We have a lot of recent research findings about fish intellegence posted here on the K.O.I. blog.

While this article is about animals, I think it's very interesting!  We underestimate the non-humans around us, and the more we learn, the more we can begin to put everything in perspective.

 Is it time to add algae to your koi diets?  Here is a research article on this subject.
 

This article really got me thinking and I must admit, I do acknowledge the relationships I have developed with my fish. This is a much bigger picture of the relationships we have with other species, and with fish.  
 

If you are interested in the study of biofilm and it's many varities, this is the article for you. 
 

From Science.gov research search: Japanese koi fish:  "Complete mitochondrial genome (mitogenome) sequences were determined for two individuals of Japanese ornamental koi carp. Interestingly, the obtained mitogenomes (16,581 bp) were both completely identical to the recently reported mitogenome of Oujiang color carp from China. Control region (CR) sequences in DNA database demonstrated that more than half (65%) of the koi carp individuals so far reported had partial or complete CR sequences identical to those from Oujiang color carp.

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.
 

So, what do carp do in the Winter? These scientist in Berlin, Germany had some fun by placing 37 tagged and traceable carp in a very cold (7°C, 44.6°F) natural lake during the winter to see what these fish would do. You will really enjoy this short YouTube. 
 

Imagine over 780,000 years ago our ancestors, the genus homo, was cooking the ancestors of our koi over fires in Israel.  In this fascinating research these scientists have found the first evidence "that the fish from the archaeological horizons of Area B had been cooked and consumed on site. This is the earliest evidence of cooking by hominins." I hope you take the time to read this wonder research and marvel at the amzing work that gives us a look into the past.
 

The aqua feed industry is ever changing and as koi hobbyists we are affected, mostly by the changes in the ingredients in koi feed, we often try to follow the trends. Here is a voice in the aquaculture industry speaking out for transparency in the feed manufacturing sector for those who raise fish for a living. Koi Organization International does not take a position on this or other policies of the aquaculture industry, but it is fair to say, that we like other consumers would benefit from clearly understanding the ingredients in our feed that we give our koi.
