Species of
fish that live mostly in or near the bottom constitute the catch of an otter
trawl. These species include shrimps, slipmouths, goatfishes, groupers,
hairtails, snappers, croakers , whiting, lizard fishes, soles, eels, crabs,
nemipte-rids and other benthic fishes.
An otter trawl (galadgad) is a conical bagnet with a
mouth opening flanked on both sides by wings which are kept open by otter
boards/doors acting as kites, dragged/pulled to catch species of fish living in
or near the bottom of the sea.
This fishing gear is
operated during daytime or night time in waters of moderate depths, and some
distance from the shore. The trawl net is towed/dragged along the smooth bottom
of the sea by a power-propelled vessel. The other doors, which are connected to
the towing rope glide as kites stretching the wings and the mouth, is
vertically opened by floats on the headrope and sinkers on the ground rope.
When the gear is towed along, all the fishes encountered on its path are swept
into the cod net
