Return back to the list of reference data domains.

Species groups (SGR)

• Permalink
• Version: 1.0.0
• Last updated: 2023-05-12

All groups of species of relevance to the IOTC.

Species categories (SCA)

• Permalink
• Version: 1.0.0
• Last updated: 2023-05-12

All categories of species of relevance to the IOTC.

Species (SPC)

Reference codes modeling the species interacting with Indian Ocean fisheries as:

• target species (retained or discarded)
• non-target species (retained or discarded)
• sampled individuals
• etc.

These correspond to a subset of the entries currently found 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 (IUCN 2022. IUCN Red List of Threatened Species. Version 2022-2 <www.iucnredlist.org>) and other characteristics of each entry such as their status of single species / species aggregate, bait species, SSI species, IOTC species.

Species references are associated to a species group and to a species category through their SPECIES_GROUP_CODE and SPECIES_CATEGORY_CODE attributes, respectively.

All species (SPC.ALL)

• Permalink
• Version: 1.0.0

IOTC Species (SPC.IOTC)

• Permalink
• Version: 1.0.0
• Last updated: 2023-05-12

The subset of all species that is directly managed by the IOTC, as defined in Article 3 of the Agreement (Species and stocks):

“The species covered by this Agreement shall be those set out in Annex B. The term ‘stocks’ means the populations of such species which are located in the Area or migrate into or out of the Area”.

Target species (SPC.TAR)

• Permalink
• Version: 1.0.0
• Last updated: 2023-05-12

The list of species that are intentionally targeted by one or more Indian Ocean fishery for tuna and tuna-like species.

The definition of bycatch in the IOTC is that of “All species, other than the 16 species listed in Annex B of the IOTC Agreement, caught or interacted with by fisheries for tuna and tuna-like species in the IOTC area of competence”.

“A bycatch species includes those non-IOTC species which are:

1. retained (byproduct),
2. incidentally taken in a fishery and returned to the sea (discarded); or
3. incidentally affected by interacting with fishing equipment in the fishery, but not taken”.

Therefore, the target species listed here also include bycatch species, according to the definitions above.

Species of Special Interest - SSI (SPC.SSI)

• Permalink
• Version: 1.0.0
• Last updated: 2023-05-12

For the purpose of improving the voluntary collection of information on the post release mortality of discarded species of special interest, the Scientific Committee - at its 21^st session in 2018 - endorsed the list of species considered of special interest, as proposed by the ROS expert workshop.

This list is originally found in Appendix VIII of the WPDCS14 report, and further simplified in Appendix 6b of the SC21 report.

Currently, the list of species of special interest includes:

1. All marine turtles
2. All cetaceans
3. All seabirds
4. Designated shark species, and more specifically those species subject to a retention ban (i.e., whale sharks, oceanic whitetip shark, and thresher sharks)
5. Designated billfish species, and more specifically those included in Res. 18/05 (i.e., striped marlin, black marlin, blue marlin, and Indo-Pacific sailfish)
6. (added) All mobulid rays, as per para. 3 of IOTC Res. 19/03
