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!
Can a fish be depressed? This question has been floating around my head ever since I spent a night in a hotel across from an excruciatingly sad-looking Siamese fighting fish. His name was Bruce Lee, according to a sign beneath his little bowl.
Saw this in the pharmacy today - and it's EXCELLENT advice for Koi keepers! It doesn't just apply to humans!
As Koi keepers, we believe that most Koi food has been developed with the nutritional needs of our Koi in mind. But scientists are finding out that there may be a big difference in the nutritional needs of wild fish vs. fish kept in captivity, and perhaps the nutrients in Koi food will change in the near future to make it even more nutritionally beneficial.
Everyone has heard about using algae to replace carbon based oil and fuels, but did you know research is also taking place to use it as food for fish, replacing fish meal in many aquaculture feeds?
It turns out that carp react to very low frequency magnetic fields.
Clove oil is used as an anesthetic for many species of fish, including Koi. Research was done on the effectiveness of clove oil as a muscle relaxant, as well as the timing of induction and recovery.
The entire surface of the fish should be thoroughly examined including the oral and opercular cavities, the nares, gills, and fins.
While the Australians are interested in the effects of the carp die-off caused by KHV, what is of interest to Koi keepers in the USA is the fact that KHV was documented to be around in the wild in the 1990's.

University of Minnesota researchers see a recent fish virus outbreak as a chance to combat an invasive species plaguing state lakes.
As of September 2017, this is the latest and greatest article available anywhere on KHV.
Biological filters are not the only place in the koi pond and filter system where biological filtration takes place. Nitrifying bugs (nitrosomonas and nitrobacter) are prolific in nature, on land, everywhere in the aquatic environment, even in the air but it is only how they behave under water that is of interest to koi-keepers.
What if you didn't have to dissect a specimen in order to see the cells under a microscope? That technology is coming, and in 3D.
This is a great article about a plant that should be used more frequently in planted ponds and tub gardens!
Congratulations to our own Jeff Rasche for placing 3rd in the Grow Out Contest!
We've talked about it before in this blog - but here's more proof that water treatment plants are unable to deal with some of the chemicals found in the water, and that they are affecting our fish. If you are using 'city' water in your pond, this article should be of interest to you. And what about those of us using 'well water' in our ponds - there are no treatment plants for us? Makes you think, especially as our Koi are long-lived pets...
There are many physiological adaptations to stress. Read new research that indicates that stress makes our Koi shy...
How do fish communicate? Read about the latest findings from research...
While this article is about farmed fish, it certainly applies to our Koi. Read the research about the benefits of fish exercise...
When the water temperature is higher, our Koi require more oxygen. Read about how global warming may affect all fish species...
Here's the problem... If you keep Koi of both sexes, they spawn. You get 1000's of babies. If you keep just females, they can die of egg binding - they have to lay their eggs eventually, without males, they tend not to... If you keep just males, you can't show them, and they never grow as large nor do most have pleasing body shapes. So what's a Koi keeper to do? What if we could sterilize Koi? Read about new research that might evntually be of help to Koi keepers everywhere...
In both our Koi and commercial aquaculture, the delivery of antibiotics has been by individual injection. Read about a company that is researching the use of functional feed additives as a replacement to injections...
