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!
In late 2016, the Australian Government commissioned a two-year research and planning process to determine the feasibility of using a virus (known as Cyprinid herpesvirus 3 or CyHV-3) to control invasive European carp (Cyprinus carpio) in Australia [1,2].
This is an excellent article written by 3 vets (Roberts, Palmeiro and Weber) that covers:
Stress has all sorts of consequences for fish, some of which we are just beginning to understand.
If you are one of the millions of proud owners of freshwater angelfish, you might be surprised to find out how simple it can be to calm the often feisty fish: Change their water less often.
If they weren't in the windowless basement of a cavernous biomedical research building, the "Aquatic Suites" might sound like a cushy vacation destination.
The evolution of land animals only happened once, some 400 million years ago. But what pressures pushed sea creatures to evolve limbs for walking? Scientists have proposed several theories, including fish that adapted to living in shallow, plant-choked streams prone to flooding and drought. Now, new research suggests that that strong ocean tides may have played a significant role, stranding animals in tidal pools and giving them an incentive to escape back to the sea.
If you’ve ever visited an aquarium, you might have noticed tiny “sparks” of light dancing around the eyes of some fishes.
For you paper-folding enjoyment, we have 2 more Koi Origami patterns for you, this time, a bit more advanced!
Those questions and more are answered in this video by Fish Vet Richmond Loh in Australia… Definitely worth watching!
20 minute webinar recording on "KHV for Koi Owners" by Dr. Jesse Sanders on YouTube. Covers "What is KHV, How is it transmitted, Symptoms, and Testing."
The most likely problem to arise from introducing herpesvirus to carp populations in Australian waterways is one of effectiveness, according to an international team of researchers including Griffith University Adjunct Research Fellow Dr Jonathan Marshall.

A seminar in the Jan/Feb 2018 Aquatic Symposium, held in Sydney Australia, has session a session on Fish Sentience, Cognition and Behavior, by Professor Culum Brown, department of Biological Sciences, MacQuarie University.
There are many times when we would all like a tripod to display something - pond pics, charts, a white board, etc... Here are Spike Cover's directions (including pics!) to build a FAST, nice, inexpensive tripod - or a bunch of them! And you can collapse it for easy storage too!
Belgian, English and Australian scientists are calling on the Australian authorities to review their decision to introduce the carp herpes virus as a way to combat the common carp having colonised the country's rivers.
As a shark biologist, I enjoy nothing more than going scuba diving with sharks in the wild. However, I realise it’s an immense privilege to do this as part of my work – and that for the vast majority of people experiencing the underwater world in such a way is simply not possible.
Your smartphone could soon be a fully functional microscope capable of examining samples as small as 1/200th of a millimeter.

Tap water contains chlorine, a disinfectant that makes water safe for humans, but is harmful to fish. It is removed with a purifier, a dechlorinator, or a water treatment product from an aquatic outlet.

Water from a household tap, a borehole or well, or rainfall will have unique properties and individual chemistry influenced by the location.
A Canadian woodworker was inspired by the strength and perseverance of Koi to create the piece in the picture above.
Our K.O.I. courses help you be prepared for problems, but a 2nd backup component is called for when a mechanical failure can cause Koi deaths. So - never use one air pump - use 2, and perhaps even more importantly - wire them to different circuits! Fish researchers at the University of Alberta, Canada had 2 pumps - but they were wired to the same circuit, and mechanical failure caused over 9000 fish deaths, including a Koi collection. At the University, the device that caused the deaths was a de-chlorination pump - but for most Koi keepers, it's the air pump that's the critical component.

Koinobori, known as carp wind socks, streamers, or banners, are seen across Japan's countryside from April to early May. Most importantly, they are the traditional decoration on May 5th, which is Children's Day.

How long can you hold your breath? That's what you are asking your Koi to do...
