Residents in Tavares are reporting hundreds of fish have been found dead in the canals of Lake Dora. The Florida Fish and Wildlife Commission said this likely is the result of the recent cold weather the area has experienced recently, and that the low temperatures pulled oxygen out of the water and caused the fish to die.
“Fish deaths resulting from exposure to cold have been reported statewide. Reports to the FWC Fish Kill Hotline and observations by FWC staff in the field indicate that a wide variety of freshwater and saltwater species have been affected by severe cold temperatures. We received water and fish samples and all indications pointed to cold weather-related deaths. As you know, these extended periods of unusually cold weather can kill fish outright by cold stress or make fish more susceptible to disease. Affected fish may appear lethargic and may be seen at the surface where the water may be warmer from the sun. In addition, we may be experiencing low dissolved oxygen issues at several areas due to the cloudy/rainy weather.”

The Secretary of environment (Seam) investigates the death of more than 1,000 kilograms of fish, found in the Paraguay River, in areas of the Department of Ñeembucú. Technicians carried out verification during the weekend.
The engineer Cristhian Ferrer, director of fisheries and aquaculture of the Seam, explained Monday that were making the denunciation of a new mortality of fish that occurred specifically in the areas of Villa Oliva and trench, of the Department of Ñeembucú.
When asked about the reason for the death of the fish, the official said that two scenarios are handled: one of them is the increasing of the water channel and the other is that the industries, both as the Paraguayan-Argentine side, could have made some kind of shock ACE.
“Was the greatest amount of dead fish in the Lakes, not on the Paraguay River, but after the winds and currents, fish were moving to the bed of the River,” Ferrer told Radio 1000 AM.
On the other hand, he cited that among the species that could be identified are surubí, from 20 to 30 kilos, gold, fish pacu, sea bass and other species of commercial value.
Ferrer remarked that in the course of the week you will have the results of the analyses are carried out, along with their peers Argentine, in order to determine the causes and reach those responsible for the death of one tonne of fish.

The coffee season is a bad omen for the inhabitants of the village Piñuelas, in the municipality of Santa Fe, Ocotepeque, in Honduras. On this site border with Guatemala and El Salvador, each beginning of year neighbors suffer from the massive death of fish and aquatic fauna of the Lempa River.
Edwin Padilla went on for a long time to fishing but by the deterioration of the Lempa River is now dedicated to agriculture. Padilla says that even farmers and ranchers cannot used this water because it is highly contaminated.
“We feel powerless and us is overwhelming, because we are producers and it is damaging the aquatic life in the River,” said the farmer.
The village Piñuelas in the past was a tourist site by the Lempa River basin, today does not to irrigate crops.

25 TONS of dead fish found on beaches in Rio Grande do Sul, Brazil
Hundreds of dead birds have washed up in Mount Maunganui and there have been more reports of dead poisonous pufferfish found along the Bay of Plenty coastline.
The Western Bay Wildlife Trust had received “mass” reports of shearwaters, petrels, prions, shags and penguins washed ashore and 38 pufferfish had been collected on Mount Main Beach.
Bay of Plenty Regional Council regulatory compliance team leader Chris Brewer said 18 pufferfish were collected between the Mount Maunganui Lifeguard Service and Leisure Island on Wednesday and another 20 were picked up between the Mount track and Shark Alley yesterday.
Brewer said the pufferfish had now been disposed of at the landfill.
The regional council’s senior environmental scientist, Stephen Parker, said the council had also received reports of porcupine fish washing up between Bowentown and Waihi Beach.
Parker said it was common for a range of wildlife to wash up on beaches after severe weather and where they washed up was usually determined by the direction of the storm or swell.
“The locations where these fish are washing up is where we would expect them to from the northerly weather patterns we are experiencing,” Parker said.
“We advise people and pets to keep as safe distance and not touch the fish as they have a neurotoxin in their skin and intestines.”
Tauranga marine ecologist Professor Chris Battershill said he had found about five porcupine fish every 200m along the beach halfway between the Mount and Papamoa which were all “on the small size for their species”.
Battershill said it was good the pufferfish had been taken off the beach. “MPI [Ministry of Primary Industries] are screening them for other toxins in case they have succumbed to something other than storms.”
Western Bay Wildlife Trust chairwoman Julia Graham said there had been a mass seabird mortality with many dead or dying birds being washed up on the beach.
“[There are] hundreds in the Mount alone but thousands up the coastline. I have been getting reports from Warkworth through to Whakatane of mass deaths of shearwaters, petrels, prions, shags, penguins and pufferfish,” she said.
“Many of these are juveniles that cannot survive in this rough weather and episodes of mass die-off are a natural course of events.”
Graham said the Western Bay Wildlife Trust and Arrc Wildlife Trust were handling exceptionally high volumes of birds needing care.
“Our volunteers work long hours and do everything that they can but we are extremely stretched and we need your help.”
Heidi Omundsen said she had found “tonnes” of spiked pufferfish along Bowentown beach and had warned a boy from picking one up.
“They were along the high tide mark, most of them were by the Bowentown headland,” she said.
Omundsen said she had phoned the council who told her staff had been dealing with numerous reports of pufferfish sightings along the region’s beaches.
“We are keeping our dog off the beach,” she said.
The Ministry of Primary Industries has also been contacted for comment.

Thousands of dead fish have mysteriously floated to the surface of a man-made lake at University Malaysia Sarawak (Unimas) for the past few days.
Efforts have since been carried out by lecturers from the university’s Aquatic Resource Science and Management Programme to identify the cause of the mass death of the fish.
One of the lecturers, Dr Aazani Mujahid, disclosed that the university received reports regarding the alarming number of dead fish – previously donated by the Inland Fisheries Department – last week.
Since then, she said more dead fish of various species were found floating on the surface of the lake.
“There are many factors that may have contributed to the death of the fish but we are still investigating at the moment,” she said when contacted yesterday.
She reckoned that one of the factors could be contamination by dirty water from nearby drains brought in by the rain.
Aazani regarded the dead fish phenomenon at the lake as nothing unusual as it had happened not only in the country but also overseas.
“The sudden change in weather can also make the fish die, particularly when our weather is rather unpredictable right now thus causing stress on the fish,” she opined. While the university is investigating the cause, Aazani advised those who come across dead fish at the lake not to take them or go fishing there.

ABOUT 250 fish were found dead at Mackay’s Gooseponds on Wednesday morning, the second report of a fish kill in just over a week.
Experts believe the fish suffocated as a perfect storm of conditions reduced oxygen levels in the water to a fatal concentration.
This is what killed about 100 fish early last week.
Catchment Solutions aquatic ecologist Trent Power said although about 250 fish had been cleaned up on Wednesday morning that was just a portion of the total fish killed.
He said more fish would have sunk after they died and he expects them to resurface over coming days.
Mr Power said the low oxygen level that most likely killed the fish was a result of three weather conditions.
Rain in October and November would have increased the nutrient run-off from rural and urban properties that algae and bacteria live off.
The still, calm days also would have increased the amount of algae and bacteria in the water, as a lack of wind and rain creates the stagnant environment they thrive on and direct sunlight helps them grow.
This algae and bacteria would have grown in volume and, despite producing oxygen during the day, through photosynthesis, would have heavily depleted the oxygen levels during the night.
It has been reported that some of the barramundi found dead were about 60cm long. Freshwater bony bream were also killed.

Hundreds of dead fish have been seen floating in a stretch of the Teesta in Jalpaiguri over the past two days.
A probe has been ordered amid suspicion that the water in the Mondalghat area along a 2km stretch of the river might have been poisoned.
As The Telegraph visited the spot, around 12km from Jalpaiguri town, on Tuesday, it was found that fish like “baim” (tire track eel), “taki” (spotted snakehead), “boal” (Wallago), “boroli” (Barred baril), “bata” (Bata) and some other species were either floating on the river’s surface or had washed up on the bank.
A section of locals were seen collecting the fish. “We have seen the dead fish since Monday morning and even on Tuesday. Some people here have collected around 45 to 50 kg of fish. We have no idea how it happened,” said Mintu Das, a fisherman residing at Gomostapara in Mondalghat, located close to the river.
Das and some other fishermen however, did not collect the fish. “We suspect some people have put insecticides or other poison in the water, which has left the fish dead. Common fishermen like us will be without our livelihoods because of such acts,” Jainul Haque, another fisherman, said, adding crabs too had floated up.
Ranjit Roy, a local resident, said some people had sold some of the dead fish. “The administration should see that those fish are not sold. It can lead to severe health hazards from poisoning.”
Earlier, in 2011 and 2015, similar incidents had occurred in Karala, a rivulet flowing through Jalpaiguri town and merging at the Teesta. It was learnt that insecticides were put in the river water to catch fish. Also, poison was mixed in the water of Teesta on December 2012, which had left several fish dead.
“When the Karala water got polluted, additional water had to be brought in from Teesta to purify it. It also took several months to restore ecological balance of the river,” a Jalpaiguri resident said.
As the news spread, officials of fisheries department reached the spot. They collected samples of dead fish and water.
“We will examine the samples to find out what has led to the (latest) incident. Our officers are also visiting the local markets to aware people and to see that such fish are not sold,” Ashish Saha, the deputy director of fisheries here, said.
They however, are yet to assess the quantity of fish which have died due to suspected poisoning.
The district administration has started an inquiry. “We are conducting an inquiry to find out why the river water got polluted. Those responsible will be identified,” said Rachna Bhagat, DM, Jalpaiguri.

He said, the incident was not the first time this reasonable note on Thursday (11/1). That time hundreds of fish that exist in the two indoor cultivation Senjoyo Village known dead and floating.
The next day, hundreds of other fish in the same pond were found dead. Unknown cause, he heard hundreds of fish in the pond, such as in the indoor cultivation of Sendang Putri was also found dead.
“To this day, if together the number of fish that die are already reaching thousands of tails. So that the total loss is also getting larger, reaching hundreds of millions of dollars, “he said.
Senjoyo Village pond Manager, Edi Siswanto (34) says, the kinds of fish that die this is a type of fish that had economic value. Among these types of koi, which also includes carps and Tilapia.
Even fish that die on average eight months old or has the size of four fingers to fish that are ready to sell. It also counted the amount of losses shared maintenance costs.
He also conveyed, the cause of death of thousands of fish are still very mysterious. So far for the freshwater fish farming in Senjoyo Village is utilizing water from the spring source Senjoyo.
Spring is also utilized as raw water for TAPS Salatiga city. But he did not want to prejudge if processing water triggers the death of thousands of fish in pond aquaculture. “Near here there are indeed the installation of processing clean water TAPS. It’s just that we do not want to conclude without supported with facts are accurate, “said Edi.
Even so, the group tours the Middle unconscious compiling reports so that these findings are acted upon by the related parties. “Moreover, the fish became one of the charms of the spring tourist Senjoyo,” he added.
Party TAPS Salatiga City confirmed denied if installation becomes a cause of death of thousands of freshwater aquaculture fish. Director of PDAM Salatiga city, Samino said, so far there are no complaints from the public to question the mysterious fish deaths.

People living near Colonial Manor Lake Park in the Miramar neighborhood near San Marco have noticed something disturbing in the water.
On Friday, hundreds of dead fish floated to the surface of the lake on San Jose Boulevard, which is also known as the “Duck Pond.”
“Usually, the pond looks healthy,” neighbors Jim and Marry Burch said. “(It’s) extremely alarming.”
The strange phenomenon has neighbors wondering what caused all of the fish to die, while ducks and other birds appear to be unharmed. Many asked whether it was the result of the weather.
““I’m disappointed, amazed and wonder why,” neighbor Dianne Scarboro said.
Air temperatures may have been warm Thursday and Friday, but the water stayed cold from the freeze earlier in the week. But according to a marine expert, it may have been more than just the cold water that killed the fish.
Dr. Quinton White, a professor of biology and marine science at Jacksonville University, told News4Jax on Monday that the cold weather at the beginning of last week did play a role in killing the fish, but added they didn’t exactly freeze to death.
“Because of the cold weather, even though it got warmer for a little while during the day, the water is still very cold,” White said. “When you get warm weather like that, we sometimes get what’s called ‘lake turnover.’ It brings up the oxygen-depleted water from the bottom to the surface, and that will kill the fish.”
Which means the fish likely died from oxygen deprivation, White said.
According to another marine biologist who lives close to the lake, the fish that died are not indigenous to the area, and were susceptible to shock as a result of the cold weather.
On Tuesday, News4Jax learned that crews had removed the dead fish.
