Scientists in Uganda are investigating the cause of death of hundreds of fish washed up on the shores of Lake Victoria.
Joyce Nyeko, acting director of fisheries at the ministry of agriculture told Xinhua by telephone on Sunday that preliminary investigations have ruled out fish poisoning by fishermen.
Nyeko said there is a likelihood that the death is caused by recent flooding, water hyacinth weeds, some of which sank and during the rotting process, oxygen in the water was used up.
She also noted that with the recent strong winds, there has been lake overturn with bottom water that has low-level oxygen spring up and mixing with the upper layers and therefore reducing oxygen levels and thus killing fish.
Nyeko said the ministry is investigating whether similar deaths have occurred on the shores of other lakes and rivers in the country.
Local media reported that dead fish washed up on the shores of Lake Victoria in Entebbe, 40 km south of the capital Kampala.
The official advised people living near the lake to pick the dead fish and bury it to reduce the smell.

15,000 fish died on Sunday in a pond of the Viechtachfishing club. That’s the entire stocking of the water, police say.
A clogged junction is therefore considered to be the cause. From this the water of the Hofbach was directed into the ponds of the association. According to initial findings, this may have been caused by nearby forestry work as part of the expansion of the Bundesstraße 85.
Investigations have been launched by the Viechtach Police Inspectorate to establish the cause. Water samples were taken and some of the degenerated fish were seized. The water management office and the Regen district office were also involved in the investigation.
According to preliminary estimates, the damage amounts to at least 15,000 euros.

On Friday (8/1/2021), thousands of dead tandeman fish were stranded on the edge of Sikabaluan Beach, North Siberut District, Mentawai Islands Regency.
The phenomenon that shocked local residents was known to the public after being uploaded by a Facebook social media account user named Nova Sutila.
In the upload, Nova Sutila provided a video depicting thousands of dead fish on the beach, which were then taken by the community at that location.
Nova Sutila also wrote a statement in her upload, ” Hopefully this is a good sign and this is the start of a better fortune, for the residents of Sikabaluan. Cangkuak fish pulls over to Sikabaluan beach, North Siberut, Mentawai Islands “.
Head of the West Sumatra Marine and Fisheries Service, Yosmeri, said that until now he has not been able to determine the cause of the death of the thousands of fish in Sikabaluan.
“I can’t confirm what the cause is, but usually if there are fish that die en masse, it is caused by several factors,” he said.
He said several factors could be the cause, such as natural phenomena, the environment and climate change.
As for the environment, he continued, it could be caused by poisoning fish , or someone catching fish using bombs.
Then another factor, namely extreme climate change, but Yosmeri assessed that because of climate change factors, this phenomenon should also occur in other coastal parts of West Sumatra.

South Korea said it has now culled 13.6 million birds as a preventive measure as the case count for H5N8 highly pathogenic avian influenza have reached 46. The culls include 10.2 million chickens, according to the country’s Ministry of Agriculture, Food and Rural Affairs.
Meanwhile, China’s General Administration of Customs said that the country has stopped imports of poultry from France due to H5N8 highly pathogenic avian influenza, with the halt effective from 5 January.
This comes after the French farm ministry Tuesday said it would cull 600,000 birds due to bird flu — 200,000 have already been culled with plans to cull another 400,000 birds. The country confirmed 61 outbreaks as of 1 January, with 48 in the Landes region alone, a key duck breeding area that supplies the foie gras industry.
India has now started the cull of poultry in the country, planning to cull at least 36,000 birds after both domestic and wild birds have died from bird flu. The country found its first case of the H5N8 bird flu one week ago, with the government now issuing a “high alert” and is calling on states to take “urgent measures” to prevent the spread.
China has emerged as a key market for US poultry, becoming the second largest for US broiler exports based on January-October 2020 trade data so trade blocks on other countries could provide some additional potential for US broiler/chicken exports to the country.
Meantime, Hungary will cull 90,000 turkeys in northwest areas of the country after bird flu was confirmed there on Wednesday 6 January. The H5N8 strain of bird flu is spreading rapidly across Europe and Asia.

The aquaculture industry in Laguna province lost P1 million to the recent fish kill in Sampaloc Lake in San Pablo City, but officials of the Bureau of Fisheries and Aquatic Resources (BFAR) said this would not disrupt the supply of tilapia in the market.
Tilapia, which is primarily grown in Sampaloc Lake, is the most affected of the four fish species cultured or naturally found in the 100-hectare freshwater body.
Some 9.8 tons, or 9,800 kilograms of tilapia, cultured in fish cages and another 100 kg found in open water turned up dead last weekend, said Sammy Malvas, the BFAR director for Calabarzon (Cavite, Laguna, Batangas, Rizal and Quezon). Tilapia growers, he said, lost P885,000.
“I don’t think it would have a huge impact on the tilapia supply in the market. Production continues in other areas,” Malvas said in a text message on Tuesday. The BFAR and the Laguna Lake Development Authority said what happened was a natural lake overturn, when the top and bottom water of the lake switch, leading to a reduction in volume of dissolved oxygen needed by fish to survive.
