Tools of the Trade | Riblines
A net may be made of mesh, but the mesh isn't doing all the work.
Riblines are the heavy-duty lines that run lengthwise along a trawl net, providing strength and structure from the mouth of the net toward the codend.
As the net moves through the water and comes under load, riblines help support the net and maintain its shape. Think of them almost like the frame of the trawl, adding strength where it's needed while the surrounding mesh does its job.
Their size, material, and placement can vary depending on the design of the net, but their purpose is an important one: adding structure to a very large piece of fishing gear as it moves through the water.
It's another example of how a trawl isn't simply a big net. Every line, panel, and piece of mesh is designed to play a specific role in how the gear performs.
