Mass fish deaths in Korat river probed

The Nation on Sunday

KORAT: -- Officials in Nakhon Ratchasima's Muang district yesterday speedily removed some 100,000 dead fish from a 3-kilometre-long stretch of the Lam Takong River, and collected fish and water samples to determine the cause of the deaths. The results of tests are due out in a week.

The most likely causes of the incident, which started on Friday and worsened yesterday, were believed to be a factory releasing untreated wastewater, reckless people dumping used engine oil into the river or heavy downpours. Municipality water-quality official Rachan Theerapittayatrakul said the fish died from acute lack of oxygen. He said the dissolved oxygen level was 0.9 milligram per litre - and fish die when the level falls below 2 mg/litre. A large amount of engine oil was found in the river.

Freshwater Fish Research Centre director Charoen Udonkan said the deaths might have been the result of a chemical release, because the water remained clear and many fish that could stand the low-oxygenic environment survived. The centre will soon release 200,000 fish into the area to replace the dead ones.

I am surprised this event made it to the news, with the Thai peoples and industries total disreguard for the enviroment. Their rivers and Ocean get it the worst. It all eventually ends up there.

This really makes tourist want to return. Made me sick to my stomach, Beach road @ soi 8 Pattaya

This is from storm drain waste being released into the bay. There is no proper y treatment, and the water in these drains is absolutely putrid.

[jaltsc]

The best clue they have so far for the deaths of the fish is that a Portuguese male was seen fleeing from the river.

Correct.

Like I said it all eventually ends up in the rivers and in the sea. To be fair to Pattaya, their beaches are not the only ones that look this way, wich is very sad.

On this particular occasion, I watch the umbreela vendors burrying the trash in the sand, of course there is trash bins all the way down beach road, but i gues more easy to burry the trash, rather than throw it it the trash bin.

[meatboy]

started fri.and this is sun.what about all the people that buy fish at the local mkts.because bet your bottom dollar some will end up there.its only a few weeks ago our water was affected by factory dumping toxic waste into the source but we were not told only found out a week after.but dont worry we are going to put 200,000 fish in the river to replace them.have they any idea how long it takes for the water to be clean again.having been a fisherman all my life i have seen first hand what these wastes can do.

[Thai at Heart]

Probed.

Nice euphemism for looked at and largely go unnoticed.

[MJP]

It'll be a food or biocrop manufacturing waste with a high biochemical oxygen demand, something >20,000mg/l BOD5. Something went wrong with an anaerobic digester or trickling filter water treatment plant somewhere upstream.

Or a pesticide, lamdacyhalothrin or similar with incredibly high aquatic toxicity has been dumped or applied at the wrong dose close to the water body.

[craigt3365]

I removed a few posts. The reference to Pattaya is a bit off topic, but I'll leave them as is. The posts discussing the merits of these posts have been removed from view. Lenny is right though. Please stay on topic. This is not about Pattaya.

[thequietman]

Suicide perhaps ?

[AleG]

The cause of dead for the 100.000 fish has been established as "coincidence".

[zydeco]

Suicide perhaps ?

Yeah, maybe. I know how they feel.

[Reasonableman]

The term fish kill, known also as fish die-off and (in Britain) as fish mortality, is a localized die-off of fish populations which may also be associated with more generalised mortality of aquatic life. The most common cause is reduced oxygen in the water, which in turn may be due to factors such as drought, algae bloom, overpopulation, or a sustained increase in water temperature. Infectious diseases and parasites can also lead to fish kill. Toxicity is a real but far less common cause of fish kill

Fish kills may result from a variety of causes. Of known causes, fish kills are most frequently caused by pollution from agricultural runoff or biotoxins. ecological hypoxia (oxygen depletion) is one of the most common natural causes of fish kills. The hypoxic event may be brought on by factors such as algae blooms, droughts, high temperatures and thermal pollution. Fish kills may also occur due to the presence of disease, agricultural and sewage runoff, oil or hazardous waste spills, sea-quakes, inappropriate re-stocking of fish, poaching with chemicals, underwater explosions, and other catastrophic events that upset a normally stable aquatic population. Because of the difficulty and lack of standard protocol to investigate fish kills, many fish kill cases are designated as having an 'unknown' cause.

And of course there's the tourist,

that have the time to clean up some of the trash on the beach as they walk along the beach .

But i guese that would take some effort like bending the knees to reach down and put in a bag.

just one hour a day in the morning shore makes a diference.

And teaches some of the thai's a lesson in self respect as well.

More like a lesson in resentment, I'm afraid.

It would have to be Bass suicide...........

(s'ok, I know where the door is)

[katana]

There was a bit in thairath with pics.

Officials have tested the water and found it too alkaline at Ph 9. There's a nearby ice making factory using ammonia in the cooling process and they think this could be the source of the contamination. They expect to know within a week.

To turn a running stream to ph 9 is actually pretty difficult. Someone dumped a lot of stuff in there

It's been proven around the world that fines are a good cure for laziness. Here the remuneration is better at the traffic lights though for the boys.

[finnomick1]

Let's hope they clear up the pollution problem before releasing another 200,000 fish or they'll end up the same. Until the population learns not to abuse their surroundings, this type of ' disaster ' will continue to happen. For example, I took my grass cutting machine for repairs. The shop owner drained the old oil straight into the drain at the front of his shop -- incredible. And how many of the motorised food stalls throw their old cooking oil into the drains amazes me. How do you even start to educate people into doing the right thing ?

[Moruya]

On Monday they will ask the PM. She will refuse to answer.

[ratcatcher]

After 22 posts, I'd personally like to offer my condolences to the families of the fish that died in this tragedy.

I hope the B.I.B. or the appropriate department find the murderers quickly.

Definitely something fishy about this.

[PoodMaiDai]

Anyone want to place bets that a good number of those fish are going to be sold for food?

Yum, dinner at a restaruant near you.

Mass fish-death probe eyes wastewater pipes

The Nation

NAKHON RATCHASIMA: -- The mysterious death of over 100,000 fish in Nakhon Ratchasima province's Lam Taklong creek has prompted local environmental authorities to investigate the quality of water discharged from five suspected wastewater pipes and sewage-treatment systems.

Governor Chuan Sirinantporn yesterday instructed all related local authorities to investigate the fish deaths, including the Nakhon Ratchasima Municipality, Environ-ment Bureau Division 11, Nakhon Ratchasima Provincial Fisheries Office, Inland Fisheries Research and Development Centre, the Provincial Industrial Office, Provincial Public Health Office and the Suranaree University of Technology.

Nakhon Ratchasima Municipality Office and the Provincial Industrial Office also sent officials to collect samples and study water quality from a sewage treatment system and wastewater pipes inside factories located along Lam Ta Klong creek, particularly two ice factories near the Mall Department Store.

Results of the investigation are expected this week.

Chatphet Yosphon, of Suranaree University of Technology's Institute of Engineering, has visited the suspected area at Soi Sam Rong Chan to measure the level of oxygen in the water after the authority discharged water to flush waste from the creek.

He collected water samples from Khon Chum embankment behind The Mall Korat department store, Soi Sam Rong Chan, Wat Tha Ta Koh, and the VIP village.

His investigation showed the level of oxygen in water in all these five areas was lower than the standard.

At the VIP village it was only 1 milligram per litre, while at other areas it was 3mg per litre. He said most types of fish need 7mg per litre of oxygen in water to survive.

The result of his investigation will be released in the next three days.

Most Bangkok people just throw away their trash and it gets dumped into the other provinces...

[maidu]

The most expedient and easiest conclusion is 'inconclusive.' that's also the quickest way for Thais to forget this happened, and go on with things.

'Inconclusive' also avoids anyone losing face. In contrast, if they find a culprit, they might be compelled to prosecute, and that takes effort and time and added thinking. Easier to just hear the excuses, and say, "We think you may have done a bad thing. Please don't do it again." Plus, a wad of cash passed between two people is less hassle than determining a fine via the court system.
