An effective technique
When trolling, the idea isn't to fish deep, but to work a lure in the water column where the fish are patrolling, often in the middle layer or just below the surface. Light inshore trolling with small plug lures, soft plastics, or even light spoons can yield good results, provided you stick to modest sizes, generally around 5 to 9 cm.
The tackle should remain light and responsive. A lightweight rod, thin braided line, and an inconspicuous leader allow small lures to swim naturally without arousing excessive suspicion from the fish. The oblade has a small mouth and responds well to small prey; therefore, it?s best to avoid rigs that are too heavy or large hooks that restrict the lure?s action.
The Right Conditions
In terms of conditions, trolling becomes particularly effective when the oblades are actively hunting: warm water, slightly choppy seas, the presence of foam, surface activity, or fish visible along the edges. Breaklines, rocky points, harbor entrances, and spots near hunting grounds are often excellent areas to explore.
In practice, the best approach is to retrieve slowly to moderately with a small plug or a natural-looking soft plastic lure, varying the depth until you find the right water column. If the fish are following but not biting, it may help to use a smaller lure, switch to a more natural color, or slightly increase your retrieve speed to trigger a strike.
It?s a fun, visually appealing, and fairly accessible form of fishing, but one that requires finesse. The oblade isn?t a massive predator: it prefers modest prey, a subtle presentation, and a fast retrieve, which makes light trolling a logical method for targeting it from a boat or while drifting under control.
