Research can change lives and this story is about common genetic mutations in zebrafish and humans with Fragile X syndrome and autism. 
 
Queensland Brain Institute’s Associate Professor Ethan Scott and Dr Lena Constantin used zebrafish that carry the same genetic mutations as humans with Fragile X syndrome and autism, and discovered the neural networks and pathways that produce the hypersensitivities to sound in both species.
 

In a recent study, an international team of researchers analyzed fish bones excavated from the Early Neolithic Jiahu site in Henan Province, China. By comparing the body-length distributions and species-composition ratios of the bones with findings from East Asian sites with present aquaculture, the researchers provide evidence of managed carp aquaculture at Jiahu dating back to 6200-5700 BC.

Common carp were part of this study that looked at the dynamics of scales and drag for airlines.  Scale design may provide significant saving in fuel for planes. 
 
The team's findings have been published in Nature: Scientific Reports: "Transition delay using biomimetic fish scale arrays," and in the Journal of Experimental Biology: "Streak formation in flow over biomimetic fish scale arrays."
Reducing drag means faster aircraft speeds and less fuel consumption—an important area of study for aerodynamicists...
 

Fish fins aren’t just for swimming. They’re feelers, too. The fins of round gobies can detect textures with a sensitivity similar to that of the pads on monkeys’ fingers, researchers report November 3 in the Journal of Experimental Biology.

An important article on Australian invasive carp and plans to kill by KHV.
 
International researchers and local experts describe the federal government's plan to release Kopi Herpesvirus into the Murray-Darling Basin as "madness", saying the science is still out on its safety and effectiveness.
Researchers say plans to release a virus to reduce numbers of invasive Common Carp in Australian waterways should be abandoned. 

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.

I wonder when we will see nuts in our koi feed?
 
Thanks to researchers at the Agricultural Research Service, a new feed ingredient made from tree nuts is available to fish farmers.
As the aquaculture (fish or shellfish farming) industry grows, so does the need for fish feed that's not dependent on the stagnant supply of fish meal made from captured marine fish protein and oils.

Another story on the research about fish and their amazing intellect. 
 

Most people think of fish as somehow lesser than pigs, cows, chickens and other land animals.
