Using net sections made from threads with different dyeing properties, one dyeing step creates widthwise color variation while cutting labor and cost.

Embedded sensors and timed emitter signals reconstruct 3D fishery net shape, helping prevent entanglement, damage, and equipment collisions.

A zinc-aluminum coating on high-strength steel wire extends mesh service life in harsh climates while reducing maintenance and repair needs.

Separate cross-point connectors create continuous non-elastic load paths in fish cage bags, reducing wear, rupture, and fish escape.

Distributed carabiner latches secure net patches quickly while spreading load across yarns to avoid folds, stress points, and further tearing.

A zinc-aluminum coating on high-tensile wire netting resists salt and sulfur corrosion, extending service life and cutting maintenance.

A releasable transport bag moves catch from deployed trawls to the vessel, cutting idle time, gear wear, and catch damage.

Torsion-free bending preserves high-strength steel wire strength, reducing breakage and shape errors in resilient braided wire mesh.

A dual-layer oxide on copper alloy aquaculture wire balances corrosion resistance with antifouling while reducing metal release in seawater.

Convex-concave rib edges smooth water flow on a trawl door, cutting turbulence and drag while improving stability and fish entry.

A mesh cylinder and drawstring keep buoy lines submerged until retrieval, preventing whale entanglement while enabling reliable trap recovery.

Sensor-guided cable tensioners keep aquaculture nets within target tension to prevent escapes and detect cable failures in harsh offshore conditions.

Thermal neutralization and automated collection remove invasive sun coral from subsea structures without diver exposure, reducing risk and delay.

A sliding horn hook applies upward force to the cast net central horn, easing braille line tension so snagged nets can be freed without entering the water.

Magnetic slider retention keeps a tapered bowfishing arrow engaged with the bowstring in wet conditions while supporting stable launch and retrieval.

A sensor-triggered piston blade cuts fish free from gill nets and punctures the gill to start bleeding with minimal net damage.

A bottom-stowed buoy and coiled line release on demand, avoiding whale entanglement while keeping trap recovery practical with standard gear.

Sensor-driven mode switching keeps a trawl net on setpoint as bathymetry changes, reducing bottom contact, fuel use, and bycatch.

Predictive control combines sensor feedback, tow angle modeling, and setpoints to keep trawl nets off the seabed and cut fuel use.

A programmed release cam keeps trap lines submerged until retrieval time, cutting whale entanglement risk without disrupting fishing operations.

Grip-hooks and a locking mechanism let divers or ROVs patch fish farm net holes and rifts quickly while reducing stress on nets and fish.

A parallel horn line lifts the central horn to relieve braille-line tension and free snagged cast nets without entering the water.

An embedded horn line pulls the central horn to relieve braille-line tension and free snagged cast nets without entering the water.

A detachable handle and rim let this fly-fishing net break down into compact parts for easier backpack transport without losing landing function.

A transmission shaft drives bidirectional wing plates to replace passive rope-length control with active krill trawl depth adjustment.
