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 is an excellent short article on the challenges of treating for parasites, and why sometimes, alternative methods are more effective than increasing the doses of chemical to kill the parasites.  While this article is about farmed fish - salmon - the parallels to Koi keeping are obvious, and the lessons to be learned may help us in more effective parasite treatment for Koi.  Note that Koi suffer from lice also - albeit a slightly different species...

Murray-Darling carp herpes deemed safe for swimmers, but locals fear 'toxic swirl."

European carp infected with a strain of herpes will not pass the virus — or any other diseases — on to water users who come into contact with them.

This article is by Syd Mitchell - K.O.I.'s Water Quality Instructor - often nominated for Sainthood by his students...  Syd discusses chemicals used to treat a wide variety of problems...

This article is by Syd Mitchell, our Water Quality instructor extraordinaire!  In this article, Syd discusses various techniques that work with different predators.

Everyone is always asking me to post articles on Koi judging.  For many Koi keepers, being able to produce show quality Koi and get recognized for doing so is the epitomy of the hobby.  Many others prefer to just enjoy their Koi at home, but all of us are affected by the Koi judging considerations, because they are the same considerations that dealers use to put a value on the Koi we buy.  So - we need to understand as much as we can bout how Koi are valued.  I have omitted parts of this article that are unique to the UK, but what is included should be of interest to all!

If you are all tracking the story, the Australia government is about to release KHV as an agent to destroy unwanted wild carp in the Murry-Darling basin in Australia.  Below is a copy of the actual Phase 3 Final report for the KHV project and comments, all of which were posted on the PetSmart web site.

I wanted to find a gift for a Koi buddy - and you know how it is - they have EVERYTHING related to Koi!  I found these great little salt and pepper shakers, and they are both beautiful and practical!  The person just loved them and uses them every day - and suggested I tell everyone!  Just look at the others I found - all on Ebay - search for "Koi Salt Pepper."

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.

Fish are masters of reproductive resilience.

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.
