The keeping of "live" creatures has always had the potential to be heartbreaking, and many of us hobbyist have had our tragic tales of loss and failure. Sadly this failure will set this effort to save the endangered chinook salmon back for years.
About 21,000 fish, including sturgeon and endangered chinook salmon, died of chlorine exposure in a "catastrophic failure" at a UC Davis research facility, university officials said Thursday.
Okay it is fun to watch, but there is a bad side to this hitchhiker: eye damage to the koi.
"Toad attached to the fishes eyeballs and damaging them. It buried it’s front legs in the eye sockets. I had to pull out the toad."

Wow, this technology could be right around the corner for us hobbyists. I am keeping my fingers crossed for a "affinity silk filter".
Abstract
If you wonder why your koi feed is incorporating so many newer ingredients, read this article. The urgency for self- sustaining feed is because our need to feed fish; both hobby and commercial aquaculture is driving harmful fishing practices around the world.
Our hobby of koi keeping began several centuries ago in Japan, and in this country, there is a different way of looking at the evolving seasons. I would like to share this beautiful video with you that depicts the 72 micro-seasons as defined by the early Japanese culture. The video is slightly over 4 minutes and very worth your time. It invites you slow down and watch nature; please enjoy these few minutes away from the rush of your day.
This fish, that soon was know as Carrot, was put in this Fishery in France 20 years ago.
The article states "The fish is a hybrid species of a leather carp and a koi carp, which are traditionally orange. It's believed to be the second largest of its type caught.
"The angler posed for a snap with his catch before releasing it safe and well back into the lake. He celebrated with a cup of tea afterwards.
Another loss of habitat for a branch of the carp family. This short article shares a bit about lost carp species and the people who depended on them for food.
"Just two species of the freshwater fish still exist in the ancient waters of Lake Lanao in the Philippines after predatory fish were accidentally introduced
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
A reminder to never release any pet fish into a river, stream or lake.
