Comprehensive investigation on status and changes in fishing practices of migratory fishermen in Cochin backwaters, Kerala was conducted for a period of one year from June 2016 to May 2017. Identified predominant habitats of migratory fishermen viz., Nettor, Vypin and Mulavukadu were identified. Data on type of crafts, gears, and fish catch composition obtained from these gears were collected fortnightly from these study areas. The coracle and bottom set gillnet were the predominant raft and fishing gear used by the migratory fishermen of the study areas. Technical details of both raft and gears were recorded. Different type of bottom set gillnets used by the fishermen were locally known as ‘Njanduvala’ with mesh size of 90 to 150mm, ‘Karimeenvala’ with 50 mm and 70 mm and for ‘Koori vala’ having mesh size of 40 to 60mm. The twine thickness for all these nets was 0.1 to 0.2 mm. The Hanging co-efficient was 0.4-0.6 for both ‘Njanduvala’, and ‘Karimeenvala while it was 0.5 to 0.6 for ‘Koori vala’. Main catch from the former two gears were crabs and targeting pearl spot (Etroplus suratensis) and catfishes from the later one.
