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).
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.
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.
Data and metadata domains
Types of anchored fishing object (aFOB) (FOB.AFT)
Reference codes that model the types of anchored FOBs.
Types of anchored fishing activity types (aFOB) (FOB.AAT)
Reference codes that model the type of activities undertaken when interacting with an anchored FOB.
Type of fate (SPC.FTT)
Reference codes used to identify a given fate as indicating that the fish has been retained or discarded.
Raising (DTA.RA)
Reference codes modeling the level of raising applied to the data, and in particular if data:
- have been raised to the represent the total catches and effort in the year concerned (RT),
- have been raised but does not represent the total catches and effort in the year concerned (PR), or
- have not been raised at all (NR)
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.
