When choosing fishing line, it is necessary to comprehensively consider multiple factors such as target fish species, water environment, fishing method, equipment compatibility, and budget. Here is a specific analysis to help you accurately match your needs:
1. Select based on target fish species
Small fish (crucian carp, white strips, horse mouth, etc.)
Wire number: 0.4-1.5 (nylon wire or fine carbon wire)
Features: High sensitivity (transmitting slight bite signals), thin wire diameter reduces fish alertness.
Example: Wild fishing for crucian carp uses 0.8 nylon thread, while Luyamou uses 0.6 carbon thread.
Medium sized fish (carp, grass carp, mandarin fish, etc.)
Wire number: 1.5-3.0 (nylon/carbon wire) or 2.0-4.0 (PE wire+carbon lead)
Features: Balancing tension and concealment, carbon or PE wire is suitable for obstacle areas such as aquatic plants and reefs.
Example: For black pit carp fishing, use 2.5 nylon line, and for lure carp fishing, use 1.5 PE line+30cm carbon leader.
Large fish (blue carp, silver carp, bighead carp, sea fish, etc.)
Line number: 4.0 or above (mainly PE line)
Features: Requires ultra-high tensile strength, PE wire paired with thick front wire (such as carbon wire or nylon wire) to prevent wear.
Example: For sea fishing for tuna, use a No. 8 PE line+100cm 80 pound carbon leader.

2. Choose based on the water environment
Clear water/water bodies with high transparency
Priority carbon wire: refractive index close to water, difficult for fish to detect.
Example: Fishing for sea bass in a reservoir uses a 1.0 carbon line to reduce fish alertness.
Muddy water/deep water
Optional fluorescent color line: convenient for observing the status of the line group (such as whether the sub lines are knotted).
Example: Fluorescent green nylon line is used for night fishing of carp, while orange PE line is used for deepwater fishing.
Obstacle areas (aquatic plants, rocks, tree branches, etc.)
Priority PE line: Strong wear resistance, paired with carbon front to prevent wear.
Example: Catching carp in Caodong requires using a 3rd PE line and a 50cm 4th carbon leader.
Flowing water/rapids
Choose high-density wire: carbon wire or nylon wire with lead sinker to quickly sink to the bottom and avoid being washed away.
Example: Use 0.8 carbon wire and a small lead sinker for fishing at the mouth of a stream.

3. Choose according to the fishing method
Taiwan Fishing/Traditional Fishing
Main line+sub line combination: The main line uses nylon wire (soft and easy to throw), and the sub lines use thin nylon wire or carbon wire (high sensitivity).
Example: Fishing for crucian carp with main line 1.2 nylon line and sub line 0.6 carbon line.
Luya Fishing
PE wire as the main component: it has no ductility and transmits clear signals, paired with carbon front anti abrasion.
Example: When fishing for sea bass, use 1.5 PE line+40cm 6 carbon leader.
Sea fishing/boat fishing
Large PE wire: To cope with the pulling force of large fish, it is paired with a metal front wire or steel wire to prevent shark bites.
Example: When fishing for grouper, use a 10 meter PE line and a 1-meter steel wire as a guide.
Ice fishing
Fine thread+high sensitivity: The ice cave space is small, and a fine thread (such as 0.6 nylon thread) is needed to reduce resistance.
Example: Ice fishing for crucian carp uses 0.8 gauge transparent nylon line.

4. Equipment compatibility
Fishing rod tuning
Soft rod (37 adjustable): equipped with fine thread (such as 0.8 nylon thread), utilizing the elasticity of the rod to buffer tension.
Hard rod (19 adjustable): equipped with thick thread (such as PE thread No.3), quickly control the fish to prevent detachment.
Fish Wheel Type
Spinning wheels: compatible with nylon thread, carbon thread, PE thread (pay attention to the smoothness of the outgoing line).
Drip wheel/drum: prioritize PE line (to reduce the risk of wire breakage), paired with carbon lead.
Float/lead weight
Fine line: equipped with a light float (such as less than 1g of lead) to avoid excessive weight of the wire group affecting the signal.
Thick line: A heavy lead sinker (such as consuming more than 5g of lead) is required to quickly sink to the bottom and stabilize the line group.
