Term	Meanings
GBRMPA	Great Barrier Reef Marine Parks Authority
Gear restriction	A type of input control used as a management tool whereby the amount and/or type of fishing gear used by fishers in a particular fishery is restricted by law.
Gear unit	A standard measure to manage fisheries (e.g. one gear unit = 1,000 metres of net).
Gillnet, monofilament gillnet	A type of passive fishing gear consisting of panels of net held vertically in the water column, either in contact with the seabed or suspended from the sea surface, such that fish attempting to swim through them are entangled. The mesh size of the net determines the size range of fish caught, as smaller fish are able to swim through the meshes. Fish are held behind the gill plate as the head passes through.
GIS	Geographic Information System
Global positioning system	A device which uses satellite signals to accurately determine a vessel's position and course.
GPS	Global Positioning System
Grow-out	The period in which juveniles grow to market size
Growth overfishing	Occurs when too many small fish are being harvested from a particular fishery, such that a restraint on them being caught would ultimately lead to an overall increase in yield from the fishery.
GVP	Gross Value of Production
Handline	Hand-held lines of various types that are used widely throughout Australia to catch fish.
Haul net	A piece of net used similarly to a beach seine net but operated from a small boat in shallow water (less than 5 m). The net is used to encircle the fish and then hand-hauled while the vessel is stationery. The meshes used are regulated to select specific sizes of a species. See seine net.
HWM	High Water Mark
IDU	Industry Development Unit
IFAAC	Integrated Fisheries Allocation Advisory Committee
IFM	Integrated Fisheries Management
IMO	International Maritime Organisation
Incidental catch (by-product)	Retained catch which is not the primary target of a fishing operation.
Input controls	Controls on fishing to limit catches; e.g. size of boats, gear type and amount, pot numbers, seasonal closures or limitations on the number of licences (cf. output controls).
Inshore waters	The near coastal waters extending from the coastline, estuaries or straight baseline out to three nautical miles, which is the boundary of the State and Territory waters. This term also refers to the waters of the shallower part of the Continental Shelf.
Invertebrates	Animals without a backbone, for example shellfish, worms, jellyfish, sponges, seastars and corals.
IOTC	Indian Ocean Tuna Commission
ITE	Individual Transferable Effort
ITQ	Individual Transferable Quota
Joint authority	An Offshore Constitutional Settlement (OCS) arrangement whereby a fishery is managed jointly by the Commonwealth and one or more States under a single (Commonwealth or State) jurisdiction.
Joint venture	Collaborative fishing operation, often involving two companies from different countries.
