I have seen such huge fish traps along Changi Boardwalk on almost every survey throughout the years. There are other impacts from line fishing and net fishing too.
Changi Boardwalk is a magnet for fishermen. On a typical weekend when the tide is right, segments of the boardwalk over the water is completely taken over by fishermen who lay fishing rods, traps and lines in dense numbers. I shared more about how poorly managed boardwalks can do more harm than good in this old blog post. This is what I saw on 10 Jul 2016. This is not very different from what I saw in 2009 in the same place.
Yellow arrows point to lines in the water attached to traps. These lines are placed on both sides of the boardwalk. |
The news of the otters' deaths was first posted on OtterWatch on 26 Apr 2018.
Besides killing large animals, Large traps also squash and damage other marine life, reducing the biodiversity beneath the boardwalk.

Fishing lines kill more than fish
Even in a single fishing line can entangle immobile animals.
Victims include birds, which die a slow and cruel death as they get entangled in fishing lines abandoned by fishermen.

Long large fishing nets
Fishermen also deploy long large nets from the Changi Boardwalk. During a survey on Aug 2016. I saw what looks like a fishing net about to be laid from the boardwalk with a long pole. There were also about 20 fishing rods tied to the boardwalk railings and large styrofoam boxes ready for the catch. The tide was super low and it was a weekday. I was surprised as I thought this sort of intensive fishing only happened at high tide and on weekends.
Such nets are often found abandoned under the boardwalks, like this scene in May 2017. Such nets continue to kill until they are removed.
While coastal boardwalks can allow ordinary people to visit a shore without trampling it, there are also many unintended harmful long-term consequences that can occur. These can be avoided by holistic planning for ecologically sensitive construction and maintenance, and good management of boardwalk usage.
