Indian Ocean tuna - purse seine (SIOTI)

Primary tabs

Overview

The Sustainable Indian Ocean Tuna Initiative (SIOTI) was established in 2017 and comprises major purse seine fleets and canned tuna processors operating in the Indian Ocean. SIOTI successfully concluded the first phase of the FIP between 2017 and 2023 that resulted in all fleet partners being MSC-certified or in full assessment against the standard for skipjack tuna. The successful FIP partnership is, since 2023, now focusing its attention on fishery improvements for yellowfin and bigeye tuna, building on impactful interventions made in the first phase of the FIP while actioning others to ensure that the fishery for both species can achieve the MSC standard by 2028. Hence, the FIP has been rebranded as SIOTI.2, marking the FIP entering a second phase of implementation in 2023.

Target species: SIOTI.2 focuses on the purse seine fishery target species of yellowfin (Thunnus albacares) and bigeye tuna (Thunnus obesus

Fishing methods: The FIP encompasses the use of purse seine gear by large (>60 m LOA) specialist purse seine vessels. Sets by the vessels can be made on free schools of tuna or schools of tuna associated with floating objects

Fishing area: The fishery operates under the jurisdiction of the Indian Ocean Tuna Commission (IOTC) in FAO Statistical Areas 51 and 57

Fishing fleets: The SIOTI fleet comprises 27 purse seine vessels flagged to France, Italy, Mauritius, Seychelles and Spain.   

 

FIP Description 

The Sustainable Indian Ocean Tuna Initiative (SIOTI) was established in 2017 and comprises major purse seine fleets and canned tuna processors operating in the Indian Ocean.

FIP Objective(s) 
  • To enhance a successful industry collaboration that is making fishery improvements and promoting a transition to sustainable purse seine tuna fishing in the Indian Ocean by June 2028
  • To continue and build on actions aimed at rebuilding yellowfin and bigeye, securing ecosystem functioning and strengthening governance of the fishery by June 2028

Update 
The SIOTI FIP has made good progress in implementing its work plan since 2017 with all fleet partners now MSC-certified or in assessment for skipjack tuna (see links below). There is a need for SIOTI to continue actions for yellowfin and bigeye tuna, both of which are subject to rebuilding measures by the RFMO that require time to take effect on the stock. Progress in harvest strategy development for both species is at an advanced stage, with bigeye now benefitting from a management procedure (see relevant updates in the action tab). While several actions have been completed in the first phase of SIOTI (2017-2023), certain actions aimed at addressing principles 2 and 3 also require more time for completion, which has led SIOTI to develop a revised environmental workplan. Hence, SIOTI.2 constitutes an extended FIP that will focus on yellowfin and bigeye tuna. https://fisheries.msc.org/en/fisheries/echebastar-indian-ocean-purse-seine-skipjack-tuna/@@view https://fisheries.msc.org/en/fisheries/cfto-indian-ocean-purse-seine-skipjack-fishery/@@view https://fisheries.msc.org/en/fisheries/anabac-indian-ocean-purse-seine-skipjack-fishery/
