The Iowa Department of Natural Resources is investigating hundreds dead fish on two-mile stretch of lower Walnut Creek near a popular Des Moines bike trail.
DNR spokesman Anthony Bigger said they estimate 500 to 600 dead fish are in the creek, though he said there could be as many as 1,000. Several people reported dead fish along 63rd Street, a third of a mile south of Interstate Highway 235.
The section with fish kill runs along the Walnut Creek Bike Trail, which led to a high number of reports, according to a DNR news release.
Bigger said the cause is still unknown as the DNR continues their investigation. He said the potential causes include somebody dumping chemicals down their drain, temperature and water main breaks.

A massive fish kill-off in Shipshewana Lake was caused by a natural phenomenon.
The Indiana DNR says this is typical during extreme heat. The temperatures cause an algae bloom, which depletes oxygen from the water.
That causes a fish kill.

State wildlife experts are investigating a large fish kill at Myrtle Grove. Thousands of dead pogies, catfish and crab surfaced at the canal, and the boat launch all day, just days after Hurricane Barry’s storm surge moved out.
First it was Barry and the floods that followed. Now fishermen in this prime area are having to deal with a smelly large fish kill at a popular boat launch.
Pearl Young, who has fished the Myrtle Grove marina for years, said she didn’t like what she saw today, or smelled.
She fished right off the dock and had little luck, while others went farther out to find clean water.
The fish kill comes just days after Hurricane Barry pushed storm surge into this area. Huge sandbags used to shore up the levee are visible from the launch and many say it’s not unusual to see dead fish like this after tropical weather.
Thousands of pungent-smelling dead fish were visible hundreds of yards from the launch, but fishermen went out anyway to try their luck and checked their spots.
The fish kill created a feeding frenzy for seagulls.

The hundreds of dead fish removed from a neighborhood pond Wednesday in Lombard were an alarming sight, but Mother Nature likely played a role in their demise.
The fish apparently died as a result of oxygen deprivation related to the scorching heat and shallow depths of the Lombard Lagoon, park district officials say.
A neighbor of the pond at Grace Street and Marcus Drive reported the dying fish shortly about noon Tuesday, interim Parks Superintendent Dean Styburski said. The park district responded with the full weight of his department, assembling 24 employees for the cleanup effort.
By Wednesday afternoon, as air temperatures hovered around 90 degrees, some 400 to 500 carcasses from the so-called “fish kill” had been cleared from the pond, Styburski said.
Aquatic management consultants advised the park district Wednesday that the worst of it is seemingly over, though there still may be additional deaths, Styburski said.
Consultants from Crystal Lake-based Environmental Aquatic Management LLC suspect that warming waters depleted the pond of the oxygen necessary for fish to survive. Which is why Styburski was crossing his fingers for rain and wind to stir up waves and help oxygenate the Lombard Lagoon, a 4.35-acre pond no deeper than 6 feet and fed by stormwater.

The re-occurring sulfur bursts in Lake Batur, Kintamani, have impacted the deaths of thousands of fishes cultivated by farmers in floating nets (KJA). Fish farmers also lose up to tens of millions rupiah.
The most severe areas are affected by sulfur bursts, namely Banjar Seked, Batur Tengah village. The phenomenon of sulfur bursts causes fish to die sporadically. I Ketut Wania, a fish farmer in Banjar Seked, the most enduring loss due to sulfur burst phenomenon. About 2.5 tons more of his fish are ready to harvest, die.
Encountered Monday (15/7), Wania revealed, a burst of sulfur in Lake Batur knew it began to emerge since early Sunday. The sulfur bursts cause many dead fish. A mass fish death in KJA was known Monday morning when checking into the hospitality. “The many dead fish that are ready to harvest ages 7-8 months. From 34 KJA holes, which are ready to harvest there are two holes. Each hole contains 4-5 thousand tails, “he explained.
While the fish that are under the age of 4 months can still survive. According to him, fish whose age is still more strong to endure when the sulfur bursts occur, because it is more often on the surface of the lake.
Due to the sulfur burst phenomenon, he now has to bear losses of up to Rp 70 million. To minimize the death of other fish, he was forced to stop activities in KJA including not feeding the fish during sulfur bursts. “Because when we approach the Keramba, fish will descend to the bottom of the lake, and it causes fish to lack oxygen,” said Wania.
According to him, this burst of sulfur is a natural phenomenon that occurs every year. Two years ago, the sulfur bursts in lake Batur were quite severe, but in Banjar Seked area it is safe from the impacts of sulfur.

In the past few days, the large yellow croakers in many places in Ningde, Fujian Province have died bizarrely. Many farmers have suffered heavy losses. Videos and pictures have spread throughout the circle of friends of Ningde people! The densely packed large yellow croaker body floats on the sea, and the scene is shocking!
It’s a pity that the fish are dead and the farmers’ hearts are broken!
Organize experts to go to the four coastal counties to understand the situation and do a good job of “white spot disease” prevention work! Strictly prevent sick and dead fish from entering the market!
The pathogen of “white spot disease” is to stimulate the hidden nucleus, which has a fast infection rate and a high mortality rate!
Large yellow croaker, also known as yellow croaker, cucumber fish, and golden dragon, is a favorite seafood of Taizhou people.
Recently, however, Ningde marine aquaculture has entered a period of high incidence of “white spot disease”, and some large-scale yellow croaker farming has caused “white spot disease”, causing different degrees of loss to fishermen!
The pathogen of “white spot disease” is a common parasitic disease, which occurs in spring and autumn. The water temperature is 20 °C to 26 °C, the water flow is not smooth, and the water environment is not good. High, fast infection, high mortality, “white spot disease” is serious, the fish body surface is covered with small white spots, forming a turbid white film, the damage of the fish gill tissue is in a state of stress, so far no specific drugs Take control.
Then the question is coming. What caused the massive death of fish?
The weather is changeable, sultry, heavy rain, resulting in the stimulation of the proliferation of hidden nuclear worms, a large number of cages distributed, resulting in lack of oxygen in the fish, speeding up the death of farmed fish!

Norton Sound residents have reported salmon die-offs in unusually large numbers during the last week.
According to the Norton Sound Economic Development Corp., dead pre-spawned pink salmon were found in multiple river systems last weekend.
The corporation’s fisheries director, Wes Jones, says the numbers of dead humpies being reported are larger than what’s normally seen in the Norton Sound region, spread out across several communities from east to west.
“There’s been reports all the way from here (Unalakleet) in Eastern Norton Sound all the way over to the Nome area. And it’s a very widespread area. The big change is that it appears that it is a much bigger event happening in eastern Norton Sound than what you’re seeing as you get closer to the Nome area.”
One of those reports came from Sophia Katchatag, the community coordinator for the Native Village of Shaktoolik. On Tuesday evening, Katchatag took her family up the Shaktoolik River, to a place called Jink-wok, to swim and cool off from the hot weather. She found a creek with “one area completely filled with dead pinks floating on top of the river.”
Katchatag didn’t pick any of them up, and she doesn’t intend to eat them, either.

Staff of the National Coordinator for Disaster Reduction (Conred) came to verify the death of thousands of fish of various species, which appeared this Saturday on the shore of Tecojate Beach and the Zanjón Salado River in Nueva Concepción, Escuintla.
According to local media, the neighbors blame the death of these animals on several shrimp companies that operate in the sector and expel their waste to the rivers, as well as the drains that flow into the beach, producing high levels of pollution.
