Summary

This study investigates the mechanical performance of biodegradable fishing nets made from poly(butylene succinate-co-adipate-co-terephthalate) (PBSAT) as compared to conventional polyamide 6 (PA6) nets, in order to address ghost fishing and microplastic pollution by developing fishing gear that degrades in marine environments without compromising mechanical efficiency. ​Results show that PBSAT nets are weaker than PA6 nets in each component- monofilament, knots, and net. PBSAT nets biodegrade more easily, but do not match the current mechanical properties for commercial fishing.
