Preamble

ISSF is a global partnership among scientists, the tuna industry and the environmental non-governmental community whose mission is to undertake science-based initiatives for the long-term conservation and sustainable use of tuna stocks, reducing bycatch and promoting ecosystem health.
Since its inception, ISSF has adopted conservation measures and commitments to facilitate this mission with the intent that processors, traders, importers, transporters and others involved in the seafood industry will follow them to facilitate real and continuous improvement across global tuna stocks.
ISSF Participating Companies commit to conform to these conservation measures to improve the long-term health of tuna fisheries. They also must adhere to the ISSA Compliance PolicyAudit reports are published for all companies in aggregate as well as for individual companies.

Conservation Measures

1) RFMO Support

ISSF_CommitmentsAndMeasures_v2-3_15 1.1 Tuna RFMO Authorized Vessel Record Each tuna Regional Fisheries Management Organization (RFMO) develops vessel registration requirements and maintains a publicly available regional record of such tuna fishing vessels authorized to fish in the Convention Area of that RFMO …More
Gear Type: All Adopted: May 18, 2010
Amended: May 3, 2011
Amended: November 14, 2011
Amended: October 20, 2015Effective: May 3, 2011
A vessel may be included on the record of authorized fishing vessels in multiple RFMOs simultaneously.  Fishing by vessels subject to listing but not listed as authorized by an RFMO diminishes the effectiveness of conservation and management measures and the long-term sustainability of the resources being managed by increasing traceability and transparency at a global level. Processors, traders, importers, transporters, marketers and others involved in the seafood industry shall refrain from transactions in tuna caught by vessels that are not on the authorized vessel record of the RFMO governing the ocean area in which the tuna was caught, at the time of the fishing trip, so long as the vessel is subject to listing in the RFMO authorized vessel record.

ISSF_CommitmentsAndMeasures_v2-3_15 1.2   RFMO Participation ISSF recognizes that effective monitoring, control and surveillance of fishing activities within each RFMO is necessary for appropriate management. In some regions, however, vessels flagged to nations that are neither members nor cooperating non-members of the relevant RFMO are fishing for tunas, and thus are falling outside the purview of the RFMO management system. …More
Gear Type:All Adopted: October 26, 2011
Amended: October 20, 2015Effective: December 31, 2012
ISSF is committed to working to improve the performance of RFMOs in adopting, and member governments in complying with and enforcing, conservation and management measures and RFMO obligations. Processors, traders, importers, transporters, marketers and others involved in the seafood industry shall conduct transactions only with those vessels that are flagged to a member of the relevant RFMO (or cooperating non-member, if membership is not available under the RFMO Convention), or have applied with the RFMO for such status.

2) Traceability & Data Collection

ISSF_CommitmentsAndMeasures_v2-3_11 2.1   Product Traceability Adequate traceability records are necessary for enforcement and compliance with existing and future conservation measures, and the successful elimination of illegal, unregulated and unreported (IUU) fishing. …More

Amended: October 20, 2015
Effective: January 1, 2010
Processors, traders, importers, transporters, marketers and others involved in the seafood industry shall credibly trace tuna products, from capture to plate.  The traceability procedure will record the name, flag and UVI (subject to the provisions of Sections 4.1 and 4.2 below) of catcher and transshipping vessels, fish species, ocean of capture corresponding to tuna RFMO area, fishing trip dates, fishing gear employed, date the company took ownership of the fish and each species by weight.

ISSF_CommitmentsAndMeasures_v2-3_03 2.2   Quarterly Data Submission to RFMO ISSF recognizes that the tuna Regional Fisheries Management Organizations (RFMOs) are responsible for tuna conservation and management with the objective to maintain the populations at levels of abundance that can support the average maximum yield on a sustained basis.  …More

However, the scientific findings of the RFMO scientific bodies depend on the completeness and accuracy of the supporting data available to them.  ISSF is committed to support the RFMOs to ensure that their findings and the data underlying them are as accurate and complete as possible.

  1. Processors, traders, importers, transporters, marketers and others involved in the seafood industry shall submit the following data within their control to the appropriate RFMO scientific bodies:
    A) Round fish (includes gilled and gutted, and headed and gilled and gutted) unloading from
    Fishing Vessel
    i. Name of fishing vessel
    ii. Unique Vessel Identification Number (for example, IMO number) of fishing vessel
    iii. Gear type
    iv. Flag State of fishing vessel
    v. Start date for unloading to processor
    vi. End date for unloading to processor
    vii. RFMO area of subject catch
    viii. Fishing trip dates
    ix. Weight of catch (in metric tons, by commercial species/size categories compiled as
    specified in paragraph 2)
    x. Unloading port
    xi. Data source (unloading data, outturn report or immediate pre-processing)B) Round fish (includes gilled and gutted) unloading from Carrier Vessel (Transshipments)
    i. Name of carrier vessel
    ii. Unique Vessel Identification Number (for example, IMO number) of carrier vessel
    iii. Flag State of carrier vessel
    iv. Start date for unloading to processor
    v. End date for unloading to processor
    vi. Name(s) of catcher vessel(s)
    vii. Unique Vessel Identification Number(s) (for example, IMO number) of catcher vessel(s)
    viii. Flag state(s) of catcher vessel(s)
    ix. Date(s) of transfer of fish from catcher vessel(s) by vessel, and/or transfer from processor(s) to carrier vessel
    x. Locations of transfer(s) at sea [at sea coordinates/port name] by transfer
    xi. Fishing trip dates
    xii. Weight of catch (in metric tons, by commercial species/size categories by catcher vessel(s) compiled from immediate pre-processing data as specified in paragraph 2)
    xiii. Unloading port
    xiv. Data source (unloading data, outturn report or immediate pre-processing).
  1. Weight of catch (in metric tons) by commercial species/size categories should be compiled from immediate pre-processing data or from unloading data/outturn reports. The size classes should reflect commercial gradings used by the processor, with the following suggested minimum breakdowns:
    • Skipjack: <3 lb. (1.4 Kg); 3-4 lb. (1.4 -1.8 Kg); 4-7.5 lb.; >7.5 lb. (3.4 Kg). The category 3-4 lb. can be combined with the <3 lb. category if not generally measured by the processor.
    • Yellowfin and bigeye: <4 lb. (1.8 Kg); 4-7.5 lb. (1.8-3.4 Kg); 7.5-20 lb. (3.4-9 Kg); > 20 lb. (9 Kg). If used by the processor, the additional category 3-4 lb. (1.4-1.8 Kg) should be added.

Species separation for skipjack, yellowfin and bigeye should apply to all size breakdowns, unless practical considerations limit this separation in the smallest size classes (e.g. < 3 lb. or < 4 lb.), in which case the report should indicate the species mix.

  1. Submission of these data for each quarter shall be done by the last day of the following calendar quarter.  Submissions shall be done by electronic mail to the appropriate tRFMO scientific bodies whose contact information is available by clicking this link.

ISSF_CommitmentsAndMeasures_v2-3_11 2.3 Product Labeling by Species and Area of Capture Processors, traders, importers, transporters, marketers and others involved in the seafood industry shall on all product labeling or through a publicly available web-based traceability system by product, for all branded tuna products: …More

Effective: January 1, 2018
  1. Identify all species of tuna contained in the product; and
  2. Identify ocean of capture for the tuna contained in the product.
  3. For an ISSF Participating Company, this measure applies only to the branded products of that company.
  4. This measure will apply to all product labeling as of January 1, 2018.

3) Bycatch Mitigation

ISSF_CommitmentsAndMeasures_v3_13 3.1 Sharks “Shark finning” is the practice of retaining shark fins and discarding the remaining carcass while at sea. Shark finning contravenes the FAO Code of Conduct for Responsible Fisheries and its International Plan of Action for the Conservation and Management of Sharks, as well as the resolutions of a number of other international marine bodies, all of which call for minimizing waste and discards. …More
Shark finning has also contributed to major uncertainties about the total biomass and species composition of sharks caught. Tuna RFMOs restrict shark finning through a proviso that the weight of fins landed cannot exceed 5% of the total shark catch on board.  The fin-to-carcass ratio can vary considerably depending on the species, the dressing of the carcass, and on the different ways fins are cut, therefore creating difficulties in enforcement and accurate data collection.

ISSF_CommitmentsAndMeasures_v2-3_27 3.1(a)   Shark-Finning Policy In light of the difficulties in enforcement and accurate data collection, all ISSF Participating Companies shall establish and publish policies prohibiting shark finning. “Publish” for the purpose of this measure includes posting the policy on the company’s public website. …More
Gear Type:All Adopted: January 23, 2012
Amended: October 20, 2015
Effective: June 1, 2012
 In the event a Participating Company does not have a public website, the Participating Company shall make its policy otherwise available to the general public.

ISSF_CommitmentsAndMeasures_v2-3_23 3.1(b)   Prohibition of Transactions with Shark-Finning Vessels Processors, traders, importers, transporters, marketers and others involved in the seafood industry shall not conduct transactions with vessels that carry out shark finning. …More
Gear Type: All Adopted: January 23, 2012
Amended: October 20, 2015
Effective: September 1, 2012
For the purpose of determining if a vessel is conducting shark finning, processors, traders, importers, transporters and others involved in the seafood industry will rely upon the publicly available conclusions of investigations conducted by the RFMOs or national governments.After a period of 2 years from the date of the conclusion of the investigation, processors, traders, importers, transporters and others involved in the seafood industry can resume transactions with those vessels identified above, provided the vessels are not involved in further incidents.

ISSF_CommitmentsAndMeasures_v2-3_23 3.1(c)   Prohibition of Transactions with Companies without a Public Policy Prohibiting Shark Finning Processors, traders, importers, transporters, marketers and others involved in the seafood industry shall not conduct transactions with companies that do not have a public policy prohibiting shark finning. …More
Gear Type: All Adopted: January 23, 2012
Amended: October 20, 2015
Effective: September 1, 2012
For the purposes of this measure a policy is “public” if it is published on the company’s website or is otherwise available to the general public.

ISSF_CommitmentsAndMeasures_v3_23 3.2   Large-Scale Pelagic Driftnets Prohibition Large-scale pelagic driftnets are an unselective method of fishing that results in substantial catches of many non-target species. ISSF supports the Resolutions of the United Nations General Assembly 44/225, 45/197 and 46/215 concerning large-scale, high seas, pelagic driftnets and their impact on the living marine resources of the world’s oceans and seas. …More

  1. Processors, traders, importers, transporters, marketers and others involved in the seafood industry shall conduct transactions only with those purse seine vessels that retain all caught tuna (skipjack, yellowfin and bigeye), except those unfit for human consumption, or when in the final set of a trip, there is insufficient well space to accommodate all fish caught in that set.
  2. For purposes of this measure, “unfit for human consumption” means fish that :
    (i) is meshed or crushed in the purse seine net; or
    (ii)is damaged due to shark or whale depredation; or
    (iii) has died and spoiled in the net where a gear failure has prevented both the normal retrieval of the net and catch and efforts to release the fish alive.
  3. “Unfit for human consumption” does not include fish that: i. is considered undesirable in terms of size, marketability, or species composition; or ii. is spoiled or contaminated as the result of an act or omission of the crew of the fishing vessel.

ISSF_CommitmentsAndMeasures_v2-3_67 3.4  Skipper Best Practices ISSF’s goal in developing and presenting best practice information is to share the state of the art in responsible fishing operations, review the reporting requirements and other obligations to RFMOs, and inform purse seine vessel skippers and other interested parties about the related ISSF Conservation Measures for the management of tuna and its larger marine ecosystem. …More

ISSF_CommitmentsAndMeasures_v2-3_67 3.5 Transactions with Vessels that Use Only Non-entangling FADs Scientific studies have shown that FADs, when constructed with materials such as loose old netting, can entangle vulnerable species such as sharks. While some RFMOs have adopted a transition from traditional FADs to non-entangling FADs, others have not. ISSF is committed to support a transition to non-entangling FADs, globally. …More

  1. Processors, traders, importers, transporters, marketers and others involved in the seafood industry shall conduct transactions only with those purse seine vessels whose owners have a public policy regarding the use of only non-entangling FADs. The policy should refer to the ISSF Guide for Non-Entangling FADs and shall apply to all new FAD deployments, regardless of the type of vessel that deploys the FADs.
  2. For the purposes of this measure a policy is “public” if it is published on the company’s website or is otherwise available to the general public.
  3. The vessel owner must have a policy in place and published within six months of the adoption of this conservation measure that will be effective for new FAD deployments no later than 12 months after the vessel owner adopts its policy.
  4. For purposes of this measure, non-entangling FADs should meet the minimum specifications in the ISSF Guide for Non-Entangling FADs.  Vessel owners shall not deploy FADs that meet the description of “highest entanglement” contained in the ISSF Guide. practices.

4) Monitoring, Control and Surveillance

ISSF_CommitmentsAndMeasures_v2-3_51 4.1   Unique Vessel Identifiers – IMO The IHS-Fairplay administered International Maritime Organization numbering system (IMO number) provides a mechanism and registry for the unique identification and registration of vessels, which increases traceability and transparency at a global level. …More

ISSF_CommitmentsAndMeasures_v2-3_59 4.3(c) Observer Coverage – Grace Period for Electronic Monitoring Systems for Certain Large-Scale Purse Seine Vessels ISSF has defined for its Conservation Measures that large-scale purse seine vessels are those with at least 335 m3 fish hold volume. However, certain vessels who meet this definition are not considered large-scale in certain RFMOs and therefore are unable to obtain human observers for each fishing trip as a means to meet the requirements of ISSF Conservation Measure 4.3(a). Owners of large-scale purse seine vessels who fit in this category may seek to install an electronic monitoring system (if proven to be effective) in lieu of human observers.

. This exemption applies only to:

  • Vessels with carrying capacity ≤ 600mt; and
  • that fish only in the archipelagic waters of PNG; and
  • that are based in PNG and are associated with processing facilities in PNG.

The above vessels are allowed to transship on to carrier vessels that must go to a PNG port for either offloading or for transshipping in port under strict monitoring controls. These carrier vessels are not allowed to take the catch directly from PNG archipelagic waters to a foreign port.

Under PNG regulations, the vessels shall operate under the following conditions:

  1. Prior notification of transshipment is sent to the PNG National Fisheries Authority (information on the catcher and carrier vessels, date and time of transshipment, and quantities by species).
  2. One hundred percent observer coverage on the catcher vessel. The observer verifies the transshipment details.
  3. VMS coverage on both the carrier and catcher vessels.

A Freezer Vessel’s Fish Origin Declaration Form (with details about the date, place of transshipment and fish quantities) is filled by the carrier vessel for each transshipment, with the forms being submitted to the National Fisheries Authority. The form requires signatures/verification from officers in the catcher and carrier vessel as well as PNG port authorities.

 

5) Illegal, Unreported and Unregulated Fishing

ISSF_CommitmentsAndMeasures_v3_40 5.1   Illegal, Unreported and Unregulated (IUU) Fishing The tuna Regional Fisheries Management Organizations (RFMOs) maintain a list of all vessels determined to have carried out IUU fishing within their convention waters, and this list is available to the ISSF. …More

The IUU vessel lists maintained by RFMOs can include a range of vessels engaged in fishing activities, not just harvesting, such as transshipment activities. A vessel listed on the IUU list of one RFMO may fish in the convention waters of another RFMO and not be listed on the IUU list of this other RFMO.  IUU fishing diminishes the effectiveness of conservation and management measures and the long-term sustainability of the resources being managed.  IUU fishing denies the RFMOs important and valuable data and thereby undermines the effectiveness of their scientific programs.Processors, traders, importers, transporters, marketers and others involved in the seafood industry shall refrain from transactions in tuna caught by harvesting vessel(s) or transported by transshipment vessel(s) on the IUU Vessel List of any RFMO.

ISSF_CommitmentsAndMeasures_v3_43 5.2   Illegal, Unreported and Unregulated (IUU) Product Response Enforcement and compliance with existing and future conservation measures, and the successful elimination of illegal, unregulated and unreported (IUU) fishing requires the industry to maintain adequate traceability records. Since traceability data is acquired through Resolution 2.1, such data can be used to identify IUU product. …More
Gear Type:All Adopted: July 21, 2009
Amended: October 20, 2015
Effective: January 1, 2010
Processors, traders, importers, transporters, marketers and others involved in the seafood industry shall warrant that tuna products are in compliance with ISSF Conservation Measure 5.1 – IUU Fishing, and upon discovery of a violation of ISSF Conservation Measure 5.1, the company shall withdraw the product from the marketplace.

 

6) Capacity

Excessive fishing capacity contributes substantially to overfishing, the degradation of marine fisheries resources, the decline of food production potential, and significant economic waste. Purse seine vessels take more than sixty percent of the world’s tuna catch. Despite the general consensus among scientists, RFMOs, and many governments that excess fishing capacity exists in most of the tuna purse-seine fisheries, the fishing capacity of these fleets continues to grow.

The 2010 Bellagio Framework for Sustainable Tuna Fisheries concluded that, in a fully exploited fishery, coastal states’ rights to expand their participation in a tuna fishery must be accommodated by mechanisms for reducing the participation of others.

ISSF will continue to sponsor regional and global workshops on fleet capacity management, including mechanisms for capacity transfers.  In addition, ISSF has determined to assist international efforts to manage fishing capacity by tropical tuna purse seine fleets as follows:

ISSF_CommitmentsAndMeasures_v2-3_23 6.1   Transaction Ban for Large-Scale Purse-Seine Vessels not Actively Fishing for Tuna as of December 31, 2012 Processors, traders, importers, transporters, marketers and others involved in the seafood industry shall refrain from transactions in skipjack, bigeye and yellowfin tuna caught by large scale purse seine vessels that are not actively fishing for tuna as of December 31, 2012.  For the purposes of Section 6, large-scale purse seine vessels are those with at least 335 m3 fish hold volume. …More

1. Only vessels with all of the following information will be entered in the Record. Vessel information will be subject to verification by government agencies, RFMO secretariats, and other relevant agencies.

  • Name
  • Flag
  • IMO number
  • RFMO vessel record number(s)
  • National Registration Number
  • Radio Call Sign
  • Length overall (m)
  • Fish carrying capacity (metric tons)
  • Fish hold volume (m3)
  • Year and month built
  • Shipyard
  • If applicable: Previous name(s) and flag(s); date(s) changed.

2. ISSF will update the Record to include additional vessels in the following  circumstances:The addition of a large-scale purse seine vessel that was actively fishing for tuna on or before December 31, 2012 but cannot have ceased fishing operations prior to January 1, 2010, that was not included in the Record initially.

  1. The addition of a large-scale purse seine vessel that was under contract for construction on or before December 31, 2012 with construction completed by June 30, 2015. “Under contract for construction” means that there is evidence that a valid contractual obligation was in place for the construction of the vessel. “Construction completed” means that the vessel has been delivered and is ready to commence fishing operations.
  2. A change in the name, flag, or registration number of a vessel already on the Record.
  3. The addition of a new large-scale purse seine vessel that is built as a replacement for a vessel already on the Record that has sunk, has been scrapped or otherwise permanently transferred out of the tropical tuna fishery.
  4. The addition of the new vessel will only be permitted only if: the new vessel replaces a vessel on the ISSF Record and its fish hold volume is less than or equal to that of the older vessel that was on the ISSF Record; or the aggregated replaced capacity of more than one vessel already on the ISSF Record must be at least 1.2 times the new capacity (aggregated replaced capacity/1.2 = permitted new capacity). The request for the addition of a new vessel shall come either from the owner of the older vessel, or from a new owner designated by the owner of the older vessel.
