 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. 
 
 

So much to still discover in our world, even when in plain sight. 
 
"The largest waterlily species in the world has been discovered after a case of mistaken identity that saw it hide in plain sight for 177 years.

Wow, this technology could be right around the corner for us hobbyists. I am keeping my fingers crossed for a "affinity silk filter". 
 
Abstract

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.
 
Abstract

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.

If you wonder why your koi feed is incorporating so many newer ingredients, read this article.  The urgency for self- sustaining feed is because our need to feed fish; both hobby and commercial aquaculture is driving harmful fishing practices around the world.  
 

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."
 

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. 
 

Another loss of habitat for a branch of the carp family. This short article shares a bit about lost carp species and the people who depended on them for food. 
 
"Just two species of the freshwater fish still exist in the ancient waters of Lake Lanao in the Philippines after predatory fish were accidentally introduced
