Return back to the list of reference data domains.
A set of code lists modelling the IOTC fisheries concept and its components. The latter are not generally used within IOTC forms, and are kept here for reference only.
An ad-hoc classification derived from a combination of several factors (purpose, area of operation, vessel size category, gear, gear configuration, fishing mode and target species) that uniquely describe fishing practices for groups of vessels.
An interactive wizard to help CPCs identify the IOTC code for their fisheries (among those currently considered of relevance in the Indian Ocean).

See also: IOTC-2022-WPDCS18-13 to understand how IOTC fisheries are determined from a combination of:
The category each fishery belongs to (one among LONGLINE, SURFACE, and COASTAL, see also Res. 15/02)
An ad-hoc classification derived from a combination of the fishery’s:
An ad-hoc classification for the purposes of a fishery
An ad-hoc classification for the fishery’s areas of operation (consistent with the RAV requirements)
An ad-hoc classification for the LOA classes of the vessels participating to a fishery (consistent with the RAV requirements and extended to better classify semi-industrial activities)
An ad-hoc classification to model the group of gears commonly used in IOTC fisheries. These are mapped on the latest ISSCFG gear groups or on a subset of their included ISSCFG gears.
An ad-hoc classification to model the gear used to catch the fish. These are mapped on the latest ISSCFG gears.
Referenced in forms: 2FC
An ad-hoc classification to model the specific configuration of the gear used to catch the fish, whose possible values are determined by the specific gear selected among those available for the gear group.
The gear configurations associated to all valid combinations of gear and fishery type.
An ad-hoc classification to model the fishing mode used to catch the fish, whose possible values are determined by the specific gear selected among those available for the gear category.
The fishing modes associated to all valid combinations of gear and fishery type.
An ad-hoc classification to model the (group of) species that most accurately represent the target of the fishery.

Fishing boats are classified according to their shape and the purpose for which they were built. A boat that has been classified under a specific type shall not change over time, unless such boat undergoes major structural changes (e.g. significant changes in hull shape and / or size and/or material). For instance, the vessel type for stern trawlers whose decks have been modified for longlining or fiberglass longliners that have been modified for squid jigging will remain as beam trawlers and fiberglass longliners, respectively (if those modifications did not imply major changes in boat shape).
This code list includes several types of boat currently known to the IOTC: countries using types of boat other than those specified are encouraged to provide this information to the Secretariat.
Referenced in forms: 2FC
IOTC CPCs and other parties are encouraged to report vessel size categories in length (i.e., length overall or LOA, in metres) for their fisheries: fish carrying capacity, measured in tonnes or m3, as well as gross tonnage (GT / GRT) can be used alternatively when LOA is not available. IOTC CPCs should make every possible effort to classify their fleets according to the categories recorded in this code list and report this information to the Secretariat.
