We’re working with fishers, fellow scientists, and the seafood industry to find the best bio-FAD natural materials and non-entangling designs to meet fisher needs while protecting marine life. ISSF has partnered with FAO GEF Common Oceans Tuna Project on bio-FAD research projects.
The term “biodegradable” is applied to a material or substance that is subject to a chemical process during which microorganisms in the environment convert materials into natural substances — such as water, carbon dioxide, and decomposed organic matter — that are non-toxic for the marine environment.
The time required for biodegradation of different materials varies.
Our outreach to fishers includes hands-on workshops at major ports with ISSF scientists, conceptualizing bio-FAD designs and discussing FAD management challenges and solutions. We have created videos highlighting some of these workshops and published reports about them. We also offer educational videos, guidebooks, posters, and other resources for skippers.
With input from workshop participants, our scientists also have identified modifications to FAD structures and size that may further reduce their ecosystem impacts.
Physical oceanographers also have collaborated with us — on a new, smaller type of bio-FAD, the jelly-FAD, that we are piloting.
New bio-FAD designs are scientifically tested and validated before they can be recommended to tuna fleets for adoption.
ISSF is conducting scientific trials of bio-FAD prototypes under controlled as well as real fishing conditions. We have deployed bio-FADs around the world — in cooperation with commercial fishing fleets and partner organizations — to evaluate the performance of different FAD structures and organic materials.
Fleets in three tropical oceans are now testing bio-FAD designs and collecting data from these experiments for scientific analysis.
ISSF Scientist Dr. Gala Moreno blogs about her research on “jelly-FADs,” a type of biodegradable FAD co-designed with physical oceanographers.
Jelly-FADs are made of organic materials and drift slowly, like jellyfish. Since ocean currents are less likely to carry them too far afield, they may have less impact on the marine environment if they are lost or abandoned by fishers.
