Step 1: Understanding the Concept:
Specialized artisanal fishing methods and gear: frog harvesting (Rana tigerina Hoplobatrachus tigerinus) traditionally employs baited bamboo cage traps, hand nets, and nocturnal light-luring.
Step 2: Detailed Explanation:
In artisanal fishing gear and frog harvesting:
- In freshwater wetlands, paddy fields, and marshes, commercial capture of edible bullfrogs (Hoplobatrachus tigerinus Euphlyctis hexadactylus) was traditionally conducted using Specialized Traps (A) (bamboo cage traps, funnel traps with live insect baits), as well as hand collection with torches (night light-luring) and scoop nets.
- (Trawlers and dredges are heavy marine gears).
Step 3: Final Answer:
Thus, the gear used for frog fishery is Traps, matching option (A).
