Monterey Bay Aquarium asks top chefs to help restore marine life
The Monterey Bay Aquarium has launched a national campaign asking top U.S. chefs and culinary decision makers to take a “Save Our Seafood” pledge not to serve items listed in the “avoid” section of the Monterey Bay Aquarium Seafood Watch List.
Deletion of single molecule makes fish switch to violet vision
Researchers from Emory University have identified the first fish to have switched from ultraviolet vision to violet vision, i.e. the ability to see blue light. This fish in question – a type of scabbardfish – is also the first example of an animal where a deleted molecule has resulted in a change in visual spectrum.
World’s first semi-cloned fish created in Singapore
A research team from the National University of Singapore announced this week that they have created the world’s first semi-cloned fish – a female medaka fish named Holly.
Caribbean fish travelling in style
The National Marine Aquarium in Plymouth, UK has received some attention in the press after chartering a Boeing 767 to fly in a 42-tonne cargo of Caribbean fish for a new exhibition.
When opposites won’t attract; same-colour medakas preferentially selective for each other
An international team of researchers have shown how one single gene mutation is capable of making the medaka, a Japanese killifish, loose its attractive colours and display a drab grey colour which renders them significantly less attractive to medakas of the opposite sex – unless that potential mate is grey too.
How to tell if a salmon is wild or farmed?
Telling a wild salmon from a farmed one can be tricky, especially if you don’t want to kill or injure the fish in question. To solve this problem, Dr Elizabeth Adey of the Scottish Association for Marine Science (SAMS) have developed a way of using fish scale analysis to determine the origin of a salmon.
Mexican researchers breed gar in captivity using new sexing technique
The gar family, famous for containing the largest fresh water fishes in Mexico, is currently at risk of becoming extinct – something which Mexican researchers are working hard to prevent.
Flatfish – how did its eyes get to the same side of the head?
If you’ve ever wondered how the eyes of flatfish like flounder and sole ended up on one side of the head, you should take a closer look at a newly published article by Dr Matt Friedman.
Tuna stocks expected to recover by 2013
According to Australian Southern Bluefin Tuna Association chief executive Brian Jeffriess, industry experts expect the tuna stocks to have recovered by 2013.
Researchers improve zebra fish cloning – “We used the same entrance that sperm uses”
A team of scientists at the Michigan State University has found a new, more efficient method for cloning zebra fish.
Bottom-feeders let loose in foreclosed Floridian homes
The Floridian town of Wellington used to spend nearly 7,000 USD a month of taxpayer funds to keep the stagnant pools of foreclosed homes sanitary.
Pufferfish responsible for dog deaths in New Zeeland
The mysterious deaths among dogs visiting the beaches of Auckland have now been solved; they were caused by tropical pufferfish.
Babelfish?
aring impairment caused by damage to hail cells in the inner ear is by far the most common cause of hearing loss, but research carried out on Zebrafish might be able to show us how these hair cells can be re-grown.
Will the future bring us Japanese super tuna?
A Japanese team of scientists are now announcing that they are close to completing genome sequencing of the Bluefin tuna. Once they have reached this goal, their next project will be to use their knowledge to create a tuna breeding program for a new type of tuna specially designed for aquacultures.
