Administrative and geospatial domains
Countries (ADM.COU)
Reference codes modeling the flag / reporting country submitting a dataset to the IOTC Secretariat.
IOTC main areas (GIS.IOTC.MA)
Reference codes modelling the two main areas in which the IOTC area of competence is split (western / eastern IOTC area, roughly coinciding with FAO areas F51 and F57).
Fisheries and fishing technologies domains
Fisheries (FIS)
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).
Catch units (FIA.CU)
Reference codes that model the units used to report the level of catches / discards of a given species, further stratified by the specific criteria characterizing each reporting form.
Biological and morphometrics domains
All species (SPC.ALL)
Reference codes modeling the species interacting with the fisheries as:
- target species (retained or discarded)
- bycatch species (retained or discarded)
- sampled individuals
- etc.
These codelists are subsets of the entries in the ASFIS list of species for fishery statistics purposes, from which they inherit the alphabetic codes, English, French and scientific names, as well as the family and order, and add the species category (in the IOTC sense), the IUCN status (retrieved from the IUCN red list of endangered species) and other characteristics of each entry such as their status of single species / species aggregate, bait species, SSI species, IOTC species.
Reasons for discarding (SPC.FTE.DI)
Reference codes that model the reasons why aquatic creatures caught by the fishery are then discarded at sea.
Individual conditions (SPC.CN)
Reference codes modeling the conditions (at capture / at release) of individual aquatic creatures being discarded at sea or measured.
Data and metadata domains
Data types (DTA.TY)
Reference codes modeling the type of statistics provided through a specific form, and in particular if these are:
- preliminary if the statistics were estimated by using some information from the fishery and year concerned, and the data reported are likely to change in the future as more information become available; or
- final if the statistics were estimated by using the complete set of data from the fishery and year concerned, and the data reported are unlikely to change in the future.
Data raising (DTA.RA)
Reference codes modeling the level of raising applied to the data (raised to totals / not raised to totals / unknown).
Discarded catches data sources (DTA.SRC.DI)
Reference codes modeling the source of the data provided through the discards data form.
Discarded catches data processings (DTA.PRO.DI)
Reference codes modeling the processing applied to the data provided through the discards data form.
Coverage types (DTA.COV.TY)
Reference codes modeling the type of coverage for the raw information used to obtain the data provided through a specific form.
