entanglement

Hawaiian monk seals face many threats caused by humans, including food limitation and habitat loss. However, one of their most significant threats is marine debris. Hawaiian monk seals are observed stuck in nets and fishing gear more than almost any other pinniped (seal, sea lion, or walrus) species. Seals can be entangled in all types of derelict fishing gear, including nets, lines, and hooks from non-commercial and commercial fishing. Entanglement can make it difficult for seals to breathe, hunt for food, and escape from predators, potentially leading to injury or death. Entanglement is seen more frequently in Papahānaumokuākea Marine National Monument.

When we think about marine debris, we often picture the turtles, fish, and marine mammals that are impacted by plastics, fishing gear, and other marine debris. But what about wildlife that spends its time above water? World Migratory Bird Day (WMBD) is coming up this Saturday, May 11, and we are working with Environment for the Americas to raise awareness on the importance of migratory bird species, and the ways we can protect birds from the threat of plastic pollution and marine debris.

Marine debris is one of the most widespread pollution problems facing our ocean and waterways today. This issue of solid, man-made materials in the ocean or Great Lakes is a global one that leaves no part of the world untouched by debris and its impacts. These negative effects impact people on a daily basis, from economic losses to potential health hazards, but can impact marine animals most severely. Animals are impacted by marine debris in a variety of ways, check them out here and what we can do to help.

The NOAA Marine Debris Program is celebrating our 10-year anniversary throughout 2016. As part of this celebration, we’d like to take the time to look back on some of our past work. Check out this entangled sea turtle that was found back in 2006 and happily released back into Hawaiian waters, free of marine debris.

Marine debris can impact our ocean in many ways, one of which is wildlife entanglement. On this trip, a sea turtle was found entangled in a derelict fishing net.

As members of the NOAA marine debris removal effort in the Northwestern Hawaiian Islands were about to start the process of removing a large derelict net ensnared on some coral, they found a surprise— a poor entangled sea turtle! Each year, NOAA supports this effort to remove marine debris from the Papahānaumokuākea Marine National Monument, which resulted in over 14.5 metric tons of debris collected last year alone!

A plastic bag may look flimsy, but in a fight against a sea turtle, it often wins. Unfortunately, the marine debris that we find floating in our oceans and waterways all too often impacts marine life.

There are many ways that marine debris can impact marine animals. For instance, the accidental ingestion of debris is a big problem! Animals may unintentionally eat debris along with their meal, or intentionally ingest trash due to its resemblance to real food.
