Step 1: Understanding the Concept:
Different line fishing methods are classified based on whether the gear is static, drifting, or actively towed through the water.
Step 2: Detailed Explanation:
Trolling (or using troll lines) is an active line-fishing method where one or more lines equipped with natural baits or artificial lures are dragged (towed) through the water column behind a moving vessel.
Outriggers are long poles extended from the sides of the boat to spread the lines wide apart and prevent them from tangling during towing.
This method is highly effective in targeting fast-moving pelagic predatory fishes such as tunas, barracudas, Spanish mackerels, and billfishes.
Step 3: Final Answer:
The method described corresponds to Troll lines, which is option (B).
