Yet another mysterious mass fish die-off in North America - Temple, Texas

Temple Community Puzzled Over Dead Fish Pond


It's a mystery that has people in Central Texas scratching their heads.

Hundreds of fish turning up dead in a Temple pond this weekend.

When lifelong Temple angler Eloy Machuca came to Miller Park today he saw something he didn't expect.

"I come down here to release some fish, usually little ones so kids can catch them, but I've never seen this many," Machua said.

What he saw were dead catfish hundreds of them.

"I would say 90 percent of them are dead."

Florida: Indian River Lagoon mystery ailment killing dolphins, manatees, pelicans


The Indian River Lagoon on Florida's east coast has long been known as the most diverse ecosystem in North America.

Its 156 miles of water boast more than 600 species of fish and more than 300 kinds of birds.

The lagoon is not just an ecological treasure. To the towns along its edge - Titusville, Cocoa, Melbourne, Vero Beach and Stuart, among others - it accounts for hundreds of millions in revenue from angling, boating, bird-watching, tourism and other waterfront activities.

But these days the Indian River Lagoon has become known as a killing zone.

Algae blooms wiped out more than 47,000 acres of its sea grass beds, which one scientist compared to losing an entire rainforest in one fell swoop.

Then, beginning last summer, manatees began dying. As of last week, 111 manatees from Indian River Lagoon had died under mysterious circumstances. Soon pelicans and dolphins began showing up dead too - more than 300 pelicans and 46 dolphins so far.

Dead fish reported at Milford Reservoir, Salina, Kansas

Don Phillips and Larry Riat were both amazed and perplexed about a week ago when they fished at Milford Reservoir.

The amazing part included a massive run on channel catfish as they fished from a boat, using jig lures.

What alarmed and perplexed the 76-year-old retirees was the thousands of dead carp and other less desirable species in the water and on the shore.

"There were two dead carp about every foot. They were floating in the water about everywhere," said Riat, of Abilene.

The channel catfish were spawning, said Phillips, of Salina.

"We caught many, many of them and turned them back," he said. "They were good eatin' size."

The pair were after walleye and crappie. They caught a few crappie, but turned them back.

But what they wondered about most was the dead carp.

Why the dead carp?

Fisheries officials at the lake have been fielding reports about dead fish -- 99 percent of them carp -- for a couple of weeks, starting from the north end, said R.J. Harms, Milford operations manager for the U.S. Army Corps of Engineers.

Violent explosion shakes Mexico's Popcatepetl volcano

Mexico's active Popocatepetl volcano has registered a massive explosion spewing ash and incandescent rock almost 4 kilometers high. Authorities have warned that winds could blow the ash cloud as far away as Mexico City. Inhabitants of villages up to 25 kilometers from Popocatepetl (colloquially known as 'Don Popo') rushed out of their houses when the massive explosion reverberated through their homes. Esther Matinez, resident of Amecameca municipality, told Mexican publication La Jornada that the blast was like a rocket explosion. Around 4.5 million people live within a 50-kilometer radius of the active volcano, 650,000 of whom are considered to be at high risk.

Massive section of ocean floor off the coast of Portugal beginning to fracture

A new subduction zone forming off the coast of Portugal heralds the beginning of a cycle that will see the Atlantic Ocean close, as continental Europe moves closer to America. Published in Geology, new research led by Monash University geologists has detected the first evidence that a passive margin in the Atlantic Ocean is becoming active. Subduction zones, such as the one beginning near Iberia, are areas where one of the tectonic plates that cover Earth's surface dives beneath another plate into the mantle - the layer just below the crust. Lead author Dr João Duarte, from the School of Geosciences said the team mapped the ocean floor and found it was beginning to fracture, indicating tectonic activity around the apparently passive South West Iberia plate margin. "What we have detected is the very beginnings of an active margin - it's like an embryonic subduction zone," Dr Duarte said.

Strong 5.8 earthquake sways buildings in Mexico City

Image
A powerful two-punch earthquake shook western Mexico early Sunday, knocking out electricity and cellular phone service in parts of this sprawling capital. There were no immediate reports of serious damage or fatalities. Initial readings put the quake at a magnitude of 5.8 at around 12:30 a.m., with the epicenter about 90 miles south of Mexico City in the northern part of Guerrero state, where Acapulco is located. It was felt with marked strength in Mexico City, swaying major apartment buildings, hotels and skyscrapers. Residents scooted from their homes, some in pajamas, or filed out of late-night bars and restaurants. Many remained in the streets long after the quake ended, bracing for aftershocks. The shaking began gently, paused, then gave a good rattling to buildings in much of the capital.

Mexico City Mayor Miguel Angel Mancera, whose inspectors immediately took to flight in helicopters and fanned out through city streets, said there were no reports of serious damage but that several neighborhoods were without electricity. Interior Minister Miguel Angel Osorio Chong also said there were no reports of damage at the national level. Mexico is accustomed to such quakes, and a fairly strict system of checks and controls whips into place at the first sign of serious shaking. In 1985, parts of the Mexican capital were destroyed and at least 10,000 people were killed in a devastating quake. - LA Times

Editor's Note: County officials issued a correction to their news release on Thursday. The squirrels were found at Cedar Grove Campground and Doane Valley Campground.

Three squirrels with plague have been discovered at two campgrounds near Palomar Mountain.

San Diego County Department of Environmental Health officials urged hikers and campers to take simple precautions Wednesday to make sure they don't come into contact with squirrels or their fleas, which can spread plague, a disease caused by bacteria that can make people very sick and even kill them without quick treatment.

"It's not unusual for us to find plague in our area and there really are simple things people can do to protect themselves," said environmental health director Jack Miller. "The big thing is to avoid contact with squirrels and the fleas they carry. If you're camping, set your tents up away from squirrel burrows. If you're hiking, don't feed squirrels and don't let your kids play with them."

Torrential rains kill 73 in northern India, strands 73,000

Rains on Tuesday claimed 11 more lives in North India, taking the toll to 73, even as 71,440 pilgrims bound for the Himalayan shrines remained stranded in monsoon-ravaged Uttarakhand, apart from 1,700 people stuck in Himachal Pradesh. Though rescue efforts picked up in flash flood and landslide-hit areas of Himachal Pradesh and Uttarakhand with a let-up in the rains and decrease in water level in the Ganga and its tributaries, the whole of Uttarakhand still wore a marooned and devastated look. Hundreds of homes and roads were washed away.

Flash floods, cloudbursts and subsequent landslips in Uttarakhand have claimed 44 lives, left as many injured and destroyed 175 houses. Rudraprayag was the worst hit where 20 people perished and 73 buildings, including 40 hotels along the banks of the River Alaknanda, were swept away by the swirling waters. Pilgrims bound for Kedarnath, Badrinath, Gangotri and Yamunotri, are stranded in Rudraprayag, Chamoli and Uttarkashi districts with the 'Char Dham' yatra still suspended due to massive damage to the road network.

Mystery substance prompts closure of Indiana beach


  • Swimmers have been ordered out of Lake Michigan at Porter Beach because of a substance in the water. WBBM's Nancy Harty has more.

    It was originally thought to be an oil slick that prompted the closure of Porter Beach and the Indiana Dunes State Park Beach right next door, but park ranger Bruce Rowe says samples taken of the quarter-mile long slick show it is not.

    "The initial results, very initial, are that it is not oil based, but that we don't have the specific results as to what it is," Rowe says.
