Great work on memory of goldfish. We know our koi can do even better.
"It’s long been a common belief that fish have the memory capacity of only a few seconds. People often make fun of people with bad short-term memory by saying they have the “memory of a goldfish.”
Yes, and we have all seen koi in cramped tanks, too small of ponds without adequate filtration and oxygen. Another reason Koi Organization International (K.O.I.) exists.
K.O.I. is an international group of expert hobbyist-volunteers who want to promote FUN in the Koi hobby by teaching all aspects of Koi and pond keeping, with a focus on Science.
PARIS, Jan 22 (Reuters) - A leading French aquarium vendor has decided to stop selling round fish bowls because they drive fish mad and kill them quickly.
You don't need to read the entire article to find the tidbit about koi - it right below for you - but it is an interesting article.
Now this is interesting; do our koi do the same?
A team of researchers at the University of Oxford has found via experimentation that goldfish use markings on the floor below them to measure how far they have traveled. The findings are published in Proceedings of the Royal Society B.
Koi seem to have their own way of swimming as studied and described in this research by Wu, Yang and Zeng. If you are into kinematics and hydrodynamics this is the reseach paper for you.
This reseach gives "frozen fish" a whole new meaning. My wonder is if the Crucian Carp's cousin the koi is able to revive the same? For those loving a scientific article, you will love this.
Crucian carp (Carassius carassius) survive without oxygen for several months, but it is unknown whether they are able to protect themselves from cell death normally caused by the absence, and particularly return, of oxygen....
This young man is not only a brilliant scientist with an amazing future ahead of him, but we at Koi Organization International (K.O.I.) are proud to call him one of our own. Indeever congratulations on your significant contribution to fish science and adding the knowledge of the genome of angelfish. But we also appreciate that you are a Certified Koi Keeper (CKK) with Koi Organization International. We at K.O.I. look forward to continuing to highlight your future scientific work.
Wow, I never knew. This is a great article, and for the more science minded, read the entire research paper. Both article and research links provided below.
"Every winter, the northern European crucian carp gets frozen into the ice, and receives no oxygen. Every spring, when the ice melts, a seeming miracle occurs: the fish emerges from the ice and resumes normal life....
Are you being careful enough about keeping your beautiful water plants, and aquatic life from spreading into your local waterways! In the local river in my community countless hours and $$$ are spent in ridding our river of plants and animals that should never have been introduced to our river and now cause problems for native life and the health of the river. Though this article comes from Michigan State University Extension, its message is for everyone who keeps a water garden with plants and aquatic life. Let's keep them in our ponds and not let them escape to ruin our local water
!If you're not havin' FUN, you're not doin' it right
