Thousands of dead fish wash up on Rinconcillo beach in Spain #fish #Spain
Thousands of small dead fish have flooded much of El Rinconcillo beach, in Algeciras, this Sunday. In principle, it is not known why the presence of so many dead fish on the shore may be due, but it is not ruled out that it is due to a natural phenomenon.
It is not the first time that large banks of very different species such as “gherkins”, “trumpeters”, “little stars” or different varieties of jellyfish are dragged by the sea currents or by the storms of Levante and gale, after the seabed has been agitated . The currents start the different colonies of algae and with them, the different species that live among them.
Ecologists in the area also point out that the floods of the Guadarranque and Palmones rivers are caused by an excess of fresh water that causes this situation, which, contrary to what may seem, may be making clear that the ecosystem is recovering.

39 TONS of fish die in a river in Dong Thap, Vietnam #fish #Vietnam
High density of farmers, plus low water levels, weak currents lead to lack of oxygen leading to massive fish deaths on Cai Vung river, Dong Thap province.
Dong Thap Department of Animal Husbandry, Veterinary and Fisheries has just analyzed results of causes of dead fish in Cai Vung river.
According to the analysis results, fish died due to local hypoxia. Dissolved oxygen content in water (referred to as DO) where dead fish occurs is only 1.0 – 2 mg / l, while the required oxygen requirement according to DO> = 4 mg / l.
The cause of this situation is the water level on Cai Vung tributary, the section passing through water in Hong Ngu district is getting low, combined with weak flow, dense stocking density.

Hundreds of dead fish wash up on beach in Pasir Ris Park, Singapore #fish #Singapore
National Parks Board (NParks) officers are looking into the cause of hundreds of fish deaths along a stretch of beach in Pasir Ris.
The silver-coloured fish, as well as several crabs, were spotted washed up at Pasir Ris Park on Monday morning (Feb 3).
Three cleaners were seen along the approximately 150m stretch of shoreline clearing the dead animals into large bags at about 8am.
NParks coastal and marine director at the National Biodiversity Centre Karenne Tun said that based on preliminary findings, the fish were mostly of the Hilsa kelee species, which is part of the clupeid family of wild fish found in Singapore’s coastal waters.
“NParks officers did not observe any dead fish or biodiversity along the surrounding coastal areas along Changi Beach, East Coast Park and Pulau Ubin, including Chek Jawa,” said Dr Tun.
There were also no reports of fish deaths at the nearby fish farms, she added.
NParks officers will continue to monitor the coastal beaches for anomalies and look into the cause of the fish deaths.
In April last year, thousands of fish died in the waters near Lim Chu Kang jetty and in nearby fish farms.
Fish farmers in the area sent motorboats out to remove and dispose of the dead fish that had surfaced in the sea.

TONS of dead fish appear in rivers in Aruanã, Brazil #fish #Brazil
Tons of fish appeared dead on the surface of the Vermelho and Araguaia rivers, in Aruanã, in the interior of Goiás. Videos recorded by residents show the fish floating in the water (see above). The Environment delegate, Luziano Carvalho, speaks in tons already collected this Monday (3), when the images were more strongly shared on social networks.
What draws the delegate’s attention is that the fish that appears in the images is the cascudo, a resistant species that is difficult to be contaminated. For this reason, the researcher initially works with the line that someone polluted the Rio Vermelho, even if in a guilty way, that is, without intention.
