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.

600 animals dead due to flooding in Afghanistan
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.

From March until May 8, the bodies of thirteen dead dolphins arrived on the coast of Cantabria and beached on their beaches. At the same time, a rorqual was found alive on the Santander beach of Bikini and a seal on Ajo, which were returned to their natural environment.
They are data offered in the plenary session of the Parliament by the Minister of Rural Affairs, Fisheries and Food, Jesus Oria, when questioned by Podemos and on whether the result of the necropsies carried out by the general direction indicate that his death could be caused by fishing accidental in pelagic trawlers.
To this question, the counselor has indicated that only a necropsy can be performed when the mammal’s body is still in good condition and when its length does not exceed four meters. In the case of the 13 bodies of dolphins found since March, it has been possible to perform a necropsy on four of them and the information on three of them is already available.
In at least two of them, the counselor has acknowledged, the bodies show injuries that show that the death was caused by “entrapment in networks”. One is located on the beach of Galizano and another in the Bocal de Santander, and both had a broken jaw, a lesion characteristic of mammals that die after being caught in networks of fishing boats.
Oria has detailed that Cantabria has a network of tracking of strandings since 2010, and since then a total of 204 marine mammals have been beached on our beaches , which are taken care of by the Medio Medio kindergarten. This, he explained, he transferred to the Wildlife Recovery Center of Villaescusa to perform the necropsy if possible and, if not, the body is cremated in the center of Meruelo or buried in its environment in case that the Maritime Museum of the Bay of Biscay requests the skeleton.
