Deck TypeDecked and undecked vessels. Fresh fish in ice and/or frozen fish in blocks or boxes.OverviewLonglines can be operated from a dugout canoe or small rowing boat as well as from larger ocean-going vessels. Number of hooks and lines handled depends on the size of vessel, the degree of mechanisation and the size of the crew.Deck ArrangementThe main characteristics of a longline vessel that distinguish it from other fishing vessels are the rail roller, the longline hauler and in particular the setting chute on traditional longline vessels or the baiting and gear handling system on mechanised longliners. The wheelhouse can be situated aft or forward, but on larger vessels the bridge is generally placed aft. In typical arrangements the gear is hauled from the bow or from the side with a mechanical or hydraulic line hauler and the lines are set over the stern.EquipmentDeck EquipmentSmall scale longliners handling the gear by hand. The line is stored into baskets or tubs or by using a hand cranked line drum. On larger vessels automatic or semi-automatic systems are installed to bait the hooks and to shoot and haul the lines. In general such systems consists of rail roller, dehooker and hook cleaner, line hauler, hook separator, storage rack or drum. Different types of baiting machines makes the operation more efficient.Fish Detection EquipmentThe importance of fish finding equipment is relatively low in bottom longlining. Echosounders are mainly used to record the water depth and provide information about bottom substrate and configurations.Fishing GearBottom longlines.
