Doctor fish in spa - by Dina Middin

The controversial use of live fish to chew away dead skin in pedicures may be banned in New York State for health and safety issues which have been proposed in a new bill.

The procedure in question was actually developed in Turkey, as a way to take care of a variety of ailments of the skin, such as psoriasis, consists of the feet being plunked into a tank of water which contains two different kinds of small fish. These rather hungry fish then proceed to eat away dead skin while leaving the healthy skin alone.

These “Fish Pedicures” are illegal in at least 14 different states, comments Senator Jeff Klein, of the Bronx and Westchester, who originally proposed the ban. The basis of the ban rests on the concern that fungal infections may be passed by unsanitized fish in unclean water. Of course the animal rights groups have jumped on the band wagon, pushing to outlaw the use of fish in pedicures as it is inhumane.

Robin Ross, the president of the New York Podiatic Medical Association, had this to say during a telephone interview: “I do not recommend it to anyone who has any diabetes or any immuno-compromised condition such as AIDS or cancer, because of the risk of infection. The fish are defecating and urinating in that water and you’re sticking your feet in it.” ”

The New York Department of State has gone on the record, saying that it is not aware of any of the 20,000 plus licensed nail salons engaging in such an activity. Apparently it is only being done on the down low, in backrooms of New York City.

Buffalo, New York – The NOLENS (Near shore and Offshore Lake Erie Nutrient Study) is going to be wrapping up the month, after a long year of rigorous research which was headed by Chris Pennuto. Chris Pennuto, a research scientist at the Buffalo State College Great Lakes Center, is a biology professor who has taken an interest in the state of Lake Erie.

The central part of the research was focused on the question “Why didn’t Lake Erie’s health improve as expected when the amount of phosphorus discharged into the lake decreased?”

Other members who were a part of the project were Lyubov Burlakova, a research sicentist associated with the Buffalo State College Great Lakes Center; Alexander Karatayev, who directs the center; and Alicia Perez-Fuentetaja, a research scientist and associate professor of biology.

Back in the 60’s, Lake Erie was all but considered defunct. Ironically, one of the most prominent factors which caused Lake Erie to be in this defunct status was it’s level of nutrients. Karatayev explained, “Nutrients are like calories. You need calories to live, but if you eat too many of them, you can get very, very sick.” One of the nutrients on that list is phosphorous.

For this reason, and a variety of other contributing factors, Lake Erie has huge algal mats still growing on the lake bottom. Pennuto and his team are slowly getting to the bottom of it, and hope to have a plan of action to present soon, to remedy the situation.

The 11 year old snakehead involved in a year-long legal battle with the state Department of Environmental Conservation died Wednesday last week.

Owner Chris Deverso said he stuck his hands in Rocky’s tank when he noticed the fish struggling around 9 p.m. “By the time I found him, it was already too late,” he explained. A water test carried out by Deverso revealed nothing unusual and there aquarist had not noticed any signs of disease.

Deverso said snakeheads can reach an age of 10-15 years in the wild.

Since 2004, it is illegal to keep sneakheads in New York. In June 2009, Deverso was finally given a permit to keep Rocky provided that he kept the aquarium locked.

Deverso is now looking for a taxidermist to have the body preserved.

“This isn’t a goldfish you get at the fair and flush down the toilet,” he said. “I’ve got 11 years of stories with him. I want him to always be with me, to always be talked about.

Rocky, a snakehead living with its keeper Chris Deverso in New York State, might get a new lease on life.

Snakeheads are Asian predatory fishes capable of breathing oxygen from the air and move over land. They have been banned in the USA since they might wreck havoc with North American ecosystems if introduced to the wild.

Due to this regulation, the Department of Environmental Conservation wanted to euthanize the pet snakehead, but Deverso – who has owned the fish since before the ban was put into action in 2004 – refused to give up his pet and has therefore been back and forth to court and fined for owning the illegal fish.

The Department of Environmental Conservation has now offered a compromise; they will grant Deverso an educational permit, provided that he fulfils the educational permit requirements. He must:

– Install a lock on the top of the aquarium.

– Holds an open house or lecture in his home for groups interested in learning about snakehead fish.

– Pay an annual permit fee of $500.

“I never went to college; I never made much. I’m just an average guy who stood up for what I believed in and hopefully in time I’ll be granted the permit and it’ll all be worth it,” said Deverso. “I’ve taken care of him for 11 years, it’s my family pet; $500 is a lot of money but if it saves his life, it’s worth it.”

Acesulfame K passes through the human body into wastewater, survives water treatment and accumulates in groundwater, Swiss researchers have found.

Acesulfame K turned out to be much more resilient towards treatment than saccharin, sucralose, and cyclamate – three other popular and commonly used artificial sweeteners.

The scientists tested tap water, urban groundwater, and both treated and untreated water samples from 10 different wastewater treatment plants. They also collected water samples from four rivers and eight lakes near Zurich and from a remote alpine lake.

In the untreated wastewaters, they could detect the presence of all four sweeteners (acesulfame K, saccharin, sucralose, and cyclamate), but in treated water 90% of saccharine and 99% of cyclamate were eliminated. Sucralose withstood treatment somewhat better, but the concentrations were still small. Surprisingly enough, acesulfame K proved much more resilient towards treatment and the equivalent of 10 milligrams per person per day could be detected in both untreated and treated waters.

Treated water often end up in lakes and rivers and no one knows whether acesulfame K has any impact on fish or the environment.

“These concentrations are astronomically high,” says Associate Professor Bruce Brownawell, an environmental chemist at Stony Brook University, New York “If I had to guess, this is the highest concentration of a compound that goes through sewage treatment plants without being degraded.”

The research team found no detectable amounts of artificial sweeteners in the remote alpine lake, but in the other rivers and lakes the amount of acesulfame K increase proportionally with nearby human population sizes. Acesulfame could also be detected in 65 of 100 groundwater samples and small amounts of the sweetener were also present in tap water. The levels detected are not considered detrimental to human health and were far too low to change the taste of the water.

The study has been published in the journal Environmental Science & Technology .

When Kate Stoeckle, 18, and Louisa Strauss, 17, collected samples of fish from New York fish stores and restaurants on Upper Manhattan and tested them using the new genetic barcoding method, an astonishingly large portion of the samples turned out to be mislabelled and sold under the wrong name. A sushi restaurant claiming to offer white tuna was for instance serving their guests Mozambique tilapia instead, while another restaurant sold Spotted goatfish from the Caribbean Sea under the name Mediterranean red mullet.

Red Snappers

All in all, Stoeckle and Strauss collected 60 different samples of fish and had them tested at the University of Guelph in Canada. Four samples could not be identified by the genetic barcoding identification technique, but of the remaining 56 samples no less than 14 turned out to be mislabelled. This means that out of 56 samples, a whooping 25 percent were sold under false pretences.

All 14 cases of mislabelled fish consisted of comparatively cheap fish being sold as a more expensive species. It is therefore hard to see how the mislabelling could be the result of honest mistakes by fishermen or middlemen.

Not getting what you pay for as a consumer is however not the only problem with mislabelled fish; a false identity can also be used to sell endangered species to unsuspecting dinner guests. In the Stoeckle and Strauss study, two samples of alleged red snapper did for instance turn out to be endangered Acadian redfish (Sebastes fasciatus). The Acadian redfish has been listed as Endangered (EN) on the IUCN Red List of Threatened Species since 1996.

The study did not unveil the names of the restaurants and fish shops since it could not be determined if they were intentionally misleading their customers or if they had purchased the mislabelled fish in good faith.

Stoeckle and Strauss are both students at New York’s Trinity school.
