lim chu kang jetty mangrove-beach @ 02 Feb 2014

Went down to Lim Chu Kang jetty to have a look at the condition of the beach.
After all, it has been some time since the last major cleanup on 10 Aug 2013.
(See these links for the yearly National Day cleanups : 2011, 2012, 2013) 

The scene was depressing (as usual and as expected). 

Obviously, the current trash disposal arrangements for the offshore fishfarms are insufficient.

This is the large skip tank before the jetty into which all the offshore fishfarms are supposed to dump their general trash. There is a separate smaller bin for biological waste. These are regularly cleared by 'V8 Environmental' under a contract. (I wonder if there was a tender for this??)

The most unsupervised jetty in Singapore... 
(Civet cats disappear into woks but that is a different story for another day).

This is at the corner which meets the Police Coast Guard base fence. There was also a lot of trash on the inside of the fence. I doubt anyone clears the trash on either side of the fence.

A fishmeal bag nicely tied up. 

There is a huge amount of plastic and expanded polystyrene (EPS foam) accumulated at this corner.

...including some ubiquitous blue chemical drums.

a view of the mangrove shore front. That big black bumper has been there for a few years. It is super heavy.

A makeshift shelter to while away the day. 

the path leading to the mangrove shore...


Lots and lots of mainly plastic trash and EPS foam.
 more plastic trash and EPS foam.
 and even more plastic trash and EPS foam with all kinds of general waste (eg. light bulbs) as well.
 the waves bring in more trash. (spot the plastic trash hidden by the fallen leaves)

Fish meal bags are always a common sight on this shore. Where could this have come from? Can we simply blame the Malaysian fish farms for tossing over the side trash and the currents for bringing the trash from Malaysian waters? I think not.... why? There might be some trash coming from across the Straits, but we clearly do have sources much closer to our shores. See the last two pics in this post. 
some larger pieces of unwanted trash strewn all over the place.

The smaller blue bin supposedly used for biological waste (eg. dead fish) is seen in front of the much larger general waste skip tank.

NOTE : there is no similar skip tank and separate biological waste bin for the offshore fishfarms operating from Changi Village Jetty.

Are ALL the fish farms using these receptables? Sadly, No. Perhaps some are but not all of them.

The item pictured below seen on the shore is clear that trash from our local fish farms are finding their way into the coastal waters.
What is it?
This is a plastic bag which used in the supply of ice by JM Ice, a local ice supplier.
JM Ice supplies ice to various offshore fish farms using these bags. 
Obviously, one of the Singapore offshore fishfarms carelessly disposed of this bag... and it ended up on the shore. (Entirely plausible and it seems to be the most likely explanation though there may be another less likely source of this bag being found on the shore).

It would be unfathomable to think that JM Ice supplies the fishfarms across the Straits of Johor with ice. Is it?

Perhaps a trash collection system serving each of the fishfarms on a regular basis can be implemented for the fishfarms including a proper monitoring system to check on the fishfarms.

There needs to be a better system in place. 
We need to take better care of our marine environment.

Thoughtful clips worth watching ...

semakau seagrass lagoon @ 01Feb2014

Went on a short boat ride looking for oil from the recent ship collisions.
(see Link 12)

On the way to Semakau, ...

Bukom's southern seawall seems to have some dark banding indicative of an oil-spill. The brown spots could be some other localised spill. Wonder what could have caused those spots.

The bad news is that Semakau's northern shore may have had some exposure to some of the oil-spill. There was a distinct dark line on the seawall. 
Whilst the others in the recce went to explore the Northern shore and Terumbu Semakau, I went Westwards along the seagrass lagoon.

The good news is that it looks like Semakau's seagrass lagoon was clear of oil. The seagrass lagoon and shore were 'normal'. No oil seen on the inter-tidal area, shore or on the fringing mangrove trees. That is a good sign.
'Normal' however means a whole lot of trash on the high shore line. Lots of plastic items which had floated in with the tides over many many years still line the shore. 


note the styrofoam box high in the tree

a 3 foot long fluorescent light bulb

bundles of rope




an SPC oil drum

a plastic road barrier

a huge piece of blue plastic sheeting


an old sofa

one of the gazillion mineral water cups and water bottles

a large prawn feed bag

This was a balloon stuck high up on a mangrove tree.


We really should take better care of our marine environment.

At the southern end of the seagrass lagoon, lots was happening.
This chap had harvested quite a few large mud crabs from the mangrove inlet.

Another few were harvesting shells from the inter-tidal zone whilst another laid out a long driftnet on the inter-tidal zone.



 A ciggarette butt was care-less-ly dropped in the water.

A quick chat with one of them showed them to be contractors at the landfill site out to gather a quick seafood dinner. 

They promptly agreed to return their haul to the lagoon and to recover the driftnet that was being laid out.
 No fan clam soup tonight.

The men soon left in their vehicles parked atop the service road. 
The mud-crabs were however not released. Looks like crab curry tonight.

 

There were two long driftnets long abandoned at the South-Western tip of the seagrass lagoon. These looked like they had been on the inter-tidal for some time. (There was a third driftnet at the Northern part of the seagrass lagoon.) 

 A super long driftnet attached at one end to the replanted mangrove trees and the other to a rock on the inter-tidal zone. 

These carpet anemones will not last very long with the driftnet filaments draped over them.



These driftnets will need some tedious work to remove them and the various organisms that become stuck in them.
That's a task for another day with more time. 

It soon got dark during the long walk back up the lagoon.

Can you name the following ?
Have a look here for help.





Good night Semakau!
