derelict fishing gear

Derelict fishing nets are a big marine debris problem. These nets can entangle wildlife, create major hazards to navigation, and can damage sensitive and important habitats. Unfortunately, they can also be difficult to address as they often have few identifying characteristics. This makes determining their source challenging and makes derelict nets difficult to track.

Derelict fishing nets are a particularly large problem in the Hawaiian archipelago, due to Hawaii’s geographic location in the North Pacific Gyre and Convergence Zone and the large amounts of fishing that occurs domestically and internationally in the Pacific. The North and East Coast shorelines of each Hawaiian Island are the most impacted, due to the northeast trade winds that blow this debris ashore.

The Chesapeake Bay blue crab fishery accounts for 50% of the United States blue crab harvest, and is worth about $80 million annually. It’s estimated that about 600,000 crab traps (also called “pots”) are actively fished on an annual basis in the Bay. Some crab pots become lost (derelict) when the pot’s buoy line becomes detached or cut, either by vessel propellers, faulty lines, or vandalism. Strong storms can also move pots from their original deployment location, making them difficult to relocate. In addition, pots may be abandoned, as has been observed at high rates in some regions of the Bay. Once lost, derelict pots can damage sensitive habitats and continue to capture blue crabs and other animals, often resulting in their death. 

Marine debris is a pervasive problem and unfortunately, our golden state on the west coast is not immune. However, the NOAA Marine Debris Program (MDP) is supporting some innovative projects that are actively addressing this problem. To give you a cool example, California is the site of a nifty marine debris removal project that started last summer.

Led by the SeaDoc Society at the University of California, Davis and working with area fishermen, this project in Northern and Central California is working to fight a big debris problem: derelict crab traps. Derelict traps can cause all kinds of problems for marine life, recreational boaters, and for fishermen. Apart from losing expensive traps, the fishery suffers as derelict traps continue to capture crabs that could otherwise be caught by an active fisherman (a concept known as ghost fishing). To address this problem, commercial fishermen are going out during the closed crabbing season to recover lost pots.

Over the years of the NOAA Marine Debris Program, there have been many efforts around the country to rid our waters and shores of marine debris. As part of our ten-year anniversary celebration, let’s take a look back at one of those efforts in our Southeast region.

Derelict fishing gear can cause lots of problems, including damaging important and sensitive habitats, ghost fishing, and posing hazards to navigation. Unfortunately, derelict commercial lobster and crab traps are a prominent type of marine debris in the Florida Keys.

Research is an important part of our fight against marine debris, as it allows us to learn more about the topic and be better able to target and address it in the future. Thanks to a new study by our very own Chief Scientist, Amy Uhrin, we now know a little more about derelict lobster traps and how they impact habitat in the Florida Keys. Read all about it and get the link to the scientific paper in this NOAA Response and Restoration blog post.

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!

On Friday, February 26^th, the NOAA Marine Debris Program and its partners held an event in Waretown, New Jersey, to highlight an exciting derelict crab pot removal effort in Barnegat Bay. The event highlighted a project, led by the Conserve Wildlife Foundation of New Jersey and supported by a NOAA Marine Debris Program Community-based Marine Debris Removal grant, which is working to identify, retrieve, and inventory over 1,000 derelict crab pots from Barnegat Bay, N.J.

Covanta partnered with the Conserve Wildlife Foundation of New Jersey to provide two bins for collecting the retrieved derelict gear, to then haul and dispose of at their waste-to-energy facility. 

The 2015 Fishing for Energy Partnership grant awards support projects to help commercial and recreational fishermen and boaters reduce the amount of fishing gear lost in the marine environment.
