What is killing fishes at Pasir Ris?
By Ria Tan, 25th February 2015;

I headed out in the afternoon to see if dead fishes were washing up at Pasir Ris Park beach.

There was a huge dead barracuda, and a few other large dead fishes. I didn’t see many dead farm fishes. Dead wild fishes were also reported over the last two days at Sembawang and Changi. The risks of fish deaths are rising in the weeks ahead as there will be no good spring tide to flush the waters around Pasir Ris and Pulau Ubin until April.

I checked out the western side of Pasir Ris today, the same stretch I checked three days ago on 22 Feb (Sat). Alas, today I came too late and the cleaner had already cleaned the high water tide line for the day. So I only checked the low water line of the most recent tide.

I also surveyed a stretch of beach wasn’t cleaned yet. So I could check the high water tide line for today. Here, I saw a few very crispy large dead fishes.

I also surveyed the western stretch of shoreline that is outside the Pasir Ris Park proper and thus is not cleaned at all. Here, I saw some really large dead fishes.

This large Pickhandle Barracuda appears to have been one of the casualties of a mass mortality event that just took place in the sea off Pasir Ris.

I heard the water was not quite right at Pasir Ris. So I had a quick look there yesterday.

I saw white powdery insoluble stuff deposited at most recent mid-tide line. Dead fishes of various kinds large and small every 20 steps or so. More below about why it is important for human health, to find out what is killing the fishes.
