Experimental Monofilament Gillnet FEX-01

— Scientific Sampling Net for Fish Studies

Product Description

The FEX-01 experimental monofilament gillnet is the professional standard for ichthyological sampling. It is also designed for fish population studies. This scientific net measures 150 feet (45.7 m), providing full coverage of all size classes thanks to its six progressive multi-mesh panels.

A Versatile Net for All Aquatic Environments

The FEX-01 can be deployed in lakes, rivers, estuaries, or at sea. It stands out for its robust construction and low visibility in water. This makes it ideal for non-lethal scientific fish capture for research purposes.

For over 50 years, our Canadian expertise has been recognized by fisheries research institutions. Fisheries departments and field teams worldwide also rely on our products.

Technical Specifications of the FEX-01 Gillnet

Main Dimensions

• Total length: 150 feet (45.7 m)
• Depth: 6 feet 6 inches (2 m)
• Number of panels: 6 × 25 feet

Progressive Mesh Size Sequence

The FEX-01 integrates six panels with different mesh sizes. This progressive sequence allows simultaneous capture of multiple size classes in a single sampling set.

Rigging and Assembly

The net is equipped with an integrated float line and lead line, ensuring optimal vertical opening under all conditions. The net is hung at a 55% hanging ratio for maximum capture efficiency.

High-Performance Materials

Each component is carefully selected to ensure durability and discretion:

• Netting: High-tenacity monofilament nylon — low visibility, high abrasion resistance
• Rigging: High-quality float line and lead line
• Twine: Braided nylon #18
• Assembly: Hand-sewn, panel by panel

Available Colors

• Monofilament: Transparent — optimal invisibility underwater
• Multifilament: White — custom dyeing available (+10%)

Applications and Uses of the FEX-01 Scientific Gillnet

Main Application Areas

The FEX-01 is primarily designed for aquatic fieldwork in biology. It is suitable for:

• Freshwater and marine fish surveys
• Stock assessment: age classes, size distribution, maturity stages
• Aquatic biodiversity studies and indicator species monitoring
• Environmental monitoring in lakes, rivers, and estuaries
• Academic and government fisheries research
• Standardized experimental fishing following DFO and Quebec MRNF protocols

Important Field Instruction

To minimize fish mortality, the net must be checked several times per day. This precaution also ensures high-quality biological data collection.
