Feed - Food, Feeding

A good article on supplementing your koi's diet, however, CAUTION - feeding your koi live food is highly discouraged.  Live food has a high probability of bringing viruses and pests into your pond. For this reason, K.O.I. never recommends live food for your koi.  
 

UConn students learning about "koi people" as they work with a fish food manufacturer. 
 

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.

This factory is not far from where I live so I wanted to include this story. The feed industry is changing fast and bringing changes to the ingredients that consumers will see in fish feed.
 
 
JEROME, IDAHO — Scoular has given an official name to its upcoming barley protein concentrate (BCP) ingredient: Emerge™. Emerge will serve as a sustainable, traceable and non-GMO protein alternative for pet food and aquaculture manufacturers, and “the only barley-based protein for feed customers,” according to the company.
 

The future of fish feed continues to evolve.  How will it change what we feed our koi?
 
Veterinarians from RUDN University have developed a way to increase the resistance of carp, the most common fish in fish farms, to the harmful effects of ammonia, which is found in almost all water bodies. The researchers found that the amino acid arginine added to fish food can be helpful. The results are published in the journal Aquaculture.
 

A short, but very interesting study in ammonia eating bacteria, and how frequency of feeding affects ammonia rates in water.  
 
..."Feeding leads to a peak in the ammonia production. For the symbiosis between fish and bacteria, it is better if the ammonia production is more constant. It is therefore better to feed often with small amounts than with large amounts once or twice a day. The bacteria -- and therefore the fish -- benefit from this feeding tactic. Nearly all organisms benefit from constancy."
 

Its been coming, fish food without the fish. 
 
Dartmouth scientists have created a more sustainable feed for aquaculture by using a marine microalga co-product as a feed ingredient. The study is the first of its kind to evaluate replacing fishmeal with a co-product in feed designed specifically for Nile tilapia.

Okay, will someone tell me how to make this food.

Another story on fishless fish food. 
 
After six years of research, a team of scientists at the University of California, Santa Cruz has developed a cost-effective new aquaculture feed that eliminates conventional fish meal and fish oil ingredients while also providing better fish weight gain and higher nutritional value in the filet for humans. The new fish-free feed is the first to demonstrate across-the-board gains in sustainability, performance, economic viability, and human health.
