The research around fish and the production of fish for consumption is growing rapidly.  Since the common carp is a major source of food for human in many parts of the world there are many studies becoming available on how those in aquaculture can become more successful and productive. In this study Quercetin, a plant pigment (flavonoid) and supplement that is found in many plants and foods, such as red wine, onions, green tea, apples, and berries is tested for its use supporting carp as they grow.

A very good article written by Valentin Thepo’t, a recent PhD student in Aquaculture who looks to identify the potential of aquafeeds and the field's sustainability. This will of course have a direct impact on the feed we serve our koi in the future. 
"The aquaculture industry must continue in its quest to become more sustainable, with greater use of seaweeds in aquafeeds and production of herbivorous fish among two of the most promising avenues to achieve this."

This is another example of how our hobby is growing and expanding the need for a more scientific approach to treating and medicating koi. 

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.

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.

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. 

This reseach gives "frozen fish" a whole new meaning.  My wonder is if the Crucian Carp's cousin the koi is able to revive the same? For those loving a scientific article, you will love this. 
Crucian carp (Carassius carassius) survive without oxygen for several months, but it is unknown whether they are able to protect themselves from cell death normally caused by the absence, and particularly return, of oxygen....
