A Koi Club contact from a monastery and the saving of a pond and its koi.
Depending where you live in the world, your pond will have different critters that can been seen if you look close. Here are some from Britain.
Summer is a time to leave your pond and its wildlife in peace. However, by looking at your pond at night, you might be surprised at what creatures come out when the sun goes down.
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."
A noted downside to keeping both koi and goldfish together.
The eye-attacking behaviour of Koi fishes was recorded in a koi–goldfish polyculture system. The attacked fishes suffered from eye ablation, abnormal swimming and suppressed feeding behaviour. There was a significant difference in mean sizes of victims and attackers but the exact motivating stimuli for the observed action was not clear. For future research, the effects of different stocking ratios on aggressive behaviour of koi should also be examined.
What a beautiful sight, and for all to enjoy.
Scientific research about swimbladder disorder for koi. So for our very scientific minded koi lovers, this one is for you.
As pond owners and koi hobbyests, we all hate to see this in the news!
ST. GEORGE, Utah — Dumping unwanted goldfish or other aquatic pets into reservoirs might seem like a humane way to dispose of them, but these invasive species can wreak havoc on fisheries, the St. George News reports.
Something we all dread as pond owners, and then we must solve the mystery.
On Saturday, eight days after the die-off at Danly’s house in North Coconut Grove, her neighbors awoke to a similar ghastly sight. Lee Marks and Daliana Mantegazza, koi collectors for 30 years, lost about 150 of the fish prized for the exotic coloring that makes it look like they’ve been painted. The sobbing couple and their sons frantically tried to save them by jumping into the pond and transferring fish into bins filled with fresh water. Only a dozen survived.
Humans have been the only known species to domesticate other animals - until now.

In our new study, we describe what appears to be first example of a non-human vertebrate domesticating another animal...
