Investing in aquaculture netting starts with understanding the needs of your farming system. Price and product photographs are useful starting points, but a purchase also requires clear specifications, an installation plan and an agreed scope of supply. Preparing this information helps you discuss quotations and check the product against the requirements agreed with your supplier.
In this article, join SIAM BROTHERS VIETNAM as we explore the key checks to make before investing in aquaculture netting, from identifying the product to preparing the information needed for a useful consultation.

Aquaculture netting is used to form or divide spaces for holding farmed aquatic animals in an appropriate farming system. Before requesting a quotation, describe where the net will be used. A cage net bag, a surrounding net panel and a top cover serve different positions within a system. Identifying the intended position helps the supplier understand what you are asking for and prevents confusion between items that may look similar in photographs.
The product introduced by SIAM Brothers Vietnam in this article is knotless netting in black or green. It should be distinguished from trawling nets used for catching fish and other aquatic animals. Specifications for a trawling net should not be transferred to a net intended for a farming application. Equally, colour and product name alone do not establish fibre material, mesh dimensions or performance. Ask for the specifications of the exact product being quoted and compare them with a physical sample before agreeing on an order. Use the sample and written specification together as your reference.

Before choosing aquaculture netting, prepare information about the species being farmed, the production stage and the expected size of the stock when it enters the system. State whether the installation is in a pond, lake, river or marine location, and describe the conditions recorded by the operator. This gives the supplier a specific application to assess instead of relying on a photograph of another installation. Include the operational tasks that matter to your team, such as inspecting, removing, cleaning and replacing the net.
For an existing cage, provide drawings or measurements of the parts requiring netting, an overall photograph and close-up images of attachment points. For a new installation, ask the adviser to explain how the finished net dimensions will be determined from the design. Do not assume that the outer dimensions of a floating structure are automatically the correct dimensions for the net order. Agreeing on these details early helps both parties describe the same requirement and makes later discussions about fabrication and installation more precise.

A quotation for aquaculture netting should identify the product clearly enough for both buyer and supplier to use the same reference. Ask for the mesh dimensions, the method used to measure them, the twine specification, the material and the finished dimensions. A number can be misunderstood if the two parties use different measurement methods. For the black knotless product introduced here, request a sample to examine its construction and surface. Do not infer additional performance characteristics from the black colour alone.
If your purchase requires particular strength, outdoor exposure performance or an expected service period, ask for documentation applying to that specific product and the relevant conditions. A general company certificate should not automatically be treated as evidence for every property of an individual net. Before placing a larger order, agree on a reference sample, the specification items to check and the process for addressing a delivery that differs from the confirmed requirements. These details also provide a clearer basis for comparing quotations with equivalent scopes.

When budgeting for aquaculture netting, establish whether the quotation covers the net alone or also includes fabrication, connecting ropes, accessories, transport and installation. Similar initial prices can cover different amounts of work. Compare the individual items and ask the supplier to identify exclusions. This is more useful than deciding which option costs less by looking only at the net price, without knowing what else must be purchased or arranged.
When installing aquaculture netting in an existing cage, discuss how the net will connect to the frame or floating structure, which edges require fabrication and how attachment points should be checked. Ask for instructions covering cleaning, storage after removal and the signs that indicate a need for repair or replacement. If an expected service period is proposed, request its basis and applicable conditions. An informed investment decision should provide enough detail to plan purchasing, installation and continued use. It should also make responsibilities clear so that the buyer understands which work is included and which tasks remain with the operator.

The product is knotless netting in black or green, introduced by SIAM Brothers Vietnam. Confirm the exact specifications during consultation and quotation.
They should not be transferred automatically. Trawling nets are used for catching aquatic animals. A farming application requires information for the specific product and use confirmed by the supplier.
This article does not establish a single mesh size for every farming system. Provide the species, stock size and system design, then request advice with an agreed mesh measurement method.
Those properties cannot be established from colour alone. Check the documentation for the specific product and the stated conditions of use.
Provide the intended use, species, installation location, drawings or measurements, quantity and fabrication requirements. Include photographs of the installation where available.

Before investing in aquaculture netting, bring your requirements together in one brief. Describe the farming system, species, measurements, installation conditions and work you expect the supplier to provide. When reviewing advice, check the product name, sample, specification and items included in the quotation. Clarify missing information before ordering, particularly when fitting a net to an existing cage or requesting fabrication to a particular design. Keep the confirmed details together so they can be used when checking the delivery.
For the knotless product in black or green introduced in this article, discuss your actual requirements directly with the supplier before selecting a supply option. There is no need to guess dimensions from photographs or borrow specifications from a different type of net. A clear brief gives both parties a shared reference for consultation, quotation and handover. It also helps the operator keep a record of the product ordered and the guidance received for later inspection, maintenance discussions or a replacement request.
