REPORT: Evaluating the Lifetime of Biodegradable Ropes

ISSF continues its efforts to help tuna fishers accelerate their use of fish aggregating device (FAD) designs with the least possible impact on the marine ecosystem. An example is collaborative work to identify materials of natural origin to reduce the impact caused by beaching and sinking of FADs.

A new report reviews the results of a project to test the lifetime and robustness of biodegradable ropes for use on FADs. Tests were conducted in a controlled environment in the Maldivian waters; research questions for the experiment included: 

  • Which is the best definition for a biodegradable material to be used at FADs?
  • What are the features needed for a given biodegradable material to be used successfully at FADs?
  • What are the most appropriate biodegradable materials and ropes among those with potential to be used at FADs?
  • What is the lifetime of biodegradable materials when in the open ocean?
  • What is the lifetime of biodegradable materials when they arrive to the coast and/or gets stranded?

WATCH: Biodegradable FAD Workshops  

A video offers an overview of recent workshops in the Western and Central Pacific Ocean that are part of an ongoing work with fishers, scientists and industry to find the best non-entangling designs and natural materials for FADs that can biodegrade.

BLOG: 2019 Recap

“True, our work with the world’s regional fishing management organizations (RFMOs) generated some notable accomplishments. Equally true: the pursuit of other victories just consumed a ton of patience. In that spirit, I’d like to recap the year’s RFMO activity in sustainably conserving and managing the world’s tuna resources — ISSF’s core mission.”

About the International Seafood Sustainability Foundation (ISSF)

The International Seafood Sustainability Foundation (ISSF) is a global coalition of scientists, the tuna industry and World Wildlife Fund (WWF) — the world’s leading conservation organization — promoting science-based initiatives for the long-term conservation and sustainable use of tuna stocks, reducing bycatch and promoting ecosystem health. Helping global tuna fisheries meet sustainability criteria to achieve the Marine Stewardship Council certification standard — without conditions — is ISSF's ultimate objective. In 2019, ISSF celebrated a “Decade of Discovery” as the organization completed its tenth year of scientific research, advocacy and industry engagement.
