Experimental Monofilament Net FEX-02 — The Reference Tool for Ichthyological Sampling

Designed for biologists, ecologists, and scientific fisheries professionals, the Experimental Monofilament Net FEX-02 is a research gillnet combining scientific precision, durability, and exceptional versatility. With its 6 panels of progressive mesh sizes ranging from 1″ to 3½”, it effectively captures a wide diversity of species and size classes across all aquatic environments.

FEX-02 Technical Specifications

Distinctive Features of the FEX-02 Monofilament

Multi-Panel Design with Progressive Mesh Sizes

The FEX-02 is structured into 6 distinct panels, each offering a different mesh size (1″, 1½”, 2″, 2½”, 3″, 3½”). This progressive design allows for the simultaneous capture of different size classes in a single deployment, optimizing the efficiency of faunal surveys and reducing the number of field trips required.

Transparent Monofilament — Maximum Discretion and Efficiency

Made from transparent monofilament, the FEX-02 is virtually invisible underwater, reducing fish wariness and significantly increasing catch rates. This lightweight, durable, and rot-resistant material is ideal for studies in clear waters, lakes, rivers, and estuarine environments.

Professional Hanging at 55% Ratio

Each panel is hand-sewn and rigged at a hanging ratio of 55%, ensuring proper pocket formation and optimal net positioning whether deployed at the surface, mid-water, or on the bottom.

Integrated Float Line / Lead Line System

The floating line maintains the net’s vertical position, while the calibrated lead line ensures bottom stability in varying hydrodynamic conditions. This dual-line system is adapted for moderate currents and calm water bodies.

Scientific and Professional Applications

The FEX-02 Experimental Gillnet is designed for the following uses:

• Ichthyological surveys in lakes, rivers, estuaries, and coastal marine zones
• Size and age class distribution studies within fish populations
• Assessment of sexual maturity and cohort recruitment
• Long-term monitoring of fish communities within environmental monitoring programs
• Impact studies related to human activities, climate change, or species introductions

  Scientific best practice: To minimize mortality of captured specimens, the net should be checked multiple times daily. The FEX-02 is designed for responsible use within mark-recapture protocols or controlled sampling programs.

Complete Experimental Net Range

To meet all sampling needs, we offer an extensive range of complementary experimental nets:

Using several models in combination allows full coverage of the target species’ size spectrum for comprehensive surveys.

Trammel Net Option — A Less Selective Alternative

For studies requiring very low selectivity, we also offer trammel nets composed of three layers of webbing. This system effectively captures fish from 8 cm to 1 meter, complete with floats and a leaded footrope. Trammel nets are custom-manufactured to your project specifications.

Custom Manufacturing

For over 50 years, we have been manufacturing scientific, commercial, and sport fishing nets recognized for their superior quality and longevity. Every net is handcrafted in our specialized workshop.

Customizable options:

• Custom dimensions (length, depth, number of panels)
• Mesh combinations adapted to your protocols
• Custom dyeing for multifilament nets (+10%)
• Specific rigging to meet your study requirements
