Fishing gears may be lost into the seas because of rough climatic conditions, damages of
the gear, entanglement with bottom obstructions or dragged away by other fishing vessels or
ships etc. These lost gears designated as abandoned, lost or otherwise discarded fishing
gears (ALDFG) contributes to species mortality by continuing to entangle and kill fishes and
other endangered/threatened species such as turtles, birds and mammals, a phenomenon referred
to as ghost fishing. Passive gears like traps, gillnets may catch fish for several months or even
years after they are lost. Locating ALDFG will be helpful to understand the fate and transport of
lost fishing gear and to remove them from marine waters, thus eliminating its harmful impacts to
species and habitats. Present study was undertaken for evidences of fishing gear losses and ghost
fishing from selected areas of Indian waters. Underwater investigation by scuba diving were
conducted at Enayam, Tamil Nadu & Vizhinjam coast of Kerala. About 33kg lost gears were
recovered by scanning an area of 700m2
seabottom at Enayam. Six types of lost gears were
retrieved in which Nylon monofilament gillnet panels (47.3%) were the predominant gear types
followed by pieces of trawl codends , parts of long lines, ropes , traps , and squid jigs. Retrieved
traps contained Molluscs, Arthropods, Echinoderms, Annelids and Cnidarians, Poriferans at
various degrees of decomposition. From Vizhinjam coast of Kerala, gillnet webbings and ropes were recovered. This baseline information will be useful to understand the scale and distribution
of ALDFG and identification of the hotspot areas of gear losses.
