KUNINGAN - Tens of tons of fish belonging to residents in the floating net pond of the Darma Reservoir, Kuningan Regency, West Java, died suddenly due to the "upwelling" phenomenon in recent days.

"One tonne of fish died in my pond, but if it's combined with other farmers, it's up to 20 tons more," said a fisherman from the floating net at the Darma Reservoir, Jagara Village, Kuningan Regency, Suhanda, quoting Antara, Wednesday, June 1.

According to Suhanda, the death of tens of tons of fish in the Darma Reservoir was due to the "upwelling" phenomenon, where the surface of the cold and heavy water sinks downwards, then those under the warm reservoir rise up carrying poison, so that many fish die.

This incident, continued Suhanda, was not the only time, but had happened several times, especially when the weather in the reservoir had no sun, and this was already known to all farmers.

"In fisheries science this is an 'upwelling' phenomenon, so the water contains poison," he said.

For this reason, said Suhanda, many farmers harvest their fish and sell them at low prices, this is to avoid bigger losses.

On weekdays, fish farmers are sold for Rp. 25 thousand - Rp. 30 thousand per kilogram, that is for tilapia and gold, but this time on sale per kilogram is only valued at Rp. 10 thousand.

"We sell cheap, rather than increase the loss, it's better to sell it," he said.
