Polluted Lake Qaraoun Spews Out Tons of Dead Fish


Tonnes of dead fish have washed up on the shore of a highly polluted lake in eastern Lebanon in the past few days, an official said Thursday.

It was not immediately clear what caused the fish kill in Lake Qaraoun on the Litani river, which several local fisherman said was unprecedented in scale.

A preliminary report said a virus had killed only carp in the lake, but a veteran water expert said their deaths could also have been caused by pollution.

Hundreds of fish of all sizes lay dead on the banks of the more than five kilometre (three mile) long lake Thursday, and the stench of their rotting flesh clung to the air.

Men shovelled carcasses into a wheelbarrow, as a mechanical digger scooped up more into the back of a truck.

"It's our third day here picking up dead fish," said Nassrallah el-Hajj, from the Litani River Authority, dressed in fishing waders, adding they had so far "carried away around 40 tonnes".

On the water's edge, 61-year-old fisherman Mahmoud Afif said it was a "disaster".

"In my life I've never seen anything like it," said the father-of-two.

The Qaraoun lake was built as a reservoir on the Litani river in 1959 to produce hydropower and provide water for irrigation.

But in recent years experts have warned huge quantities of wastewater, industrial waste, and agricultural runoff containing pesticides and fertiliser flooding into it have made it increasingly toxic.

- 'Toxic bloom'? -

Since 2018 fishing has been forbidden in the reservoir as the fish there was declared unfit for human consumption, though fish from the lake have continued to appear in several markets.

The Litani River Authority and the Society for the Protection of Nature in Lebanon on Friday warned of a "viral epidemic", and called for fishing to be forbidden in the Litani as well as in the lake.

It said the likely disease had only affected carp, while four other types of fish appeared to be unaffected.

Kamal Slim, a water expert who has been taking samples of water from the lake for the past 15 years, said pollution could also be the cause.

"Without analysis, we cannot be decisive," said the researcher.

But the lake is also home to cyanobacteria, or blue-green algae, and in warmer months the excess nutrients from pollution have caused the bacteria to erupt into bright green blooms that release toxins.

"Right now there is a cyanobacteria bloom, though less thick than last year," he said.

That or a bacteria could be responsible for harming the fish, especially since they are weaker during the reproduction season.

"Another possibility is very toxic ammonium," he said.

In July 2016, Lebanese media reported that tonnes of fish floated to the surface overnight in the Qaraoun lake.

Slim said that was due to a toxic bloom and oxygen depletion.

Americans are some of the worst polluters in World history.

واليوم أعلن مدير عام المصلحة الوطنية ل​نهر الليطاني​ ​سامي علوية​، أنه “عثرنا على 80 الى 90 طن الاطنان من الاسماك النافقة حتى الآن، وبحسب ما نحن أكيدون منه فإنه تم تحويل أكثر من 7 طن من الأسماك النافقة الى السوق وبيعها للمواطنين بالأيام الماضية من قبل مجهولين على أساس أن السمك تم اصطياده فيما هو سمك نافق غير صالح للإستهلاك البشري وهو خطر على ​الصحة​”.

It’s so criminal, if it kills a fish, it’ll poison humans or at the very least start a long lasting disease.
Sick people.
