| genuine link | |
| It is a requirement in international law (LOS Convention, Art. 91; High Seas Convention, Art. 5) that there exists a genuine link between a State and a vessel flying its flag. However, there is no defintion of genuine link in international law - attempts to define it have generally failed because of the negative economic implications for the so-called flag-of-convenience States - and the requirement is not widely observed in the practice of States. | |
| geographic information system (GIS) | |
| A computer system for storage, analysis and retrieval of information in which all data are spatially referenced by their geographic coordinates. In addition to primary data, a GIS can be used to calculate derived values such as yield data. | |

| ghost fishing | |
| The term used when lost or abandoned nets continue to take marine life in the sea after they have been lost or abandoned. The extent of damage caused by such an event and the length of time these nets continue to fish in the water cannot easily be calculated, but it is thought to be an important factor with some driftnets. | |
| gillnet IMAGE | |||||
| These nets consist of a panel
or panels of net held vertically in the water-column. The fish are caught by their gills
in the net. According to their design, ballasting and buoyance, these nets may be used to
fish on the surface, in midwater or at the bottom. See also:

| groundfish | |
| A species or group of fish that spends most of its life on or near the sea floor. | |
| growth overfishing | |
| The rate of fishing, as indicated by an equilibrium yield-per-recruit curve, greater than which the losses in weight from total mortality exceed the gain in weight due to growth. This point is defined as Fmax. | |
