Thousands of floating dead fish have bizarrely appeared on the top of a scenic lake in Indonesia.
The mass death of the fish in Maninjau lake, West Sumatra province, is apparently caused by a sudden change of weather conditions, according to fishery officials.
It is not the first time locals have seen the unusual phenomenon – at least 7,000 tonnes of fish bred in floating fish farms at the lake died from poisonous sulphur and fish-feeding sediments stirred up from the lake bottom by storms in 2009.

A sea of dead fish is covering the waters of Maninjau lake in West Sumatra province, Indonesia. The mass death of the fish is apparently caused by a sudden change of weather condition according to fishery officials
At the time the West Sumatra Maritime Affairs and Fisheries Agency said the mass deaths were caused by an upwelling, with sulphur-rich colder water from the bottom rising to the surface due to a drastic weather change.
The 99.5-square-kilometer Maninjau is a volcanic crater lake in Agam district.
The lake, which has a depth of close to 500 metres, is known for its mountain-rimmed panorama and has become one of West Sumatra’s famous tourist destinations.
