Dead fish update: Pasir Ris, Seletar Dam, Sembawang
By Ria Tan, 27th February 2015;

Today I had a quick look at the western shores of Pasir Ris. There were a few large dead fishes and many smaller ones. All appeared to be wild fishes. Also, dead cuttlefishes and horseshoe crabs. I didn’t see any dead farm fishes. Sightings of dead fishes at Seletar Dam (Benjamin Li) and Sembawang (Tan Sijie) were also shared recently.

Timothy Hromatka, a fish farmer off Ubin also shared more about the recent fish deaths on the farms.

Reporting from Seletar Dam facing Johor side. Unusually strong pungent smell from the sea got my curiosity as I was riding past this stretch.

Along the shores was a zone of 2 metres with dead horseshoe crabs (F. Limulidae), Mangrove Whipray (Himantura walga), Flower Crab (Portunus pelagicus), Grouper (Epinephelus sp.), Sand Whiting (Sillago sp.), Green Chromide (Etroplus suratensis), Spotted Scat (Scatophagus argus), Barramundi (Lates calcarifer), Toadfish (F.

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.
