100 TONS of fish suddenly die in Lake Toba, North Sumatra, Indonesia
100 tons of fish died suddenly in Lake Toba , North Sumatra (North Sumatra) some time ago. The water quality in Lake Toba is also one of the highlights.
Rusdi Leidonald, an academic at the Aquatic Resources Management Study Program at the University of North Sumatra (USU), said the sudden death of fish could be triggered by a decrease in water quality. According to him, the decline in water quality can be triggered by many factors.
“There are many things that can cause a decrease in water quality,” said Rusdi.
He said one of the triggers for the decline in water quality is the weather factor. According to him, the explanation of the Samosir Agricultural Service about the strong winds that triggered the water to rotate so that turbid water rose to the top of the lake could be the cause of the decline in water quality.
“Theoretically it can cause it,” said Rusdi.
However, Rusdi said the problem of decreasing water quality must be further analyzed. Rusdi said that his party does not have the latest data on the water quality of Lake Toba.
“We at USU do not yet have the latest data regarding the current state of Lake Toba and I am sure that the response of the regency and municipal government around Lake Toba and the provincial government also has competence in this field,” he said.
Rusdi explained that strong winds are not only disturbing the water quality in Lake Toba . He said that strong winds had also disturbed the quality of water in several lakes in Indonesia.
“This also often happens in other lakes, such as Lake Singkarak in West Sumatra,” said Rusdi.
Research related to water quality in Lake Toba was conducted in 2014. The Director General of Pollution and Environmental Damage Control at the Ministry of Environment and Forestry at that time, Karliansyah, said that the lake which was a tourist attraction was contaminated with fish feed.
“So in Lake Toba there are many floating cages from companies and indigenous people. From these cages a lot of fish feed is deposited,” said Karliansyah during a conversation.
