After Kannauj, thousands of dead fish were found floating in Ganga at Bilhaur’s Nanamau ghat, Chaubeypur’s Andimata and Pathakpur ghats in Kanpur on Tuesday.
District and Pollution Control Board officials rushed to the site and collected water samples for examination. A large number of fish had died in Kannauj’s Mehndi ghat on Monday.
Panic gripped residents of Bilhaur, Chaubeypur, Bithoor, Bhairav ghat, Shuklaganj, Gola ghat and Jajmau areas after thousands of dead fish were found floating in Ganga on Tuesday. Though the exact cause of their death is yet to be ascertained, officials of Regional Pollution Control Board said that they died due to heavy pollution which has reduced oxygen level in water to 2.8 mg.
A team of Wild Life Institute of India (Dehradun) and pollution control department visited Kannauj and collected water samples and dead fish for tests.
A team member said that it was primarily found that lack of oxygen level in water had caused death of the fish.

It’s fish kill season in Minnesota (and yes, that is different than fishing).
All around the state, hundreds of dead fish are washing up to the shorelines of small lakes, including about 10 lakes in the east metro. But officials aren’t concerned.
Winter kill is standard, especially in longer winters like this year’s.
“It’s a natural process,” said Jim Levitt, a fishery specialist for the Minnesota Department of Natural Resources. “It can actually benefit the lake in that the fish that are left have less competition. There’s more food for them, they might have a growth spurt, and there will be bigger fish for the next year or two.”
Lakes have a certain amount of oxygen in them when they freeze in the fall or early winter. The fish use that oxygen all winter and into the spring. In bigger lakes, there’s enough oxygen for most of the fish to survive, but in some of the smaller lakes, the fish slowly start to die as the oxygen depletes.
Quick lake warm-ups can also cause bacterial infections, which kill the fish as well.
“Spring can be stressful on fish,” Levitt said. “They’ve gone all winter maybe not feeding as much, it’s been cold, and now the water all of the sudden warms up and it’s spawning season so they’re spending a lot of energy on that.”
As a result, most of the fish kill calls come within a month of ice-out.
Sometimes, thousands of fish will die from winter kill, but even those high numbers are not cause for alarm, Levitt said. Although the DNR doesn’t have exact numbers of fish in each lake, several thousand fish might still be less than 10 percent, he said.

The high temperatures that in recent days have reached thermal sensations of up to 40 degrees, coupled with the decrease in the levels of the lagoons El Jahuacte, Trujillo, Barra Ciega and El Jitalito, in the area of Los Aztlanes, caused the mortality of more than 200 tons of fish during the weekend; producers urge the activation of an emerging fund for 1,500 fishermen.
Sergio Arias Isidro, president of the Board of Administration of the Federation of Fisheries Cooperatives, Aquaculture and Permits of Tabasco, said that on Saturday, May 12, the lagoons were covered by the stain of dead fish.

Concerns are growing for the future of the country’s best known carp fishing lake after most of its stock was wiped out by an unknown infection over the past couple of days.
Over 400 dead carp – many up to 20 years old – have been removed by Inland Fisheries Ireland from The Lough, an urban lake in Cork city, since Saturday.
Samples have been sent to the Marine Institute in Galway for testing.
A bacterial or fungal infection is suspected, but after tests on sample fish the highly-contagious Koi Herpes Virus (KHV) has been ruled out.
Further testing is continuing, but the cause of the deaths will not be known until later this week.

A fish kill has affected about 100 hectares of fishponds in Obando, Bulacan.
Wilfredo Cruz, regional director of the Bureau of Fisheries and Aquatic Resources (BFAR) for Central Luzon, said the fish die-off started manifesting last Saturday right after an earthquake was felt in the area.
Cruz surmised the earthquake could have released ammonia gas from the ground into the fishponds and suffocated the fish with depletion of oxygen.
A BFAR team has been sent to the area to assess the situation and come up with assistance to affected fishpond operators, Cruz added.
He said they recommend that the dead fishes be buried at least 1-meter deep in the ground to prevent them from spreading diseases caused by decaying body parts.
On the other hand, Raul Agustin of the provincial disaster risk reduction management office of Bulacan, said fish kill is a natural occurrence whenever earthquakes occur because the water quality of the fishponds are being altered by the earth’s movement.
Fishpond operators also noted that fish kill occurs whenever there is a sudden, heavy downpour during the summer months and jeopardizing the water quality of the fishpond.
The fish kill has already caused foul odor affecting several barangays of Obando, some residents said.
