OverviewLift nets consist of a horizontal netting panel or a bag shaped like a parallelepiped, pyramid or cone with the opening facing upwards. These gears comprise the bag nets ('basnig') and the blanket nets. Often, depending on target species the catching process is supported by lights (in cases, a series of powerful ones) or simply some bait.Handling EquipmentLift nets are hauled out by hand or mechanically. For operating a large lift net and maintain it open, several long poles off one or the two sides of the boat are, in general, necessary. A number of pulleys and/or small winches for letting the lift net to dip, then for the hauling of it.Vessel Overview Lift netters.Fish OperationAfter having been left soaking at the required depth, for some time, the net is lifted off the water, by hand or mechanically, from the shore, from one or more boats. The fish are attracted by lights or bait.Target SpeciesSmall pelagic speciesWater Area OverviewAll over the world.Gear EnvironmentLift nets are operated from the surface in the upper water column, at sea or in inland waters.ImpactsSpecies The unexpected bycatch rates is, in general, low. However, when lights are used more species than expected are often attracted (e.g. cephalopods).
