and lets her rub its chin.

Your koi and the circle of life - oh my:
Natural selection doesn’t favor brightly colored fish with predators like ospreys around,” I was told by Jim Levitt, a fisheries biologist with the fisheries division of the Minnesota Department of Natural Resources.

Looking for away to bring water plants indoor?

Australians are obsessed with indoor plants – a recent report from the Nursery and Garden Industry of Australia revealed that plant sales from retail nurseries totalled over $1.3 billion in 2018 – but not all of us are great at caring for them or keeping them alive. A separate survey by Plant Life Balance, found that Australians have managed to kill at least 72 million plants in the past year.

Heron problem: train a crow!
A homeowner has been paying a crow in mealworms for chasing a hungry heron out of his garden after it stole hundreds of pounds worth of fish from his pond. 
Simon McCabe, 51, says the heron has 'emptied' the pond in his back garden of koi carp and goldfish.
But ever since the crow started visiting the garden last month, the little bird has 'looked after' his pond community and he's not lost a fish since.

A wonderful story about Copperbelt University and the students hopes this fish inspired. 
Zambia's President Edgar Lungu has joined the nation in mourning the death of a fish that lived in a pond at the country's second-biggest university.

Students at Copperbelt University (CBU) lit candles and marched around campus to mourn the big fish.The hashtag Mafishi, as the fish was affectionately known, is trending on Twitter in the southern African state. 


A bear hilariously faced off against a team of plastic ducks after dipping into a newly-built koi pond for a quick swim.
Footage captured in Jim Thorpe, Pennsylvania, shows a large bear wander over to the pond before slowly submerging into the water to cool off from the heat.
The pond's owner, who filmed the footage, is heard telling the bear to 'get out of there!'

This Black Headed Cardinal is actually feeding these fish. Check out this Youtube.
