Net haulers are usually used to set and haul driftnets, with a drifter capstan on the forepart of the vessel. In developing countries most nets are hauled by hand. The mesh size of the gillnets is very effective at selecting or regulating the size of fish caught. The drift net has a low fuel/fish energy consumption compared to other fishing gear.
Fishing nets, cod traps, and sails would be dipped into a barking pot filled with a solution of bark and other materials. [5] The use of bark mixtures for the preservation of nets was brought over by English migrant fishermen during the 17th century; Aaron Thomas described the vessel used for making this bark mixture in his 1794-1795 journal of ...
A Japanese glass fishing float. Glass floats were used by fishermen in many parts of the world to keep their fishing nets, as well as longlines or droplines, afloat.. Large groups of fishnets strung together, sometimes 50 miles (80 km) long, were set adrift in the ocean and supported near the surface by hollow glass balls or cylinders containing air to give them buoyancy.
A seine is a large fishing net that may be arranged in a number of different ways. In purse seine fishing the net hangs vertically in the water by attaching weights along the bottom edge and floats along the top. A simple and commonly used fishing technique is with beach seine, where the seine net is operated from the shore.
A fish wheel is a device for catching fish which operates much as a water-powered mill wheel. A wheel complete with baskets and paddles is attached to a floating dock. The wheel rotates due to the current of the stream it is placed into. The baskets on the wheel capture fish traveling upstream. The fish caught in the baskets fall into a holding ...
Similar to a gillnet, the tangle net, or tooth net, is a type of nylon fishing net. Left in the water for no more than two days, and allowing bycatch to be released alive, this net is considered to be less harmful that other nets. The tangle net is used in the Philippines by commercial fishermen, as well as by the scientific community. When ...
A Norwegian fisherman caught a US submarine in his nets this week. The USS Virginia's propellers got tangled in the nets, reports say, dragging them out to sea.
The cod end is the trailing end of the net where fish are finally "caught". The size of mesh in the cod end is a determinant of the size of fish which the net catches. Consequently, regulation of mesh size is a common way of managing mortality of juvenile fishes in trawl nets.
