Abstract
Longline fishing is a fuel efficient and selective
fishing method with low environmental impact. The
longline fishing methods of Kerala, Tamil Nadu and
Andhra Pradesh are discussed in this paper, based
on the studies conducted during 2012-2013. Mechanized
vessels of LOA 9.5 to 20 m with 97-250 hp
engines are used for longline fishing in this region.
Fishing is normally multiday extending from 5 to
40 days. The longline vessel has a crew complement
of 6 to 15. Some of the vessels use mechanical or
hydraulic winches for hauling the line. The total
length of the main line ranged from 15 - 25 km.
Longline vessels target commercially important
high value species like tuna, marlin, sailfish,
seerfish, shark and rays. Structural and operational
changes in longline fishing which happened during
the last few decades have also been documented
