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 think my pond and koi could use a few more of this type of bacteria! A very interesting study, enjoy. 
 

This fish, that soon was know as Carrot, was put in this Fishery in France 20 years ago. 
 
The article states "The fish is a hybrid species of a leather carp and a koi carp, which are traditionally orange. It's believed to be the second largest of its type caught.
 
"The angler posed for a snap with his catch before releasing it safe and well back into the lake. He celebrated with a cup of tea afterwards.
 

Another loss of habitat for a branch of the carp family. This short article shares a bit about lost carp species and the people who depended on them for food. 
 
"Just two species of the freshwater fish still exist in the ancient waters of Lake Lanao in the Philippines after predatory fish were accidentally introduced
 

I absolutely love this big bear cooling down in this pond, until....... Enjoy this very short video and find someone to share it with. It will have you laughing. 
 
"This is a story of a black bear who got into a backyard fishpond to cool off from the summer heat until the resident koi carp scared it away.
The bear entered the pond in the Massachusetts town of Pepperell, panting heavily as it soaked its fur into the water and quenched its thirst as koi carp darted around it.

Wanting to add some flowering plants to your pond; here is a guide to help you. 
 

Okay, besides being a bit on the wacky side, I consider this animal abuse! However, apparently they take good care of their finned friends. 
 
"Two performers said that stunt is not for the faint-hearted"
"It is a fishy act that could take your breath away - or more likely that of its underwater performers.
Two “aquamen” amazed crowds gathered in Saint-Malo in Brittany by strolling around with fishbowls on their heads filled with water and goldfish. They breathe through a special valve."
 

Great work on memory of goldfish. We know our koi can do even better.  
 
"It’s long been a common belief that fish have the memory capacity of only a few seconds. People often make fun of people with bad short-term memory by saying they have the “memory of a goldfish.”
 

Yes, and we have all seen koi in cramped tanks, too small of ponds without adequate filtration and oxygen.  Another reason Koi Organization International (K.O.I.) exists.  
 
K.O.I. is an international group of expert hobbyist-volunteers who want to promote FUN in the Koi hobby by teaching all aspects of Koi and pond keeping, with a focus on Science. 
 
PARIS, Jan 22 (Reuters) - A leading French aquarium vendor has decided to stop selling round fish bowls because they drive fish mad and kill them quickly.

You don't need to read the entire article to find the tidbit about koi - it right below for you - but it is an interesting article. 
 

Now this is interesting; do our koi do the same? 
 
A team of researchers at the University of Oxford has found via experimentation that goldfish use markings on the floor below them to measure how far they have traveled. The findings are published in Proceedings of the Royal Society B.

Okay, for you koi fanatics, this man certainly loves his koi and jumps right in.  Enjoy this short video!

Koi seem to have their own way of swimming as studied and described in this research by Wu, Yang and Zeng.  If you are into kinematics and hydrodynamics this is the reseach paper for you.
 

This reseach gives "frozen fish" a whole new meaning.  My wonder is if the Crucian Carp's cousin the koi is able to revive the same? For those loving a scientific article, you will love this. 
 
Crucian carp (Carassius carassius) survive without oxygen for several months, but it is unknown whether they are able to protect themselves from cell death normally caused by the absence, and particularly return, of oxygen....
 

This young man is not only a brilliant scientist with an amazing future ahead of him, but we at Koi Organization International (K.O.I.) are proud to call him one of our own. Indeever congratulations on your significant contribution to fish science and adding the knowledge of the genome of angelfish.  But we also appreciate that you are a Certified Koi Keeper (CKK) with Koi Organization International. We at K.O.I. look forward to continuing to highlight your future scientific work. 
 

Wow, I never knew.  This is a great article, and for the more science minded, read the entire research paper.  Both article and research links provided below. 
 
"Every winter, the northern European crucian carp gets frozen into the ice, and receives no oxygen. Every spring, when the ice melts, a seeming miracle occurs: the fish emerges from the ice and resumes normal life....

 

Are you being careful enough about keeping your beautiful water plants, and aquatic life from spreading into your local waterways!  In the local river in my community countless hours and $$$ are spent in ridding our river of plants and animals that should never have been introduced to our river and now cause problems for native life and the health of the river.  Though this article comes from Michigan State University Extension, its message is for everyone who keeps a water garden with plants and aquatic life.  Let's keep them in our ponds and not let them escape to ruin our local water

Raising koi is an industry that is growing across the world; a growing international trade bringing income to many in a variety of countries. Here is a study from Java, in southeast Asia, that looks at the results of current techniques used to grow koi in Java. Even down to keeping the snakes and frogs out of the ponds. 
 
 

This is a historical view of the domestication of fish.  Tilapia and carp are the first know domesticated fish dating back to 1500 B.C. Section 2.1 deals directly with the domestication of the carp.  
 

Even if you don't like research on koi, you will love this short, but very heartwarming research proving what every koi hobbyist has always known; we do build relationships with our beloved koi. Now proven through a scientific structured study, koi have personalities and indeed seek out voluntary relationships with their keepers. Though scientists have focused for centuries on the relationships between humans and mammals (especially captive mammals) this is likely the first fully scientific study in our hobby on relationship building between humans and koi.  Enjoy. 
 

A wonderful and short history of the humble goldfish presented by National Geographic. 
 
"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, in England.
 

Okay, time for a few laughs.  Koi jokes are just a click away. Here's an example:
 

Just hurt my wrists digging a hole between two koi ponds. I think it's carpal tunnel.
 

What do you call a fake fish? a de"koi"       >!(if you don't get it, say it out loud)!<

Is it time for your koi tattoo? 
 
Koi is a fish in Japanese legends and it is believed that if it succeeds in climbing the falls on the Yellow river at Dragon Gate then it would change into a dragon. Thus, the koi fish started getting lot of recognition and it started being revered as the symbol of advancement and worldly aspiration.
