Wide and tall net dropped from a boat and manoeuvred so as to surround the school and locking the fish in a purse.


Net drawn behind one or two boats and comprising a conical body, previously extended by "wings", terminating in a sac in which the fish are retained.

Gill nets

A single net wall kept more or less vertical by floats and a weighted ground line in areas where schools travel through. The fish are caught (gilled) in the net as a result of their own movement. The trammel net is a similar technique, but made up of three overlapping nets of different mesh sizes. Both are passive fishing gear.


Large vertical nets set so as to intersect the migratory routes of the tuna, placed permanently in the water along the coast, with a system of channels, barriers and chambers that the fish can enter freely but from which they cannot escape.



Made up of a strong and long main line to which are attached branch lines at regular intervals ending in a baited hook. Depending on where in the water column the longline is set, surface or bottom, floats or weights are used to achieve buoyancy or sinking of the gear.

Pole and line fishing

Uses live bait on a line (sardines, mackerel, horse mackerel, etc.), attached to a pole of variable size and shape, and the jump technique, which is when the fish bites the bait and is pulled aboard in a single movement thus making it jump.


Traps are frames with various forms, into which the prey are attracted by bait or simply because they seek shelter. They may be used alone or connected to a line at regular intervals, anchored and with buoys marking their location.

The cage traps are metal structures covered by a net, with an opening through which the prey enters and a lid at the other end through which the captured species are removed.

The shelter traps (pots) are clay or plastic pots, used for catching octopus, which enter the trap to seek shelter.
