Punggol Point Losing Fishermen

The catch must be bad nowadays.  There are less and less men doing fishing nowadays at Punggol Point.  Even the Cisco police tells me the catch is poor.  The men are doing recreational fishing so will not starve.  However, the joys of catching some good fishes is diminishing and therefore they are likely to fish somewhere else.  Usually, there is a group of 5 or 6.  These days, I see only one or two.  I wonder if the pollution is getting worse or the fishes are not reproducing as they declined due to overfishing by the commercial fishermen.  Luckily, the baby fishes are still plentiful and I could catch them for my arowana.
