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!

Koi judging in Japan is based on the 50-30-20 rule and includes the three basic topics, including 50% conformation, 30% quality, and 20% pattern, followed by standards within each variety.

When purchasing Koi for show you may want to base your choice on these topics as this is how shows are judged. Those purchasing Koi for pleasure will also find satisfaction using these topics as a guide in the selection of pleasing and healthy Koi.  

Conformation is the appropriate body shape, proportions, finnage, head shape, spacing and can include the ability to emanate power.

While Carp Edema Virus (CEV) was originally limited to Japan, it's now out there in Europe, and probably the USA too.  If you keep Koi, you'll need to learn more about this killer Virus...  Remember, there is NO CURE for viruses, the only way to keep your Koi alive is to PREVENT it in the first place.  Read the abstract below, and I've also posted a link so you can download the original research.

Tag, you're it, the chase is on! It's early summer and love is in the air, in our ponds that is. It's a beautiful, sunshine day, and then it hits you - foam everywhere; phew, that fishy smell; plants shredded and tipped over. The girls are round and robust and the boys are egg-seeking missiles hot after the girls making laps chasing the girls around the pond. What is all this "kommotion?" The water temperatures and day lengths are ideal and it's time for spawning.

The very first bony fish on Earth was susceptible to arthritis, according to a USC-led discovery that may fast-track therapeutic research in preventing or easing the nation's most common cause of disability.

Ancient southern China fish may have evolved prior to the 'Age of Fish.'  'Shield scale' fish may provide insight into the early evolution of jawed vertebrates.

The word 'fish' is a convenient way to refer to a variety of diverse aquatic creatures, some of which are not, strictly speaking, fish. 

I'm asked all the time about how to make paper-folded Koi - Here is another tutorial.

Do you know what fins, barrels, epidermis, and gills are and what their functions are? Do you know that the cuticle layer is considered the first layer of defense against disease and parasites?

A Koi owner in CT recently had to give up the hobby because otters would kill any Koi he put in his ponds.  The following story is about a Koi owner in England who was finally able to defeat the otter the was killing his Koi and goldfish.  Certainly straight-sided, deep ponds deter herons, but not otters!

Did you know that if you are a K.O.I. member, you have access to one of the BEST Koi magazines ever produced?  Koi Health Quarterly was written by the Koi Health Group (a group of veterinarians concerned about Koi Health) from 1993 to 1997.  There are 16 amazing issues, each packed with specific information about Koi for the hobbyist Koi keeper.  This article in Iisue 9 is way ahead of it's time.  We recently reported on a book published in 2016 and concluded that fish do feel pain, but this little article was published over 20 years earlier! 

Red Koi, blue Koi, upstream, downstream, what are Koi meanings in tattoos?
