Do you know that low-quality trawl twine can reduce fishing efficiency and even cause significant losses for fishermen? In the fisheries industry, choosing the right trawl twine not only increases catch yields but also extends the lifespan of fishing gear and reduces repair costs. So, which type of trawl twine is durable, high-strength, and best suited for different fishing methods? Let’s explore the key factors for selecting optimal trawl twine to enhance fishing efficiency with SIAM Brothers Vietnam in the article below!
1. What is Trawl Twine?
Trawl twine is a specialized type of fiber, commonly made from materials such as PE (Polyethylene), PP (Polypropylene), or Nylon. It features high durability, excellent tensile strength, and strong resistance to saltwater corrosion. Due to its robustness, trawl twine is widely used in crafting trawl nets, seine nets, and various other fishing gear.

The Crucial Role of Trawl Twine in the Fishing Industry
If fishing nets are considered the "main weapon" of fishermen, then trawl twine is the "foundation" that determines net quality. High-quality trawl twine not only provides the right elasticity but also minimizes net tearing, enhances fish retention, and ultimately improves fishing efficiency.
Key Characteristics of High-Quality Trawl Twine
- High durability: Capable of withstanding strong tension without breaking during operation.
- Abrasion resistance: Essential for offshore fishing, where nets are constantly exposed to seawater.
- Optimal elasticity: Helps nets retain fish without excessive contraction.
- Water resistance: Prevents moisture absorption, which can make nets heavier and affect performance.

2. Criteria for Choosing the Right Trawl Twine for Fishing
2.1. Durability & Tensile Strength
Trawl twine must be strong enough to withstand water currents and the force of fish schools. When selecting twine, consider:
- Durable materials: PE, PP, or Nylon twines are stronger than conventional options.
- High tensile strength: Ensures the net remains intact during operations.
2.2. Abrasion & Environmental Resistance
Saltwater is highly corrosive, so trawl twine must have excellent wear resistance.
- Saltwater resistance: High-quality twine resists seawater damage, preventing brittleness and breakage.
- Heat & UV resistance: Exposure to sunlight accelerates aging; UV-resistant twine extends longevity.
2.3. Optimal Elasticity
Trawl twine should offer flexibility without excessive stretch to maintain effective net performance.
- Firm yet flexible: Some twines are overly elastic, leading to deformation under force.
- Stable net structure: Prevents mesh shrinkage or expansion over time.

2.4 Weight & Water Absorption
Fishermen prefer lightweight trawl twine that remains durable for easier handling.
- Proper weight: Overly heavy nets can reduce efficiency and increase fuel consumption.
- Water-resistant: Prevents moisture absorption, reducing unnecessary weight during use.
2.5 Price & Trusted Brands
The most expensive trawl twine is not always the best option. Consider:
- Certified quality from reputable suppliers.
- User feedback from experienced fishermen.

4. Expert Tips for Choosing the Right Trawl Twine for Maximum Fishing Efficiency
4.1. Selecting the Right Trawl Twine Material
Each type of trawl twine has unique characteristics. Choose based on your fishing conditions:
- PE Trawl Twine: High tensile strength, excellent abrasion resistance, ideal for offshore fishing.
- Nylon Trawl Twine: High elasticity, preventing net shrinkage when hauling fish.
- PP Trawl Twine: Lightweight and cost-effective, best suited for inshore fishing.
Pro Tip: If durability and long-term use are your priorities, opt for PE or Nylon rather than PP.
4.2. Determining the Right Thickness & Tensile Strength
A thicker twine is not always better—it must match your fishing gear:
- Trawl nets, purse seines: Require high tensile strength to prevent excessive stretching.
- Gill nets, trap nets: Should have moderate elasticity to effectively retain fish.
Pro Tip: Always check the breaking strength specifications before purchasing to ensure compatibility with your fishing needs.
4.3. Prioritizing Abrasion-Resistant Trawl Twine
The saltwater environment is highly corrosive, so choose twine with:
- UV resistance – Prevents fiber brittleness and breakage under sunlight exposure.
- Excellent water resistance – Minimizes water absorption to prevent excess weight.
- Saltwater corrosion resistance – Ensures long-lasting durability of your fishing nets.
Pro Tip: Look for protective coatings on the twine—this is a key factor in extending the lifespan of your fishing gear.
4.4. Choosing a Reliable Trawl Twine Supplier
Not all suppliers provide high-quality twine. Consider these factors before purchasing:
- Opt for brands with years of experience in the fishing industry.
- Prioritize products with certified quality for proven durability.
- Read customer reviews from other fishermen to avoid low-quality purchases.
Pro Tip: Contact manufacturers or major distributors directly for better warranty policies.
4.5. Buying in the Right Quantity to Save Costs
Purchasing in bulk can save costs, but avoid overstocking without testing the quality first.
- Start with a small order to evaluate durability.
- Take advantage of supplier promotions to optimize expenses.
- Store twine properly to prevent damage before use.
Pro Tip: If you plan for long-term use, order in bulk to get better pricing and ensure a stable supply.
5. FAQ – Common Questions About Trawl Twine
