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 oxygen-free water.

Biologically speaking, the fish convert their anaerobically produced lactic acid into ethanol which diffuses across their gills into the surrounding water.

The researchers from the Universities of Oslo and Liverpool have discovered the unusual molecular mechanism behind this unique ability.

  Mexican authorities seize illicit alcohol in crackdown at resorts Mexican authorities swept through 31 resorts, restaurants and nightclubs in Cancun and Playa del Carmen in recent days, suspending operations at two for unsanitary alcohol and in the process discovered a sketchy manufacturer that was supplying tourist hot spots. Regulators seized 10,000 gallons of illicit alcohol from the company, noting its “bad manufacturing practices,” according to government officials. They did not release the company's name.

They have pinpointed sets of proteins which are normally used to produce energy by channelling carbohydrates towards their breakdown within a cell's mitochondria.

While one set of those proteins is very similar to what other species of vertebrate possess, the second set is uniquely activated by the absence of oxygen.

Dr Michael Berenbrink, an evolutionary physiologist at the University of Liverpool, said that the blood alcohol concentration in these fish can exceed the drink-drive limit during the winter.

During the winter , goldfish and their relatives can have a blood- alcohol concentration beyond the legal limit for drink driving. 0. 0. Continue Reading - Via news.sky.com.

"During their time in oxygen-free water in ice-covered ponds, which can last for several months in their northern European habitat, blood alcohol concentrations in crucian carp can reach more than 50mg per 100 millilitres," said Dr Berenbrink.

"However, this is still a much better situation than filling up with lactic acid, which is the metabolic end product for other vertebrates, including humans, when devoid of oxygen."

Lead author Dr Cathrine Elisabeth Fagernes, from the University of Oslo, said: "The ethanol production allows the crucian carp to be the only fish species surviving and exploiting these harsh environments.

"Thereby avoiding competition and escaping predation by other fish species with which they normally interact in better oxygenated waters.

"It's no wonder then that the crucian carp's cousin the goldfish is arguably one of the most resilient pets under human care."

Then that glass of wine would carry over into me having one before the awards show, and then a bunch at the awards show." she says. "Then I felt bad for making kind of an a** of myself to people that I really respected. And that feeling, there's just nothing like that.
