The amazing powers of bioflim and it's future potental.
Researchers have demonstrated that a slimy, yet tough, type of biofilm that certain bacteria make for protection and to help them move around can also be used to separate water and oil. The material may be useful for applications such as cleaning contaminated waters.

Amazing research about damselfish domesticating shrimp!
...Now, researchers have discovered fish that seem to be using shrimp in the same way we would use a farm animal.
The team thinks it could be the first example of a vertebrate species – other than human – domesticating another animal.

An interesting story of tossed out goldfish in a lake and its consequences.
The most likely culprit behind the invasive species? Pet owners who illegally dumped goldfish, officials say.
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.
Insects are now in dog food, is it in your koi food now?
This past Tuesday (June 11), Dutch company Protix opened the world’s largest insect farm in Bergem op Zoom, a small town in the south of the Netherlands.

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. Set to open in fall 2022, per TechCrunch, the facility will focus on raising mealworm beetles — specifically their larvae— for commercial uses, including fertilizer and as food for pets and aquaculture.

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.
