(CNN) — The unexplained beachings of scores of dolphins over the past month along Cape Cod, Massachusetts, is the largest “single-species event” of its kind on record in the northeastern United States, a marine mammal specialist said Monday.
A total of 129 common dolphins have been found since the animals began stranding themselves in early January, said Katie Moore, marine mammal rescue and research manager for the International Fund for Animal Welfare.

Pattern Recognition - Mass Fish Kill Roundup - Early May 2011

This just doesn’t stop. I’m past the point of thinking these numbers are “normal” or that they “happen all the time”.  The effects of poisoning, oil spills, climate change in the form of extreme winter conditions, and algal blooms also caused by humans cause this trend to continue.

Fish and Wildlife Services say that the remaining fish should do well because there will be less competition. “There will be lots of food for them, and they’ll start reproducing as long as we don’t get a number of winter kills. Then they’ll come back on their own,” says Ed Pirogowicz, Fish and Wildlife Officer.

Mystery over death of whale in double stranding - New Zealand - March 5th, 2011 (yeah, I missed this one so it’s late) - cause of death unknown

A blue whale stranded on the Waiinu Beach over the weekend is the first of its kind to be seen on the South Taranaki coastline in 30 years.

Anton van Helden, collection manager of marine mammals at Te Papa, said that, from the pictures he saw, it was incredibly emaciated, which was odd for this time of year.

"It’s quite an unusual occurrence for us to have a baleen type whale," he said. Baleen or whalebone whales were krill feeders who lived in deep ocean areas Mr Campbell said.

Other deep sea whales have been spotted in rare close to shore sightings this year.

Gray and Blue whale migrations patterns deviate this year - Southern California - May 1st 2011 

This final stage of the northbound migration through Southland waters is occurring later than usual and comes during an unseasonably early arrival of blue whales into Southern California waters.

Blue whales are being seen sporadically, as close as a mile from shore to several miles offshore, as they presumably conduct a hunt for vast blooms of shrimp-like krill. The Dana Pride crew has seen krill off Orange County and on Saturday the crew of the Christopher out of Long Beach witnessed a blue whale lunge-feeding at the surface, nine miles from shore.

Lemming hordes on pace for record migration in Sweden - April 11, 2011

Hordes of lemmings have been spotted leaving the safety of the mountains to make their way down to more inhabited areas, falling victim to traffic and being preyed upon by other animals.

“I must have seen a thousand just since Saturday. They are absolutely everywhere. They are swimming about in the lake close to our house, they jump on the ice floes, and they scurry around the outside of our house,“ said holiday-maker Magnus Lundberg, to the local Östersundsposten (ÖP) daily.

Favourable weather has created the conditions for 2011 to become what Swedes call “a real lemming year”.

According to Bengt Landström of the mountain unit at the County Administrative Board in Norrbotten, this may well be a record year for lemmings…

Record wildlife die-offs reported in Northern Rockies

A record number of big-game animals perished this winter in parts of Montana, Idaho and Wyoming from a harsh season of unusually heavy snows and sustained cold in the Northern Rockies, state wildlife managers say.

Based on aerial surveys of big-game herds and signals from radio-collared animals, experts are documenting high mortality among offspring of mule deer, white-tailed deer and pronghorn antelope.

Wildlife managers estimate die-offs in the tens of thousands across thousands of square miles that span prairie in northeastern Montana, the upper Snake River basin in Idaho near Yellowstone National Park and the high country of northwestern Wyoming near the exclusive resort of Jackson.

Brimeyer said the estimated death rate doubled among deer fawns in the Jackson area this year, rising to 60 percent or more from 30 percent.

He said many thousands more elk have crowded the feeding grounds of the National Elk Refuge near Jackson, yet another sign of the toll winter is exacting. The trend also is pronounced in a wildlife management area near McCall in the mountains of central Idaho, where the estimated mortality rate among mule deer fawns is 90 percent this winter, compared with an average annual rate of 20 percent.


"Uncommon" death of 15 sharks in Florida

Recently more than a dozen dead sharks were found on the north ends of Longboat Key and Anna Maria Island. “There were no real indicators of what went wrong with them,” Dr. Nick Whitney, Staff Scientist for the Center for Shark Research at MOTE Marine Laboratory said. “There are no obvious signs of damage from fishing or net damage or anything like that.”

Whitney said he’s ruled out the possibility that the sharks died as a result of last year’s oil spill.

"Oil spill is pretty unlikely because these animals tend to be coastal," said Whitney. "They move up and down coast, but they wouldn’t tend to go off shore and in deep water where oil is."

For now, Whitney says what happened to these sharks remains a mystery.

Researchers have sent samples from the sharks to a different lab to try and see if red tide killed them.

However, they say this is highly unlikely since they have not detected any red tide in the area.

MOTE researchers say finding a dead shark now and then is not rare, but it is uncommon to find a group of them dead within a few days.   Source


Pattern Recognition - Fish & sea animal deaths April 2011

When I compile these lists of fish kills, I find myself saying the same thing. Yes, I know it’s something that has happened before. I know the ready availability of information on the internet makes the stories more accessible and they get reported more because news outlets know it brings in readers and viewers.

What concerns me is the regularity of eye-witness and expert descriptions using phrases like "record setting", "inexplicable",  and “unprecedented" or, "I’ve been here for 28 years and I’ve never seen anything like it.” or “I haven’t seen this density before,”, or “We have never seen anything like that” in the 17 years [we’ve lived here]”.

The experts say the Harmful Algal Blooms are poisoning them, or that they have too little oxygen because it is too warm or too cold.

We know that they are often dying in mass numbers because humans poison them with sewage, chemicals, and oil.

If you believe that this is a sign of the end of the world, feel free, but I take it as a sign that we are “shitting where we live”, if you’ll pardon my crudeness. 

Personally, I think climate change is related to many of the oxygen deprivation cases. Whatever the cause, aberrant weather patterns on a global scale combined with pollution has increased the volume of animals and fish affected.

So, I’ll keep tracking this because it interests me, because it’s shocking, and because it’s yet another sign of the changes our world is going through. If you think you can keep living here and not be affected, think again. Next time the fish might be rotting in YOUR backyard.

Dead Fish round-up - 03/30/2011

Experts say that these are all due to winter conditions and oxygen deprivation. Other folks who live near the fish kills will say they have never seen it like this before. We had some severe winter weather this year. Not a sign of the end of the world, but in my mind, definitely a sign of climate change.  And then there are the ones from pollution and oil spills….

Small fish kill in Bangladore

Oxygen deprivation again…

About 150 fish were found dead at a pond in JP Park of Mathikere on Tuesday night. Bruhat Bangalore Mahanagara Palike (BBMP) officials said that the fish were choked to death owing to excessive evaporation of water in the stagnant water body.


Another small kill in a pond in Missoula

A line of dead fish -- those white dots -- stretch across part of the pond

Visitors to the duck pond on the south side of town will find a pretty gross scene: more dead fish than actual ducks.

Roughly 50 dead fish are visibly floating on the surface of the small pond. Neighbors first noticed the issue and reported it to Missoula Parks and Rec yesterday. This morning, Parks and Rec recovered one of the fish and sent it to Fish, Wildlife and Parks for testing.


Small Fish Kill in Minnesota

ALEXANDRIA, Minn. (KSAX) - Around 300 dead fish were found in Lake Agnes and Lake Henry earlier this month in open water areas after ice had melted. But both residents and experts said they’re not sure why.

"All winter long, I’ve been fishing the lake (Henry), and I ran into a situation where we had a four to six foot column of fish, and all of the sudden, they disappeared. I could not find a fish on the lake," Lake Henry resident and fisherman Rick Colden said.  

Colden isn’t the only one who’s had a hard time on the lakes, as more than 2,000 anglers failed to catch a fish at a tournament on the adjoining Lake Agnes on Feb. 12.

But the recent evidence of fish kill may be to blame.

"A lot of game fishes; walleye, bass, bluegill, some crappie, (were found dead). So certainly a concern," Minnesota Department of Natural Resources area fisheries supervisor Dean Beck said.

Beck said it’s hard to pinpoint a timeframe or reason for the fish kill because both fish and water samples can no longer provide accurate readings.


Small fish kill in Connecticut

Wallingford, Conn (WTNH) - It’s happening in a lot of fresh water around Connecticut right now. Dozens of dead fish are turning up, floating on the surface. The DEP says it’s a common occurrence after the kind of winter we had.

North Farms Reservoir in Wallingford is very large, but it is also very shallow. It’s just six feet deep at most, and that may be a factor in what’s happening.

It is a peaceful spot off Route 68 in Wallingford. Lots of swans and ducks paddle around with no particular concerns, but it didn’t take long for our cameras to find dead fish including big bass and tiny sunfish.

It was worse just a few days ago. Photos were sent to us by Nick Santillo, who found dozens of dead fish piled up in the reservoir.


Smaller kill in west Texas

With nets in hand, city staff were continuing Monday to remove dead fish from Wadley Barron Park after a pond ‘turnover’ that created a lack of oxygen for the organisms living inside.

Parks & Recreation Manager Scott Swigert said they were alerted Thursday fish were dying and have been working on the issue each day since, having seen a decrease in the rate at which fish were dying by Monday.

"We are currently experiencing what’s known as a pond turnover," Swigert said, explaining why hundreds of fish have died. "It’s a naturally occurring event … It’s happened in the past and we’re confident it will occur again in the future."

When sediments build up at the bottom of a pond, the water eventually will flip, causing the oxygen on the top of the water to mix with the carbon dioxide and other chemicals at the bottom, creating a lack of air.


1000’s of dead fish and a few turtles and gulls on Misery Bay on March 22nd 

Cathy Pedlar and Kathryn Hamilton were walking by Presque Isle State Park’s Misery Bay on Tuesday afternoon when they spotted thousands of dead fish along the north shore.

Pedlar said she’s seen dead fish before, but never like this.

"I haven’t seen this density before," she said.

Park and state officials were notified and a Pennsylvania Department of Environmental Protection official investigated.

"This is a natural fish kill, no cause for alarm," Jim Grazio, a Great Lakes biologist with DEP’s Office of the Great Lakes, said after inspecting the dead fish.

He said 99 percent were gizzard shad and he believed their death was a natural event caused by temperature change.

Grazio said the gizzard shad, a freshwater herring, is notoriously sensitive to cold temperatures and temperature changes.

He also said more than the usual number of the fish were born in 2010 for unknown reasons.


Thousands of Dead fish in Michigan blamed on cold

Michigan officials say thousands of dead fish found in the Lake St. Clair area likely died because of the cold weather.

The state Department of Natural Resources and Environment says Friday that large numbers of gizzard shad probably died because of the lengthy, cold winter. State officials say they’ve collected samples and had them analyzed, and they don’t suspect a fish virus or bacterial disease is to blame.

Thousands of dead gizzard shad were found earlier this year in Lakes Erie and St. Clair, the St. Clair River and the Detroit River. Shad deaths are typical in the winter.


Winter fish kills on numerous lakes in Iowa

The Iowa Department of Natural Resources has received numerous reports of dead fish in lakes and ponds across Iowa as the ice cover disappears for another year. 

These winter fish kills have been reported at Swan Lake (Carroll), Badger Creek Lake (Madison), Clark Lake (Cerro Gordo), Kuhn Wildlife Pond (Cerro Gordo), Pilot Knob Pond (Winnebago), Alice Wyth Lake (Black Hawk), Middle Sabula and Green Island lakes (Jackson), Credit Island Lagoon (Scott), and a storm water retention pond in Guttenberg.


Number of dead whales and dolphins in the Gulf at least 50 times higher

Many more dolphins are dying in the Gulf than are officially counted. New research released today shows that the average number for most species is at least 50 times higher than what’s reported now, a conservative figure according to the authors.


The death toll of animals that perished as a result of the Deepwater Horizon/BP oil spill in the Gulf of Mexico may be 50 times higher than presently believed, according to a new study in the latest issue of Conservation Letters.

Until now, fatality figures have primarily been based on the number of recovered carcasses. Data on this varies depending on the source and the date of the count, but the authors report that as of Nov. 7, 2010, 101 whale, dolphin, and porpoise carcasses had been detected across the Northern Gulf of Mexico.

Past numbers of carcasses reflect just 2 percent of actual animal deaths, according to the study, so the true number of fatalities for cetaceans alone as a result of the spill could be in the thousands.


15-20 dead gulls monthly at San Fran pier - mold to blame

Earlier this month The Bay Citizen published a story about the alarming number of western gulls that are dying near San Francisco’s industrial Pier 94. The article, “Mold Mystery Surrounds SF Bird Deaths”, states a preliminary investigation by the California Department of Fish and Game may have found the cause.

According to the article, “The department found 15 to 20 dead or dying gulls monthly, according to California Fish and Game Warden William O’Brien. It performed autopsies on a number of dead gulls and found that growing inside their lungs was a mold called Aspergillus, which suffocated the birds.”



Six porpoises wash up dead on Mass. shores - week of 03/21-27/2011

ix juvenile harbor porpoises have washed up dead on Massachusetts beaches this past week, according to officials at the New England Aquarium.

The most recent one was a 4-foot-long, dark gray harbor porpoise found Saturday morning on Revere Beach. The New England Aquarium’s Marine Animal Rescue Team responded, but the animal was already dead.

Tony LaCasse, spokesman for the New England Aquarium, said this number is “exceptional” for one week but it is not uncommon this time of year for young porpoises to die after being stranded on shore.

“We are seeing a high number but these animals appear to be passing away from what are the normal causes of death,” he said.
