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.

If you've missed the previous posts, then you may not know that the Ausies are planning to release KHV in the Murry-Darling basin in Australia to control unwanted carp.  Here is another excellent article that voices serious concerns over the government controlled planned release of KHV...

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:

The international scientific community does not support the release of KHV in Australia to control common carp.  Read this article that details the reasons, including excellent references by clicking on the title or picture.

All Koi Keepers should know something about Biosecurity!  It's so important, that K.O.I. offers a special course in it, where you'll not just learn the basics of quarantine and disinfecting equipment, but we'll teach you exactly what you use and how to do it!  Learn more about our course #208 - Biosecurity, Quarantine and Record Keeping - CLICK HERE.  And read a few key points from fish vet Dr. Loh by clicking on the title or picture...

Two decades ago, someone dropped a handful of unwanted pet goldfish into a creek in southwestern Australia. Those goldfish grew, swam downstream, mucked up waters wherever they went and spawned like mad. Before long, they took over the whole river.

Rather than euthanize an unwanted Koi or goldfish, or even finding a friend to give it to, some Koi and goldfish owners will release unwanted fish into the wild, and hope that they will have a good life... This is HORRIBLE for lots of reasons!  Please share this article with your club and anyone you know that keeps Koi or goldfish!  While this article was written in Australia, it applies EVERYWHERE!  Read the article by clicking on the picture or title...

In the ongoing saga of trying to control invasive species in Australia, there has been much controvercy about the government's intention to release KHV to control carp.  There is more info about the planned release in this blog, and on the internet.  Read the arguments against releasing KHV from one Koi keeper by clicking on the title or picture...

We always talk about our Koi ponds as ecosystems, where our Koi live in harmony with their environment.  In our home ponds, we are trying to reproduce the natural conditions that Koi have evolved for.  But what if you could keep fish and plants on a much smaller scale than a pond?  OK - I know this article isn't about Koi, but it is about a miniature ecosystem that has survived for over 25 years!  I was fascinated, and hope you enjoy this article as much as we here at K.O.I. did!  Read it by clicking on the title or picture...

You can get the link to the paper by clicking on the title or picture above.  Meanwhile, here's what the Fish Vet -Dr.  Richmond Loh - had to say about it:

"The first paragraph is filled with assumptions about carp being a major cause of (rather than carp being a symptom of) aquatic ecosystem damage.

Here it also states that once KHV is released, there will be continued release of more devastating viruses, to kill fish that develop natural immunity.

But what I find most disconcerting is that it says, “the release of CyHV-3 undoubtedly represents a unique and exciting natural experiment…”

Would it be okay for me to say that I’m not in the least bit excited?"
