A small team were clearing up the dead fishes that washed up here last night. And possibly also the day before.
reported in the media yesterday. Mass fish deaths are a reflection of water quality and have impact on public cleanliness and health.
Sungei Buloh Wetland Reserve
I made a brief stop at Sungei Buloh Wetland Reserve Extension. There were only a scattering of dead fishes and most do not look recently dead.
Are the mass fish deaths in the northwest coming to an end?
I hope these sightings today means that the mass deaths are tapering off. But alas, I fear things may get worse before it finally ends.
First, we have been having a series of heavy downpours in the northwest. After a dry spell, all that rain will wash all manner of built up stuff down into the coast. The un-dammed water courses in the northwest pass through many farms which directly dispose of their effluents into these drainage systems.
Second, in a few days' time, we will be experiencing neap tides. During this period, the difference between the high and low tides are minimal which means there is less tidal flushing. More about the tides in Singapore.
Such conditions of increased nutrient inflow and low water exchange can create conditions that are favourable for situations that result in mass fish deaths. More in this old post and more about red tides.
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, Woodlands Waterfront, Sembawang, Punggol, Lorong Halus, Pasir Ris, Changi.
There are too many shores for me to personally check, so I really appreciate any info or photos that you can share.
