A new trend of replacing fish in fish feed, to substituting insects. 
 
French insect farming startup insect is building the world’s largest insect farm in Amiens, north of Paris.

Very, very interesting. included is Ted Talk by the article's author.
 
Every day, corporations like Facebook, Amazon and Google learn more and more about human behavior by collecting incredible volumes of data — what’s called Big Data — on our social behavior. They use it to learn things like how our behavior is influenced by the behavior of other individuals in our social network.
But what if we could do the same thing with animals in nature?

Ahh fish, amazing partners in the Mangrove exosystems!
 
...according to a new study by the University of Michigan, two tropical fish may be mangrove’s ‘most valuable players’ in the pursuit of nutrients - by providing the mangroves with their nutrient-rich urine.

According to this story our Koi get drunk in the winter!
 
During the winter, goldfish and their relatives can have a blood-alcohol concentration beyond the legal limit for drink driving.
Scientists have figured out how goldfish produce alcohol to survive when trapped beneath the icy surfaces of frozen lakes and ponds.Unlike most vertebrates which die within a few minutes without oxygen, goldfish and their wild relatives crucian carp are able to survive for months in low oxygen water.
 

Your koi and the circle of life - oh my:
 
Natural selection doesn’t favor brightly colored fish with predators like ospreys around,” I was told by Jim Levitt, a fisheries biologist with the fisheries division of the Minnesota Department of Natural Resources.

Heron problem: train a crow!
A homeowner has been paying a crow in mealworms for chasing a hungry heron out of his garden after it stole hundreds of pounds worth of fish from his pond. 
Simon McCabe, 51, says the heron has 'emptied' the pond in his back garden of koi carp and goldfish.
But ever since the crow started visiting the garden last month, the little bird has 'looked after' his pond community and he's not lost a fish since.  

If you have chlorine or chloramine treated water, K.O.I. has always recommended the use of a water shut off timer whenever doing a pond refill.  In fact, they are so cheap (and they do sometimes fail, that Spike now recommends using 2 of them, one after the other.

But there is another way that doesn't involve the use of ANY device.  Read what the Fish Vet in Australia recommends.

This short article is the New Zealand government's position about Koi.

Koi should never be released into lakes or streams because of the environmental damage they do.  Read this story about how bad the problem has become in one local lake...

It's kind of like an amazing dream coming to life. Your adorable little goldfish grows into a giant, chasing you around a pond.

Only in this case, 11-year-old Luke Hebb wasn't dreaming when he fished a 16-pound koi out of Lacombe Lake in St. Albert Wednesday morning.
