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!

A great overview of what feed ingredient alternatives are being researched as a substitute for costly fishmeal in fish feed. 
 
Discussion and research implications

Creative use of wasted flare gas to help grow microbes for fish feed. I wonder how this will look on a bag of fish food ingredients?
 
...The company plans to capture methane from flare gas in the oil-and-gas sector in Alberta and convert it on site into methanol. It will then be transported to a production facility where the methanol will feed and grow microbes in bioreactors.
 
...Later this month, the Center for Aquaculture Technology will test DeNova-treated pellets in adult Atlantic salmon completing a life-cycle evaluation of the fish.

Okay, now I am carefully looking out for red eyed carp.  Do you have one?  
 
The purpose of this study was to investigate the inheritance of red eyes in ornamental koi, a variant of Common Carp Cyprinus carpio. The study included crossing fish with different eye color phenotypes and analyzing fish segregations in progenies.

For our science minded friends!
 
...The study reveals the details of important nutrient exchanges between algae and bacteria. Such exchanges determine the functioning of microbial communities in the environment, relevant to climate change cycles and agricultural productivity. Microbial interactions within microbial communities are important on many levels, ranging from the ecology of aquatic and terrestrial food webs, to wastewater treatment. A key characteristic of the interactions within these communities is the exchange of nutrients between species.
