Daily Decay (20th June 2018): Unidentified Grouper (Epinephelus
sp.) @ Changi
This was one of the many casualties of a fish mass death in late February and March 2015, caused by a harmful algal bloom in the eastern Straits of Johor.
Several species of Grouper (as well as hybrids) are raised in offshore fish farms in the Straits of Johor, so this individual might have been a farm escapee.

This was one of the many casualties of a fish mass mortality event that took place in the eastern Straits of Johor in February 2014, supposedly caused by a plankton bloom.
Daily Decay (27th May 2018): Unidentified Snapper (Lutjanus sp.) @ Changi
This was one of the many casualties of a fish mass death in February 2014, caused by a harmful algal bloom in the eastern Straits of Johor.
Many of the offshore fish farms in the Straits of Johor raise several species of Snapper, such as John’s Snapper (Lutjanus johnii) and Crimson Snapper (Lutjanus erythropterus), for human consumption, so this carcass is likely to be one of the farmed fishes, instead of being of wild origin.

) @ Pasir Ris
This was one of the many casualties of yet another fish mass mortality event that was triggered by a harmful algal bloom in the eastern Straits of Johor in February and March 2015.

15th May 2018;
National water agency PUB is investigating a report of dead fishes spotted in Sungei Tampines on Monday afternoon (May 14).
In a Facebook post on Tuesday, PUB said that the dead fishes have been removed after they were seen in the river between Pasir Ris Drive 1 and Pasir Ris Drive 3 at 2.20pm.
Sungei Tampines flows through parts of Tampines and Pasir Ris before draining into the sea.
“Online water quality sensors and in-situ water quality readings show water quality is within the normal range,” PUB said in the post.
There is no impact on the quality of drinking water, it added.
“PUB has not observed any visible signs of pollution on the site that may be the cause of fish kill,” it said, adding that it will investigate further.
In 2015, a 1.1km stretch along Sungei Tampines was outfitted with new decks and a community plaza to bring people closer to the river.
The project was part of a move by PUB to rejuvenate Singapore’s drains, canals and reservoirs.
