Sewage equivalent to 8.8 million people goes untreated straight into the sea

The Norwegian fish farming industry is not required to clean fish secretion and organic matters so sewage similar to that of 8.8 million people is released straight into the sea.

The Environment Agency sent a robot with a video camera down to 280 meters deep under one of the fish farm facilities west of Bergen. You can see the result of this in this video link (copy the link and Google it) http://www.dagbladet.no/2010/03/24/n...nsing/10963831/

“The entire system is a several metres thick cake of s***, "says Kurt Oddekalv, the leader of the Norwegian Green Warriors. “While we need to purify the sewage from each house being built in Norway, goes this filth directly into the sea”, he says. Kurt Oddekalv dishes criticism of the aquaculture industry, and believes they should pay to clean the sewage from the pens themselves.
In comparison, every Norwegian household paid on average NOK 2,920 a year in sewer levy last year. Aquaculture industry does not pay anything.

The calculation is based on figures from the Climate and Pollution Control Directorate (KLIF) which shows that the emissions of organic matter from a medium-sized fish farm with production of 3,120 tonnes of salmon, equivalent to a sewage spill from a city of around 50 000 people.

Manager for statistics and marketing of the Fisheries and Seafood Association, Jon Arne GrÝttum, says according to Dagbladet newspaper that it is now around 550 000 tonnes of farmed salmon in Norwegian pens in total, but that varies from month to month.

Heidi Sorensen, the deputy minister for Environment is surprised over the figures, and will look into the matter. “These figures are so large that it may be a reason to look at this again”, she says to the newspaper. She also believes it is a good principle that we should treat emissions, regardless of the source it comes from. On the basis of the figures that have come to light, there may be a reason to get KLIF to review this again, "says Sorensen.

The Climate and Pollution Control Directorate proposes stricter environmental standards for Norwegian fish farms. - We cannot comment on individual cases, but we do not want it to look like this. We are concerned when we see this kind of images, "says the Head of water section of KLIF, Anne Sundbye. She also points out that aquaculture is the major growth industry in Norway and that last year’s growth was nine percent.

- We therefore propose measures to limit emissions in areas where there is risk that environmental goals are not reached. In addition, we suggest that fish farmers themselves must conduct environmental studies to document that the operation is prudent, "says Sundbye to Dagbladet newspaper. This industry is an industry that operates in open cages, and thus, there is a limit to what requirements can be set to the cleaning measures, Sundbye says. She also says that the Climate and
Pollution Control Directorate will assess the current technical cleaning solutions, but that so far have not seen any that provide certified cleaning effect.

She explains that there is basically no difference in emissions of organic matter from humans and from fish farms in terms of impact on the environment. - It can cause eutrophication and thick sludge in the environment, and organic matter is organic matter, no matter what business they come from, she concluded.

Oddekalv believe it is possible to clean the emissions from fish farms. “ It is clearly possible to collect the shits. But it will cost " he says. He believes the solution is that the industry will be required to build sealed pens in the sea, and that the emissions can be sucked up and taken to shore and dried. He believes dense plant would also resolve several other issues. Water from 50 meters depth can be pumped into tanks and the clean seawater circled, thus also preventing the infection of sea lice” says Oddekalv. Oddekalv suggest that the industry should be required to build closed construction (tanks) within three years. “This is the last heavy industry who get away with dumping discharges directly into the sea” said the leader of the Green Warriors of Norway Kurt Oddekalv, to Dagbladet newspaper.
