A family of ten were at the Jurong Lake area not for a picnic but to release fish into the lake. They walked up to the edge of the lake with bags of eels and fish that they released into the lake.
We went to the security guard to ask that she stop them but were told that the area outside Japanese Garden is managed by PUB. Here's the family each release their quota into the lake.
The anti-litter campaign has worked as the family gathered up all their empty plastic bags. The no release rule is obviously one that no one seems to care for.
