Fishing Net Mesh Size: Why It Matters

What Is Fishing Net Mesh Size?

Fishing net mesh size refers to the size of the opening between the netting strands. It is commonly specified according to the fishing method, target species, and local industry standards.

Different fishing applications require different mesh sizes, so there is no single mesh specification suitable for every type of fishing.

Why Is Mesh Size Important?

Targeting the Right Species

The mesh size should correspond to the size and characteristics of the target fish or marine species.

A suitable mesh allows target species to be retained while helping smaller fish pass through the net.

Improving Catch Selectivity

Mesh size plays an important role in catch selectivity. Choosing an appropriate specification can help fishermen better control the size of fish retained by the net.

This can be particularly important in commercial fishing operations where species and size regulations apply.

Maintaining Fishing Efficiency

An unsuitable mesh size may affect the performance of a fishing net.

The right mesh specification helps the net maintain its intended structure and function during fishing operations.

Mesh Size for Different Fishing Nets

Gill Nets

Gill nets require careful mesh selection because fish are captured according to their body size and shape.

The appropriate mesh size depends on the target species and local fishing requirements.

Trawl Nets

Trawl nets may use different mesh sizes in different sections of the net. The design can combine larger and smaller mesh areas according to the fishing method and target species.

Aquaculture Nets

Aquaculture netting requires mesh sizes suitable for the size of farmed fish and the purpose of the net.

The mesh should be small enough to contain the fish while allowing sufficient water flow.

Other Factors to Consider

Mesh size is important, but it should not be considered alone.

Customers should also consider:

Net material

Twine thickness

Net dimensions

Knotted or knotless construction

Target species

Water conditions

Local fishing regulations

These factors work together to determine the overall performance of a fishing net.

Choosing the Right Fishing Net

Before ordering a fishing net, it is useful to provide the supplier with the target species, fishing method, required mesh size, twine specification, net dimensions, and material requirements.

An experienced fishing net manufacturer can then recommend a suitable construction based on the intended application.

Conclusion

Mesh size is a key factor in fishing net selection. The correct specification can improve catch selectivity, support fishing efficiency, and help fishermen meet local requirements.

By considering mesh size together with material, twine thickness, net structure, and fishing conditions, customers can choose a more suitable fishing net for their specific application.
