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!

No less than 500 new species of cichlids, brightly coloured perch-like fish, evolved in Lake Victoria (East Africa) over the past 15,000 years -- a record in the animal and plant world. This evolutionary puzzle has now been solved by scientists from Eawag and Bern University. In a study published in Nature Communications, they demonstrate for the first time that this rapid evolution was facilitated by earlier hybridization between two distantly related cichlid species from the Upper Nile and Congo drainage systems.  Read more by clicking on the title or picture.

While most salts and chems are BAD for Koi ponds, some new chem are now available.  These still may be undesirable for Koi ponds, but they are apparently somewhat beneficial for lakes.  Organic additives found in road salt alternatives -- such as those used in the commercial products GeoMelt and Magic Salt -- act as a fertilizer to aquatic ecosystems, promoting the growth of algae and organisms that eat algae, according to new research published in the Journal of Applied Ecology.

We know many Koi keepers either started with or also keep Aquariums, and we also know that many Aquarium keepers also have Koi ponds - once you know how to keep good water, both hobbies are fun!  Here's an interesting article on the trends of the Aquarium hobby in 2017, just for those of you who are interested!  Read the article by clicking on the title or picture.

The Center For Invasive Species Program (CISP), a private, non-government organization, has brought a petition the US Fish & Wildlife Service to include within the Lacy Act 43 aquatic animals as “injurious species”.  Thirty-one (31) on the list are fish.  Some of which are very popular in our hobby and if this is adopted, it would become a felony to transport live fish such as Koi and guppies to fish shows across state lines.  In addition, these fish could no longer be imported into the United States nor could you purchase these fish from outside your home state.  See the list and contact info by clicking on the picture or title:

New research published in May of last year shows that other species can be asymptomatic carriers of KHV, but they have not proven that they can transfer the virus to naive Koi.  Read more by clicking on the title or picture.
