About circular netting

Types of Circular Netting

For balance and stability during flight, circular netting is used. Opt for expansive nets with large openings for catching deep-swimming species like tuna, mojarra, and sardines.

Circular Net 1.5 m

The measurement of this circular net states its diameter; a net of 1.5 m will have an opening diameter of 1.5 meters. Withstood by agriculture, this net is flexible, strong, and drop-resistant as it is made of polyethylene. Also, nets of this size can be moved comfortably within small spaces. Its round configuration allows even distribution and acts like a trap when pulled from the water surface. The netting material of choice for a long life and numerous catch is corrosion-resistant. Different wire strengths can be chosen depending on the required durability.

Circular Net with Floats

To keep the net atop water, circular nets with floats integrate buoyant elements on the perimeter. A circular fishing net with floats is specifically formed for catching fish. The floats that are attached to the net's top edge cause the net to hang vertically in the shape of a cone. This style of net is suited for capturing pelagic fish that swim near the ocean surface. Lightweight foam or plastic is used to construct the floats, which can be adjusted to the net's diameter. The expanded area causes an increase in the catch when the net is deployed.

Circular Fishing Net

Around the world, fishermen use circular nets because they are so effective at collecting fish. It is a common source of food in many countries because it helps catch food fish. The net is thrown over fishstacks and falls around them like a trap. It is versatile, durable, and easy to use, making it especially popular among small fishermen and coastal countries. Integration of weights and floats in the net to keep it submerged or afloat enhances the catch capability of the net.

Circular Net with Weights

To keep the bottom edge of the net's pocket level with water, circular nets with weights embed sinkers or weights around the net's periphery. Weighted fishing nets are effective for surface and mid-water fish.

Durability and Materials of Circular Netting

Approximate lifespan, under the right use, of circular netting can be called nett durability. This is a crucial consideration because it affects efficiency and cost. The material of the netting and the way it is put to use determine the longevity of the net and what it's meant to catch.

Durability Based on Fishing Environment

Saltwater conditions are harder and shorten a net's life, while freshwater extends it. Fishing net prices rise when nets are made for harsh chemical, temperature, and debris environments.

Durability Based on Target Catch

The net's strength and structure should be increased if the target fish has sharp teeth, strong tails, or is large. Nets used for delicate fish require careful net selection to avoid net handling.

Net Material

Nylon materials have high tensile strength with minimal wear. However, by absorbing UV light within its structure over time, exposure to sunlight degrades nylon fishnets. While strong, polyethylene is less prone to UV damage.

Low temperatures cause net materials to become brittle. Fishing nets near freezing waters must be of impact-resistant materials. Heavy frames and tools, wearoses, or ropes designated for fishing can damage nets.

Although nets come in varying diameters and mesh sizes, conventional net materials account for the highest fish catch. Monofilament nets are hardest to see, hence more fish can be trapped by them. Multifilament nets are thicker than monofilament nets, which lay indiscriminately over sensitive fish to prevent damage.

Less entangling occurs with knotless nets, making them suitable for soft-skinned fish. No knots do not equally distribute the weight within the net, decreasing the catch.

Target Species

Insects, larvae, and eggs are caught by small-meshed nets while larger mesh nets catch fish and crustaceans. Pelagic and small tuna, mackerel, sardines, and anchovies are collected by round purse nets as they are powerful and robust. Weak or damaged nets and extra-small fish combined with circular nets for aquaculture are unsuitable.

Commercial value and uses of Circular Netting

The circular nets are one of the most reasonably priced yet durable and versatile nets used for fishing. This is usually a round neting gear on the surface of the water used to trap schools of fish, such as sardines, tuna, anchovies, and mackerel.

Catch of the Day

Target catch of circular nets can be pelagic or demersal fish.

Bycatch or Non-target Species

Unfortunately, using circular nets, people also unintentionally catch non-target fish. Hammerhead sharks, school sharks, sea turtles, etc., also stand the risk of being trapped by these nets.

Intricate Net Designs

To encourage a more effective fish catch, circular nets have inward- or outward-tilted mesh, escape holes for juvenile fish, or selectively permeable mesh sizes.

Live Fish Transport

Fish transported over short distances within aquatic environments use circular nets. Circular nets lift fish delicately to minimize stress and mortality.

Aquaculture Stocking and Harvesting

Fish farming uses circular nets to stock fingerlings or harvest mature fish. Fish within the circular nets during harvesting have equal access to food and space, enabling them to grow healthy.

Rehabilitation of Declining Fish Stocks

The circular nets are designed to be less destructive to fragile fish species like eels and flatfish and their habitats. Releasing bycatch enables the population of overexploited fish to recover.

Marine Research and Monitoring

Scientists working on conservation or population estimation use circular nets for fish collection. Catching fish for tagging, relocation, or study purposes is less harmful with circular nets.

Flexible frameworks with varying mesh sizes and materials are what makes circular netting valued commercially. The future of circular netting is uncertain as it contributes to marine debris through mindless discard and lacks a circular economy.

How to Choose Circular Netting

Some key factors help choose the the best circular nets for a particular use.

  • Mesh Size

    Catch the desired fish by choosing a mesh size adequate to allow small fish to pass through. Nets meant for small fish like sardines require smaller mesh than those for big fish like tuna.

  • Net Material

    Fishnets for sale can be made from different textiles, including polyethylene (PE) and nylon). Polyethylene is commonly used for aquaculture and commercial fishing because it is relatively easier to process. Tougher and more resilient than monofilament, multifilament nets provide better visibility in water.

  • Net Depth

    Circular nets are available in multiple depths depending on how deep the target fish school is in the water column. Fish found near the sea surface need a shallow net, while those found in mid-water or at the bottom require a deeper net.

  • Hanging Ratio

    A modification of the mesh shape is a consequence of the hanging ratio. This elicits better or worse catches depending on the ratio. Smaller ratios formed for schooling fish with strong schooling tendencies are preferred.

  • Nets with Weights and Floats

    For catch near the ocean surface, nets and circular fishing traps are meant to be equipped with weights and floats. In contrast, circular nets with weights alone are designed for mid-water or bottom fishing.

  • Fishing Conditions

    Circular netting products should be chosen based on the fishing conditions. Nets designed for rough sea conditions or strong currents should be more resilient than those used in calm or sheltered waters.

  • Target Species

    Choose the circular net that is better suited to the defined characteristics of the target fish species. Caught food fish for practice or aqua farming and fish portioned for scientific studies and relocation require different nets, as do the circular nets made for small and big fish.

Q&A

What is a circular netting?

A circular net is a net that is shaped like a circle and is used in fishing to catch different types of fish. It is thrown over fish in schools and, when pulled in, traps the fish inside.

What is the function of a circular net?

The job of a circular net is to catch fish by trapping them within the netting. It catches the fish that attempts to match the net mesh size.

Which netting is best for fishing?

Mesh size, net material, depth, hanging ratio, and fishing conditions determine the best circular net for any target fish. Fishnets for sale are the result of all parameters considered for range and fishing environment.

Are fishnet circles effective?

For their schooling characteristics, maximizing the catch, and being cost-effective, circular nets are effective for their purpose.

How do fish nets impact the environment?

Some net types have favorable effects, like supporting fish and marine life recovery and research, while others have adverse effects like entangling protected species, marine mammals, and sea turtles, or becoming marine debris which contributes to pollution.
