Non‑entangling biodegradable fish aggregating devices
Fish aggregating devices that, in addition to having no risk of entanglement, are constructed using only natural and/or biodegradable materials (e.g., bamboo, sisal, jute, palm leaves, coconut fiber, cotton) to further reduce the environmental impact of FADs on the oceans.
