Biodegradable Nets: The Next Wave of Sustainable Fishing
Summary
This review examined biodegradable fishing nets made from materials like PLA and PBS as alternatives to conventional synthetic nets that contribute to ghost fishing and microplastic pollution when abandoned. The authors found that biodegradable nets match the functional performance of synthetic ones while degrading in marine environments, though deployment scale and cost-effectiveness remain barriers to adoption.
Biodegradable fishing nets are emerging as a promising solution to one of the ocean’s most persistent threats ghost nets. Across the world, abandoned synthetic nets continue to harm marine ecosystems by trapping wildlife, damaging coral reefs, and contributing to microplastic pollution. Biodegradable nets, made from eco-friendly materials such as PLA and PBS, offer the same functionality as traditional nets during fishing but naturally break down when lost or discarded. This reduces long-term environmental harm and interrupts the destructive cycle of ghost fishing. Field studies show that biodegradable nets can achieve comparable catch performance while providing added benefits for fishermen, including market recognition and potential government incentives. Although challenges remain, particularly in cost and durability optimization, biodegradable nets represent a crucial step toward sustainable fisheries and healthier oceans.
