Hundreds of TONS of fish die off in fish cages in Lake Bato, Philippines

Fish Kill Alert

A two-week old fishkill has hit 70 percent of 18,770 tilapia fish cages in Lake Bato, affecting an estimated P52.5 million worth of tilapia stock, the Municipal Agriculture Office said Wednesday.

Alejandro Pili, agriculture officer, in an interview, said the fishkill, which started May 7, was triggered by a sudden downpour that pushed down the mass of decaying planktons to the bottom of the lake.

A fishcage has a minimum of 40 kilos to a maximum of 100 kilos of mature tilapia stock, according to Pili, but he could not give exact figures on the value of the losses since the fishkill started.

“Only three personnel are monitoring the fishkill,” said Pili.

The cost of affected tilapia stocks, however, could be estimated at P52.5 million considering the minimum of 40 kilos per fishcage affected, which could fetch a minimum price of P100 per kilo prevailing in the public market.

The 2,810-hectare Lake Bato is surrounded by three villages in Libon, Albay and 16 villages in Bato, Camarines Sur, based on information provided by Pili. There are 205 fish cage owners registered in the municipal agriculture office.

He said the cause of the fishkill was depletion of oxygen in the water as microorganisms caused the decay of planktons that were brought down to the bottom of the lake during the sudden downpour after a long searing hot weather.

Massive fish die off found in the Caspian Sea off the coast of Kazakhstan

Massive fish die-off at Caspian Sea

Eco Mangystau, a non-governmental agency, reported a mass fish die-off in Kazakhstan’s section of the Caspian sea, Tengrinews reports.

According to Lada the incident occurred in Karazhanbas region, 214 km away from Aktau in western Kazakhstan.

“A local resident reported that on the weekend he found several hundreds of dead fish floating on the surface and on the bottom of the sea. We filed a report to the environmental prosecutor’s office,” Kirill Osin of Eco Mangystau said.

The prosecutor’s office said that the die-off of fish in the sea was not connected to any production induced accident. “On the photos published in the media there are only dead carps. So the question arises why only carps died? It is more than likely that is has something to do with poachers activities, not some technology-related accident,” the prosecutor’s office said.

The Fish Inspection Department, Department of Ecology and local Sanitary and Epidemiology Station will investigate the causes for the massive die-off of fish in the Caspian Sea.

The prosecutor’s office has requested water, soil and fish corpses tests. The prosecutor’s office said that the results would be released after May 23rd.

Tens of Thousands of dead fish ‘mysteriously’ wash up in Marina Del Rey, California, America


Clean up efforts were considered over, but thousands of small dead fish remained in the waters off of Marina del Rey on Monday morning, two days after they were first discovered.

Scores of dead fish, believed to be mostly anchovies, began washing up in a corner of the marina near Bora Bora Way on Saturday night, creating a foul-smelling, silvery blanket on top of the water.

“It’s horrible. There’s like a million dead anchovies floating around, as well as other fish,” said Lisa Lascody, a resident of the area. “It’s creepy and weird.”

Crews spent Sunday cleaning up, and although carcasses continued to litter the water on Monday, a supervisor with the Los Angeles County Department of Beaches and Harbors said clean up efforts were over.

The supervisor estimated that about 3,000 to 4,000 fish carcasses were removed from the harbor.

The remaining dead fish floating in the water would either get eaten or eventually be pushed out into the ocean, the supervisor added.

It was unclear why exactly the dead fish washed up in the first place, but one marine expert speculates the amount of fish could have sucked the oxygen out of the water, and that could have caused them to die.

“The currents in here… it gets trapped in here, it doesn’t have a good flow. So it’s possible all these anchovies came in here, then all the other fish came in here, and all of that massive load of anchovies…sucked out all of the oxygen in the water. And through that, everything died,” said Eric Martin, the facility director and educational co-director of Roundhouse Aquarium, a marine studies lab in Manhattan Beach that teaches about the ocean and marine life.

The was not the first time numerous dead fish showed up dead in Southern California waters. In March 2011, millions of small fish turned up dead in King Harbor in Redondo Beach, according to the Los Angeles Times.

In that incident, it was believed that the fish used up all the oxygen after swimming into the marine en masse and eventually suffocated, the Times reported.

Thousands of sheep dead after ‘bashing their own heads on rocks’ in NSW, Australia

Thousands of sheep in Australia are believed to have died after eating a poisonous plant that makes them “bash their heads on posts and rocks until they crack open”.

The usually-rare toxic plant, misleadingly named the “Darling pea”, has spread rapidly in the aftermath of bushfires in New South Wales – which themselves caused devastation for sheep farmers in the area.

Now vets have said that many of the animals which survived the fires face a new and highly addictive threat.



North West Local Land Services regional veterinarian Bob McKinnon told the Sydney Morning Herald that once sheep started eating the plant they exhibit behaviour “similar to that of a drunk”.

“They lose weight to start with and then get staggery, the progression gets worse, they get unco-ordinated and depressed, they don’t know where their feet are.”

He said that “staring eyes”, “head pressing” and “muscle tremors” were other symptoms, until eventually the animals “just go to a post and bang their head on it till they crack their heads open”.

The task of bringing in herds that would normally take six hours instead takes “days”, Mr McKinnon said. “It’s like dealing with a thousand heroin addicts.”

Just one farming family in Coonabarabran said they had lost 800 sheep to the deadly plant. Stephen and Louise Knight said the animals were missing when they counted up the stock at shearing time.

“It was just devastating they weren’t there when we went to get them.

“The fire was a distressing thing to have happen, we lost so many stock, fences, pasture – and then for it to come back with a terrible noxious plant like this, it’s awful and very distressing.”

The plant, from the Swainsona family of desert peas native to Australia, has toxins which build up when sheep graze on it for extended periods. It attacks an enzyme involved in metabolism, ultimately crippling the animal’s central nervous system.

There is no cure, Mr McKinnon said, other than to “get the animals off it in time”. “But if they’ve been on it too long the damage has been done and it doesn’t repair to where it should be,” he said.

Mass deaths of birds found washed up on Humboldt National Reserve in Chile

Masses of fish turn up dead in a Marina in Pultneyville, New York, America

Fish Kill Alert

The Pultneyville Yacht Club was inundated with dead fish and plump, happy seagulls last week leaving local boaters with questions. Why all the dead and dying fish and just how many seagulls can fit in to one square foot?

Yacht Club members and customers of the adjacent Landing at Pultneyville became victims of sudden bird flights and accompanying cars also felt the brunt of bird droppings.

Jim Deatsch, member and Environmental Officer for the Yacht Club said he noticed struggling and dying fish cropping up about 10 days ago. “The gulls were having a field day. I even saw a couple of turkey buzzards come by, but they were chased off by the seagulls,” said Deatsch. “This is not a good thing. The gulls won’t eat the dead ones,” he added.

Yacht Club member Don Bernese of Walworth said he noticed the tens of thousands of dead fish and accompanying seagulls last Wednesday. The main channel of the Yacht Club remained clear, but the offshoot dock areas remained cluttered with dead and dying fish.

The small fish, known as alewives, often exhibit seasonal die-offs and can be seen, usually in mid-May, washed up on the shorelines of the Great Lakes. Alewives were introduced to the Great Lakes as food fish for the species such as lake trout and the introduced Pacific salmon.

Ironically, the DEC (Department of Conservation) had poured thousands of 4” to 6” brown trout off the Pultneyville Point a week before.

Was this a case of nature taking its course and an alewives die-off, or was there something amiss with the fish? Why did the fish die just in the Pultneyville channel and nowhere else along the shoreline in either direction?

The DEC was not taking any chances. On Tuesday (5/13) the DEC took samples of the dead fish and sent them to Cornell for testing. Some on the scene believed it could be viral hemorrhagic septicemia, a deadly infectious fish disease that afflicts over 50 species of freshwater and marine fish in several parts of the northern hemisphere.

Webster (Web) Pearsall, the Regional Fishery Manager for the DEC out of the Avon Office, was leaning more to the natural cause of the fish die-off. “This is part of a normal cycle.” The cold winter and warm waters feeding the lake cause a sudden rift in water temperatures that the alewives simply cannot tolerate. He noted that since the fish die-off in the Pultneyville channel, similar reports are now coming in from other Lake Ontario feeds, including the Genesee River outlet. “It is an issue of thermal shock on the fish,” concluded Pearsall. He added that the fish scoop-up and samples sent to Cornell was just to confirm what he believed. Sodus Town Supervisor and longtime boat captain, Steve Leroy, said he has seen this type of fish kill numerous times in his boating career. “I could be wrong, but I believe they will find no contaminants in the fish.”
