The craft is fading — but less because of repair robots and more because the nets themselves are changing. Industrial fleets buy replaceable panels; aquaculture uses robotic inspection; the hand-mender's world shrinks to small fisheries and old skills.

Our AI replacement risk score — how we score jobs
Net mending is one of the oldest maritime crafts still practiced: reading a torn section of trawl or seine, cutting back to sound mesh, and rebuilding the diamond pattern with needle and twine so the repair fishes exactly like the original. A skilled mender counts meshes by eye, splices in panels, re-hangs netting to headropes and footropes, and knows that a bad repair changes how the gear fishes — a puckered patch can gap under load and lose a season's catch through a hole the size of a dinner plate.
The pressure comes from several directions at once. Industrial fleets increasingly treat netting as modular: damaged sections get swapped for factory-made panels rather than rebuilt stitch by stitch, and net lofts consolidate the remaining skilled work into a few service hubs. Machine-made netting is cheaper and more consistent than ever, tilting the repair-versus-replace math toward replace. In aquaculture — the growth side of fishing — ROVs and robotic crawlers now inspect and even patch cage nets underwater, and farms schedule net changes like tire rotations. Our 64 score reflects a craft being squeezed between cheap replacement and automated inspection rather than one being directly robotized.
What endures is the long tail. Small-boat fisheries, artisanal fleets, and remote ports can't ship a net to a service hub mid-season; someone on the dock who can rebuild a cod end overnight is worth real money when the fish are running. Custom gear work — modifying trawls for selectivity rules, building bycatch-reduction panels — is genuinely skilled and nowhere near automated. The trade won't vanish, but it's becoming what saddlery became: a small population of experts serving niches, not a dockside profession every port supports.
Automatability: our editorial assessment of current and near-term AI capability
The squeeze tightens through 2030. Aquaculture inspection is already going robotic, panel replacement keeps displacing stitch-level repair in industrial fleets, and net-loft consolidation continues. Hand-mending demand declines steadily rather than collapsing — small fisheries and custom gear work sustain a shrinking core of experts. By the early 2030s expect the trade to survive mainly as a specialty within gear shops and as a skill fishermen keep for themselves at sea.
In shrinking niches, yes. Industrial fleets increasingly swap factory-made panels instead of paying for stitch-level repair, but small-boat fisheries, remote ports, and custom gear work still pay for skilled hands — especially mid-season, when a rebuilt net overnight is worth far more than its invoice. The steady dockside living of past generations, though, is mostly gone.
In aquaculture, increasingly: ROVs and crawler robots inspect salmon-cage nets and some can apply patches underwater, replacing diver and manual inspection work. For capture-fishery gear like trawls and seines, robots don't mend — the economics killed the work differently, through cheap machine-made replacement panels that make hand repair unnecessary rather than automated.
Specialize or diversify. Custom gear modification — bycatch-reduction devices, selectivity panels driven by regulation — is skilled, growing, and unautomated. Net lofts serving aquaculture need people who understand both twine and cage systems. And the teaching niche is real: fleets still want crew who can make emergency repairs at sea, and someone has to train them.
Machine-made netting got cheap and consistent while skilled labor got scarce and expensive, flipping the repair-versus-replace math. Modular gear design accelerated it: damaged sections unclip and factory panels lace in, no master mender required. Repair survives where replacement logistics fail — at sea, in remote ports, and on custom gear no factory stocks.
