Head of the West Lampung District Fisheries Service, Lampung Province Kamaludin stated, the number of dead fish in Ranau Lake tends to increase. Until now it has reached 250 tons.
"The number is likely to increase, because until yesterday, Sunday the dead fish had reached 250 tons," he said in Liwa, West Lampung, as reported by Antara, Monday, June 16.

According to him, the losses suffered by the farmers are still uncertain, but it is estimated that they will reach billions of rupiah.
"If we calculate it from 250 tons to rupiah at a price of Rp. 25 thousand per kilo, around Rp. 5 billion, the total loss is," he said.
Regarding the cause of death of the fish, he said that his party suspected that the levels of sulfur were rising.
"The sulfur levels rose, as a result, oxygen levels in Ranau Lake fell, resulting in fish deaths," he said.
For the time being, he said, farmers will use fresh fish for consumption.
"Yes, while 25 to 30 percent of the fish that are still fresh are used by them for consumption and sale," he said
Regarding dead fish, they will be dumped somewhere and fertilizer will be made. "Yesterday, it was sprayed with fermentation and mixed with soil," he said.
He explained that Lumbok Seminung is an area known as a nilap fish center in West Lampung.
The production of tilapia in Seminung Lumbok in a year can reach 6,000 tons with sales to various regions such as South Sumatra, Jakarta and Surabaya but not a few are marketed in Lampung Province, said Kamaludin.
