Go to East Coast Park at 11.30pm and listen to the sound of the waves crashing against the breakwaters for an hour.
When I was younger, I spent as many as three nights a week sitting quietly on an unlit breakwater, for stretches of eight hours or more, quietly watching for the quivering of a glow stick on a rod tip to indicate a bite. I had nearly forgotten the loudness of the waves until a return ten years later.
By the transformation of original coastlines into steep inclined boundaries formed by rocky granite breakwaters, the perfect habitat was formed for a new and invasive species of fish: the Sabah giant grouper. Hybridised specifically for consumption, it is one of the predominantly farmed species in Southeast Asian aquaculture. Escaped and released fish find dwelling within the crevasses of the breakwaters; their voracious appetites unbalance coastal food chains by decimating native fish populations. They can no longer be re-captured by nets, only by the strategic angler with rod and line.
