Humpback Whale Entanglement in Alaska 1990–2011 (poster)
Entanglements are a significant source of anthropogenic injury and mortality for humpback whales in Alaska. Most events reported to NOAA Fisheries have occurred in Southeast Alaska, and the majority of reported gear involves crab, shrimp, and unidentified pot gear, as well as gillnet and other unidentified nets. These types of entanglement incidents can be life-threatening to humpback whales by inhibiting their ability to move, breathe, and forage.
