Within this project, multiple supply chains engaged in the Handline and Pole and Line fishery in Indonesia were categorized into a set of generic supply chain types. This allowed us to audit a wide set of supply chain types and create a generic improvement approach for each type. We shared improvement approaches with an entire group of industries engaged in the industry association AP2HI, at present over 20 companies and allow them to independently work towards the Marine Stewardship Council (MSC) Chain of Custody (CoC) Standard as well as increasing international traceability requirements.
