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!

The pond-dwelling carp (Cyprinus carpio). Foreign strains of carp from the Eurasian continent have invaded many bodies of water within Japan, and native Japanese carp are becoming rare.  Read how they tell the 2 apart by clicking on the title.

New research suggests that every player in a community is important, to varying degrees, for ecosystem functioning into the future.  Read the article 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.

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.
