Trawling

Real World Example

Imagine you’re vacuuming your living room, trying to pick up every little piece of dust and debris scattered on the floor. Similar to how the vacuum moves across the carpet to collect everything in its path, trawling involves dragging a net through the water to catch fish. In this analogy, the vacuum cleaner is like the fishing boat, the floor is the ocean, and the dust and debris are the fish being gathered by the net.
