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!

This site has several amazing photographs of koi by Jesse Rockwell as she discover a "secret subterranean aquarium. 
 

If you are into gaming, or have friends or family who game, you will want the Xbox game Grounded.  It has a koi pond of which ant sized players need to explore and defend!
 
Grounded is a first and third-person cooperative survival game by Obsidian Entertainment and Xbox Game Studios. It was first revealed at X019 in London and entered early access on July 28th, 2020.

If you are looking for an A-Z list of diseases of koi, this presentation in 1998 by Nicholas Saint-Erne, DMV is amazing.

In a recent study, an international team of researchers analyzed fish bones excavated from the Early Neolithic Jiahu site in Henan Province, China. By comparing the body-length distributions and species-composition ratios of the bones with findings from East Asian sites with present aquaculture, the researchers provide evidence of managed carp aquaculture at Jiahu dating back to 6200-5700 BC.

An interesting story of tossed out goldfish in a lake and its consequences. 
 
The most likely culprit behind the invasive species? Pet owners who illegally dumped goldfish, officials say.

I am slipping this article on my husband's desk. I need a Hori Hori knife!
 
The tool kit of Japanese master gardeners is the object of envy. Luckily for amateurs, beautifully made and durable Japanese garden tools are within easy reach. Here’s a collection of our favorites.

Apparently the author has never been to a koi show!
 
A city in China has been crowning the Miss Universe of the goldfish for the past four years.

Do we need a cappuccino whisk as part of our first aid kits for our Koi?
 
‘It was in the water and it was a warm day and obviously the oxygen had dropped very low and the fish was suddenly floating on the surface,’ Phillip recalled.

Common carp were part of this study that looked at the dynamics of scales and drag for airlines.  Scale design may provide significant saving in fuel for planes. 
 
The team's findings have been published in Nature: Scientific Reports: "Transition delay using biomimetic fish scale arrays," and in the Journal of Experimental Biology: "Streak formation in flow over biomimetic fish scale arrays."
Reducing drag means faster aircraft speeds and less fuel consumption—an important area of study for aerodynamicists...
 

Another story on fishless fish food. 
 
After six years of research, a team of scientists at the University of California, Santa Cruz has developed a cost-effective new aquaculture feed that eliminates conventional fish meal and fish oil ingredients while also providing better fish weight gain and higher nutritional value in the filet for humans. The new fish-free feed is the first to demonstrate across-the-board gains in sustainability, performance, economic viability, and human health.
 

Insects are now in dog food, is it in your koi food now?
This past Tuesday (June 11), Dutch company Protix opened the world’s largest insect farm in Bergem op Zoom, a small town in the south of the Netherlands.

Fish fins aren’t just for swimming. They’re feelers, too. The fins of round gobies can detect textures with a sensitivity similar to that of the pads on monkeys’ fingers, researchers report November 3 in the Journal of Experimental Biology.

A new trend of replacing fish in fish feed, to substituting insects. 
 
French insect farming startup insect is building the world’s largest insect farm in Amiens, north of Paris. Set to open in fall 2022, per TechCrunch, the facility will focus on raising mealworm beetles — specifically their larvae— for commercial uses, including fertilizer and as food for pets and aquaculture.

Dame Judi Dench, a fish and pet lover!  Wonderful story with a happy ending. (picture credit: Judi Dench| CREDIT: ANDREAS RENTZ/GETTY)
 
“I gave it the kiss of life. It died when it was a very, very little goldfish,” she added [Judi Dench], noting that fortunately not only did the fish end up surviving, but that it also grew to be “about six inches long.”

An important article on Australian invasive carp and plans to kill by KHV.
 
International researchers and local experts describe the federal government's plan to release Kopi Herpesvirus into the Murray-Darling Basin as "madness", saying the science is still out on its safety and effectiveness.
Researchers say plans to release a virus to reduce numbers of invasive Common Carp in Australian waterways should be abandoned. 

Very, very interesting. included is Ted Talk by the article's author.
 
Every day, corporations like Facebook, Amazon and Google learn more and more about human behavior by collecting incredible volumes of data — what’s called Big Data — on our social behavior. They use it to learn things like how our behavior is influenced by the behavior of other individuals in our social network.
But what if we could do the same thing with animals in nature?

This beautiful koi named Dragon Gate, has survived two attacks by otters and has the scars to prove it.  Thanks to Bloedel Conservatory, Dragon Gate is safe in its new home. 
 
Vancouver’s oldest koi, which survived a pair of otter onslaughts at the Sun Yat-Sen Chinese Garden has been moved and is adapting “swimmingly” to his newly-renovated home.

Ahh fish, amazing partners in the Mangrove exosystems!
 
...according to a new study by the University of Michigan, two tropical fish may be mangrove’s ‘most valuable players’ in the pursuit of nutrients - by providing the mangroves with their nutrient-rich urine.

Many thanks to Michael Landesman, a K.O.I. student, for sharing his construction video with us. 
This video is masterful at showing the process of pond construction. No words, just great video/music that shares a well documented process to the family's new pond. 
 

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.
