Here's a discussion of this on facebook.
I started at Punggol Marina Country Club where Darrin Neil had reported: "Yesterday (28 Feb) there was nothing. Today (1 Mar) the marina was littered with thousands of (dead) fish. Barracuda, puffer fish, cat fish, grouper and even a sea snake."

Sean Yap, Sankar and Ing Sind had been sharing. There were also many large catfishes and eel-tail catfishes. As well as large cuttlefishes.
Serin Subaraj and Germaine Leng found a dead seahorse washed up. Also a worm. When the base of the food chain gets affected, it cannot be good. Thanks to Sean Yap for the alert. [Update 4 Mar: Koh Kwan Siong also shared that at Changi, he saw toadfish, seabass, juvenile groupa.]

[Update 4 Mar: Thanks to Shahrer Sam'on for sharing these photos taken from Changi Boardwalk on 2 Mar:
Ivan Kwan of Monday Morgue also shared his thoughts about the mass fish deaths. He said: "The scale of this year's mass death has been really alarming; a similar event took place in February 2014, but it seems like last year's was less severe compared to what's happened over the last 2 weeks. These episodes have been blamed on plankton blooms, which makes me wonder about the health and resilience of our marine ecosystems. It is worrying to think that this could become a regular occurrence."
What is happening at the fish farms?
This morning, a video of dead fishes floating around the fish farms was shared by Sea Angel Boatfishing on facebook.
Philip Lim also shared the fish farmers' point of view of mass fish deaths
AVA treat fish farmers like "slaves", say fish farmer from The Online Citizen on Vimeo.
Fish farmer says that AVA has not helped them nor took actions for predicted HAB from The Online Citizen on Vimeo.
What are mass fish deaths and what causes them?
Wikipedia has a good entry on fish kills which highlights: "Fish kills are often the first visible signs of environmental stress and are usually investigated as a matter of urgency by environmental agencies to determine the cause of the kill. Many fish species have a relatively low tolerance of variations in environmental conditions and their death is often a potent indicator of problems in their environment that may be affecting other animals and plants and may have a direct impact on other uses of the water."
My thoughts about the mass fish deaths
The large numbers of wild and farmed fishes that I saw today over many locations on our north-eastern shores is worrying. I hope scientists and authorities are looking into the extent of the mass fish deaths, what is causing this and what steps can be taken to improve the health of the ecosystems to avoid a recurrence of such mass deaths. I hope AVA is helping all fish farmers to dispose of their dead fishes properly.
If there is a positive side to this very sad situation, it is perhaps that more people have come to realise that Singapore's shores are rich in marine life. As this SGAG article demonstrates.
You CAN make a difference: Dead Fish Alert!
Please help me monitor dead fishes washing up on the Johor Straits. Please let me know if you see large numbers (more than 10) especially of large dead fishes (more than 20cm long) washing up on the northern shores such as Pulau Ubin, Lim Chu Kang, Sungei Buloh, Kranji, Sembawang, Punggol, Pasir Ris, Changi.
More info about why it is important to find out what is killing these fishes, and lots more links, in this previous post.
