As the koi hobby grows and the need for expanded specialized veterinary care becomes evident, more diagnostic procedures are needed. Here is an example of researchers using endoscopic evaluation on koi.
Matt Parker is a Senior Lecturer in Neuroscience and Psychopharmacology, University of Portsmouth, where he studies fish and fish behavior. Over his career he has some observations about fish and human beings. I know you will enjoy this easy read, short article on how we humans are like our fellow fish.
Wow, this technology could be right around the corner for us hobbyists. I am keeping my fingers crossed for a "affinity silk filter".
A fascinating study suggesting that koi will self-seek water at 90 deg F (32 C) in order to reduce the suffering of KHVD (cyprinid herpesvirus 3). This is very exciting research, but of course as noted by the researchers out of Belgium, a vaccine is still needed.
Behavioral fever, something newly defined in the behavior of koi/carp. What a great article on the study of the Cyprinid Herpesvirus3 (CYHV-3), also known as KHVD, and how water up to 90 degree F (32C) is used for treatment. Though a vaccine is still needed, this study showed that fish will self-select this high temperature water to cure themselves. "It's been known for a while that fish (and other animals that can't generate heat internally) could help their immune systems fight off infection by moving to a warmer spot.
For those of us who are koi hobbyist, we have a great appreciation for the intelligence of our fish. Scientists, now studying more of the aquatic world and are researching the powers and intelligence of our finned friends. Another review of a study regarding the memory of fish.
"It is popularly believed that fish have a memory span of only 30 seconds. Canadian scientists, however, have demonstrated that this is far from true -- in fact, fish can remember context and associations up to twelve days later."
A reminder that koi can live quite a bit of time out of water. I had an unfortunate situation when a young koi leapt from the pond, and in the morning finding it unresponsive (and presumed dead), I placed back in water and gently massaged and moved in the water to reintroduce water running through the mouth. I still have this koi, called Phantom, in my pond today.
For our more scientific readers, a study on long fins and how they were passed from one generation to another. Included is just a bit of history of the developement of the butterfly koi.
I think my pond and koi could use a few more of this type of bacteria! A very interesting study, enjoy.
This fish, that soon was know as Carrot, was put in this Fishery in France 20 years ago.
The article states "The fish is a hybrid species of a leather carp and a koi carp, which are traditionally orange. It's believed to be the second largest of its type caught.
"The angler posed for a snap with his catch before releasing it safe and well back into the lake. He celebrated with a cup of tea afterwards.
