deadfish III @ northwestern singapore - July2013

It appears that the local fishfarms are deliberately dumping deadfish into local waters. There may have been a 'depleted oxygen' incident affecting the Northwestern waters off Lim Chu Kang.

This 'dry weather-no rain-low oxygen' explanation favours the fish farmers but it of course (perhaps the fish farmers are simply overstocking their pens?) does not explain why the other fish in the area (like those free swimming in the Sungei Buloh Reserve) did not seem to be affected. If they had, there would have been many many more dead fish seen floating.

The story seems to be that proper disposal of dead fish was organised and that none of the affected fishfarms had dumped fish 'over the side'. Instead all dead fish were collected and transported to the Lim Chu Kang jetty for proper disposal.

Sadly this explanation does not fit what was seen in the waters around Lim Chu Kang and the SBWR

It may be that the local fishfarms did not throw away dead fish. However, it looks like they released dying fish into the surrounding waters. Why wait for the soon-to-be-dead fish to die? Mercy release? This now unpopular quasi-religious practice never did involve the release of dying animals, did it? 

What's even worse is finding obvious signs that dead fish were 'released' despite the denials.

Here are pics from the northwestern coast showing fish meal bags (the usual container for fish meal as supplied to aquaculture establishments in Singapore) stuffed with dead fish. Now this makes the denials smell ... fishy. Who would place live but dying fish in such bags and leave them adrift to reach the shore? So dead (or maybe including dying) fish were in fact placed in bags and set adrift and away releasing the farmers from certain environmental obligations and responsibilities.



If visiting ships in port have to pay for a trash collection service where trash is collected from them, then our local fish farms should also pay for similar trash collection. It should not be left to the local fish farms to bring their trash to a determined trash point on the shore. We know that expectation is a failure now isn't it?

Whilst some fish farmers may comply, there are others who clearly do not. These recalcitrant farmers take advantage of the cover of darkness to dump their waste anywhere they feel like it. And there is more than dead fish generated by these off-shore farms. 

The workers living on these floating farms generate waste as well...both human as well as general household waste. (General waste includes, inter alia, styrofoam, plastic bags, empty fish meal bags, bottles, lightbulbs, lubricating oils and grease for machinery, etc.) Where does all this go if the trash collection points are not used. (If you want to know more about Singapore's coastal trash, visit http://coastalcleanup.nus.edu.sg/.)

There desperately needs to be a more formal system of trash collection from licensed fish farms.

Given the poor track record as shown through this incident,  perhaps it is time for Parliament to legislate standards and practices at fish farms and this could include compulsory fee-based trash collection to leave no doubt as to what really happens to the trash generated 24x7x365.

Or we could all just continue pretending that there is no problem and that both our fish farms and our waters are perfectly fine. 

Of course, there are many sources of pollution in our waters and the locally licensed fish farms are but one. Will any face prosecutions for this series of dumplings? Probably not.... but why not?

deadfish @ northwestern Singapore coast off SBWR & LCK - 29Jun2013

Visited SBWR this afternoon and was surprised to see many many floaters - fish - all dead and stinky. They seemed likely to be milkfish and mullet. These are commonly farmed at the off-shore fish farms located off Lim Chu Kang and the SBWRI did not see any dead giant mudskippers, archer fish or sea bass or needlefish, but there was one dead and bloated catfish near the main bridge at Sungei Buloh. Perhaps that had been scavenging on the dead milkfish or mullet. 

The scene at Lim Chu Kang beach (beside the AVA jetty)...

The whole beach was strewn with dead fish (and not forgetting copious amounts of styrofoam and other rubbish). 

I had a friend from Denmark visiting Singapore whom i had dragged along to visit SBWR and he was (with jaw dropping silence) shocked to see the condition of the Lim Chu Kang mangrove and beach and the items left behind by squatting fisherfolk temporarily resident along the beach.

















Meanwhile at SBWR ... the reserve was being pervaded by the certain pungent smell of decomposing fish. Lots of them. 




These pics are from the Mangrove Boardwalk area. Apparently, the dead fish started appearing on Friday and SBWR staff had cleared what they could reach but there was just too many dead fish coming in from the coast with each incoming tide. 








Many dead fish got stuck on the rocky bunds and also on trees once the tide receded. The hot afternoon air wafted the rotting stench easily and it was impossible to escape the pungent smell (even with an N95 mask which obviously was not designed to stop smells).





including some fish stuck on trees ...


The Lim Chu Kang jetty has two dumpsters, one for biological waste and another for general waste. It is obvious that the fish farm(s) responsible for the dumping are not using these waste collection containers. 

Could the crocs, monitor lizards, otters and other scavengers in the area face possible poisoning from whatever killed the fish (despite their strong stomachs). 

There could be quite a few possible causes ...
an E-coli outbreak?
chemical poisoning?
algal bloom?
depleted oxygen?
(Update 03July2013 : apparently, it was low oxygen levels which caused the deaths)

Failing good reason for the dumping(can there be any?), the farms responsible should be prosecuted.
Dumping puts the surrounding environment (and other farms) at risk. 
It pollutes the water making it unsafe for all.

eagleantics @ marina bay - June 2013

Was about Parliamant House when i noticed two adult white-bellied sea eagles atop High Street Centre. One took off towards Fort Canning whilst the other stayed put on the 'finger'. Nice of the architects to make such a perch for the area's resident eagles. The views must be stunning (on days without the haze).

Going up Fort Canning, i missed locating the WBSE or the two fledged juveniles. This was the first time i was not able to locate any of the birds in any of the usual perch points. Walking back towards the Southern part of Fort Canning, the two adult birds were atop the finger again. This time, they started their trademark territorial cackling. It could be heard clearly across the distance. Perhaps they were calling to the juveniles to join them.

One of the adults took off towards Marina Bay followed shortly by the other. Time for some last minute fishing. A quick walk over to the Marina promenade proved fruitful. One of the adults came flying in low past the floating platform clutching a large fish in its talons. It flew above the bandstand and decided to circle around. It kept doing this whilst gaining height with each upward spiral before finally continuing its flight path across the Padang. It settled atop High Street Centre. Meanwhile, the other adult WBSE came by also gripping a fish. This one just powered straight on across the top of the Esplanade durians across the Padang. I lost sight of it and it must have taken a different route perhaps back to Fort Canning.

white-bellied sea eagle escapes a murder of crows @ SBWR - May 2013

The white-belied sea eagle, Singapore's largest resident bird, was enjoying a sunny morning on a bare branch at one end of Pulau Buloh across from Platform 1 at SBWR. It was soon joined by a single crow but within minutes, there were quite a few more crows crowding the surrounding branches. 
As the crows grew in number, they started leapfrogging between the nearby branches constantly repositioning themselves around the eagle which was many times their size. It seemed as if there was intelligence behind the repositioning like a chess game being played on the chequerboard of branches.

The eagle was becoming increasingly concerned with the attention by the ever increasing crows. Soon, it was time for the crows to show the eagle who was boss of that corner of Pulau Buloh.

The eagle quickly decided to take flight after a crow brushed up too close against its wing. Time to escape a murder. It was immediately chased by some of the other crows which had ben waiting on the nearby branches. The eagle flew off to a less crow-ed (pun intended) part of the reserve.
