Development and Evaluation of Reduced Breaking Strength Rope to Reduce Large Whale Entanglement Severity

Bycatch species:

Large Cetaceans (maximum length > 7.5 meters)

Reduction technique:

Weak links/ropes

Fishing Gear:

Traps

Drag from fishing gear entangling North Atlantic right whales

Study Type:

Summary study

Location:

US Atlantic

Target catch:

N/A

Effect on bycatch species:

Information suggests that on average entanglements increase drag and propulsive power by 1.47 fold. Reducing trailing line length by 75% can reduce parasitic gear drag by 85%.
