Short communication: The effect of depth of operation and soaking time on catch rates in the experimental tuna longline fisheries in Lakshadweep Sea, India [PDF]

, 2016
Most of the marine fish landings from the Indian waters are from the fishing operations in the coastal shelf area, especially from the shallower region ranging from 5 to 100 m depth.
