Commercial Gill Nets: How Mesh Size, Twine And Net Construction Affect Fishing Performance

Commercial Gill Nets: How Mesh Size, Twine and Net Construction Affect Fishing Performance

Gill nets remain one of the most widely used passive fishing gears in commercial fisheries. A typical gill net consists of a wall of netting suspended in the water, with the mesh size selected according to the target species and local fishing regulations. Nylon monofilament and multifilament are among the most common materials used for commercial gill nets.

However, mesh size alone does not determine the performance of a gill net. The right combination of mesh size, twine construction, net depth, length, knot type and material is essential for achieving the required fishing performance and service life.

1. Mesh Size Should Match the Target Species

Mesh size is one of the most important specifications when ordering a gill net. Different target species require different mesh sizes because fish size and body shape directly affect how the fish interacts with the net.

For commercial fishing, mesh size should therefore be selected according to the target species, fishing area and applicable local regulations rather than simply choosing the largest or smallest available mesh. Research and fisheries guidance also show that mesh size and twine dimensions can influence the selectivity and fishing performance of gill nets.

At QinHo, we manufacture gill nets according to customers' specified mesh size, depth, length, twine specification and fishing application, allowing buyers to order netting according to their actual operating requirements.

2. Twine Material and Diameter Affect Strength and Durability

The second key factor is the twine.

Commercial gill nets are commonly produced from nylon monofilament, nylon multifilament, multi-monofilament and polyester, depending on the application and required performance.

A thinner twine can provide a softer and less visually conspicuous net, while a thicker twine generally provides greater breaking strength and resistance to mechanical damage. The selection therefore involves balancing fishing performance with durability.

For demanding commercial operations, the quality and consistency of the yarn are particularly important. A stable yarn diameter, uniform mesh and reliable knot strength help maintain consistent net performance during repeated fishing operations.

3. Knot Construction Matters

Different fishing applications require different knot constructions.

Single Knot (S/K) and Double Knot (D/K) are widely used configurations for fishing nets. Double-knot construction is particularly common in gill nets where reliable knot security is required. Other constructions, including knotless netting, are also available for specific fishing and aquaculture applications.

For commercial orders, we can manufacture netting according to the customer's required S/K, D/K, mesh shape, selvage and reinforcement configuration.

4. Length, Depth and Stretching Direction Must Be Clearly Defined

A professional fishing-net specification should not only state the mesh size and yarn.

The buyer should also clearly confirm:

Mesh size

Twine diameter or denier

Mesh depth (MD)

Net length

Stretching direction

Knot type

Top and bottom selvage

Reinforcement requirements

Color

Quantity per piece

For example, commercial gill nets may be supplied with lengthwise or depthwise stretching, depending on the fishing method and customer's established specifications.

This is particularly important for repeat orders. Keeping the same construction and dimensions helps fishermen maintain consistency between production batches.

5. Why Choose QinHo for Commercial Gill Nets?

As an experienced fishing-net supplier, QinHo provides customized commercial fishing nets for customers in different fishing markets worldwide.

Our production capability covers different materials, mesh sizes, twine specifications, knot constructions, colors, depths and lengths. We can also manufacture according to a customer's existing sample, specification sheet or previous supplier's specification, helping buyers maintain consistency when changing or adding a supplier.

Our advantages include:

Customized production according to exact fishing requirements

Consistent mesh size and net dimensions

High-quality nylon and polyester yarn options

S/K and D/K construction available
