Step 1: Understanding the Concept:
Hook-and-line commercial and recreational fishing: artificial lures utilize vibrant colored feathers, reflective bucktail fibers, and metallic spoons to visually trigger predatory feeding strikes.
Step 2: Detailed Explanation:
In line fishing gear and angling technology:
- Lures (Artificial Lures Feather Lures Flies) (D): Artificial fish-attracting devices constructed using brightly colored feathers, synthetic flash fibers, bucktail hair, metallic spinners, plastic skirts, or wooden wobblers mounted onto single or gang hooks.
- In trolling lines and surface handlines, they visually simulate the motion, flash, and color of escaping prey fish, triggering predatory strikes from sight-hunting pelagic fishes (tunas, mackerels, seerfish, barracudas).
Step 3: Final Answer:
Hence, colored feathers or fibres used to attract fishes are called Lures, matching option (D).
