Title: Market acceptance based on compliance with European Union regulations: Traceability study for the tuna and tuna-like species processing industry in Indonesia.

This study aimed to suggest improvements in the traceability practices for Indonesian tuna and tuna-like species products to comply with regulation (EU) 2023/2842 (the amendment of Fisheries Control Regulation) and to emphasise the transformation of paper-based catch certificates to a complete digital system by mapping the current traceability. The impact of regulation (EU) 2023/2842 on non-EU countries was reviewed in this study. An Icelandic traceability scheme based on the General Food Law Regulation (EC) No. 178/2002 was observed and compared to the Indonesian scheme to identify the gap. The results show that the current supply chain of tuna and tuna-like species in Indonesia meets the legal requirements for traceability in the EU, referring to Council Regulation (EC) No 1005/2008. It has also met the standards of food safety in the EU by implementing Council Regulation (EEC) No. 315/93 and the hygienic requirements related to sanitary and phytosanitary (SPS) conditions and microbiological criteria of the final product. The Icelandic traceability system shows that the vertical integration of information technology managed by the Directorate of Fisheries facilitates the effective transfer of fish traceability information from vessels to processing plants. This study compares the traceability systems in Indonesia and Iceland and suggests improvements for the current situation in Indonesia in transferring information on fish batches as raw materials from a paper-based (delivery note/purchasing note) system to an electronic system in the processing plant to address the amendment of the Fisheries Control Regulation. This study also suggests that adopting a Global Returnable Asset Identifier (GRAI) for the insulated box or the built-in hatch in a boat for one-day tuna fishing will facilitate tracking and make transferring information from GRAI to Global Trade Item Number (GTIN) more accessible.
