HÀ TĨNH — A reddish streak has reappeared in the waters near aquaculture cages along central Hà Tĩnh Province’s coastline less than two months after it was first spotted in January.
Phan Duy Vĩnh, deputy chairman of the province’s Kỳ Anh District, said residents from aquaculture farms in Kỳ Lợi Commune reported that they had spotted a reddish streak on Monday morning. Soon after, environmental officials went to the site and collected samples for testing.
The reddish streak was about 30 metres long and dissolved in sea water after some hours.
In January, residents had spotted a reddish streak and reported it to authorities. The results of the test by the Ministry of Natural Resources and Environment stated that it had been caused by pollution from aquaculture. The commune is located near Vũng Áng Economic Zone.
Later, in February, a reddish streak appeared in Sơn Dương Wharf in the economic zone. This time the ministry’s test results said the streak had been caused either by algal bloom or a red tide.
Reddish streaks also appeared in central Thừa Thiên-Huế Province and Đà Nẵng City in February. Local environment departments there collected samples, but they too have come up with different reasons. While Thừa Thiên-Huế officials attributed it to a colour-changing algal process, Đà Nẵng officials said the colour was caused by the floating eggs of a tiny shrimp species. — VNS
