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!

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...

One of the 13 best events to visit in the Fodor's Guide features Koi!

I am often asked the proper genus and species for goldfish and Koi.

Some of you know that I've been looking to buy a new motorhome.  While I'm looking for a Class A unit, I found this Fishy-Looking Trailer in my search!  What a cool camper!  It's not for sale - the people who built it just love it!

Nissan Xmotion SUV concept  car, recently shown at the Detroit auto show, is like a Japanese landscape, complete with Koi!

Fish sense water motion the same way humans sense sound, according to new research out of Case Western Reserve University School of Medicine.  Researchers discovered a gene also found in humans helps zebrafish convert water motion into electrical impulses that are sent to the brain for perception. The shared gene allows zebrafish to sense water flow direction, and it also helps cells inside the human ear sense a range of sounds.

Fish have special adaptations that leave us breathless in their complexity.  Read about tuna and their amazing fins...

For months fish that live in dark caves in Mexico go without food. They have gone far longer—millennia—without light, evolving to lose their eyes and skin pigments.

Now researchers have discovered these strange creatures have another oddity. To survive their food-scarce environment, the fish have evolved extreme ways of turning nutrients into energy.

In the past few years, research has shown that fish feel pain.  The question of whether or not fish suffer was the subject of a recent conference...

They're among the most amazing events of the wild world:

Africa's thundering herds of wildebeest.
The incredible migrating monarch butterflies.
The captivating chorus of the Gulf corvina. Wait, haven't heard of that last one?

When examining data on a graph or reading facts and figures from a newspaper, it’s important you understand the difference between percent and percentage point.

Begin the process of identifying unknown bacteria by observing their physical characteristics, such as cell wall, shape and linkages.

More than three-quarters of the earth's atmosphere consists of nitrogen, yet only four-hundredths of one percent of the mass of the oceans, atmosphere, and earth's crust is composed of nitrogen.

Koi whiskers are known as maxillary barbels.

Read this fascinating article about the new research...  There are definite implications here for Koi growth rates...

Koi can be hermaphrodites in addition to being just male or female.  Apparently, many fish have also evolved to be able to change sex.  If you're interested in the science, read the fascinating new research on how fish change sex - link to download the article below.

While none of these articles are specifically about Koi, the Koi keeper can learn many things by skimming these pages provided by Universities and the Aquaculture Industry.  All pdfs are available for reading on-line or downloading.
