What’s Up With Derelict Crab Pots?

1 Comment

Derelict crab pots have recently been popping up in the media, and you may be wondering, “what’s up with all these crab pots?” Well, derelict pots are numerous in heavily fished waters and can create all sorts of problems for both the habitat where they are found and the local economy. Recently, there have been many efforts that are taking advantage of closed crabbing seasons to remove some of these derelict pots and learn more about them.

Derelict crab pots are a big problem for many coastal areas. These traps that have been lost, abandoned, or discarded into the marine environment end up there in a variety of ways. Oftentimes, crab pots are lost after bad weather, being improperly set up, or from lines being inadvertently cut from passing vessels. Once a crab pot becomes derelict, it can start to wreak some havoc. Not only can derelict pots become navigational hazards or damage sensitive coastal habitats, but they can also result in a phenomenon called “ghost fishing.” Ghost fishing occurs when derelict fishing gear continues to capture marine life, a catch that ends up going to waste and often results in the mortality of whatever organism was captured. This often also translates to economic loss, a connection that was recently explored in a newly published study by the Virginia Institute of Marine Science (VIMS).

This VIMS study details how fishermen can suffer economic losses associated with derelict crab pots. As derelict pots remain in local waters, they continue to capture marine organisms, including harvestable crabs. These crabs go to waste and, having already been captured by a derelict pot, can no longer be caught by professional crabbers who rely on such catches for their livelihood. By removing derelict pots, these financial losses can be avoided. For more information on this study, check out this blog post.

To avoid these financial losses and other negative impacts associated with derelict crab pots, there are many efforts underway to remove them. Three new projects in New Jersey aim to both remove derelict pots and educate the public about how to avoid losing pots in the first place. Check out this blog post to learn more about these projects. In Louisiana, derelict crab pots are such a big issue in the New Orleans area that the Louisiana Department of Wildlife and Fisheries is hosting two “Derelict Crab Trap Rodeos.” These are day long events during which volunteers work to remove derelict crab traps from local waters. The first event is this coming Saturday, February 13th, so if you’re in the area, stop by and help remove some derelict pots! But don’t worry if you can’t make this one, you’ll get a second chance at the next event on February 20th. For more information on this project, check out our website.

Our mission is to investigate and solve the problems that stem from marine debris, in order to protect and conserve our nation's marine environment, natural resources, industries, economy, and people.

One thought on “What’s Up With Derelict Crab Pots?

  1. There is a paper in Marine Pollution Bulletin by Justine Martens and Brittany Huntington – ” Creating a GIS- model of marine debris ” hot spots” to improve efficiency of a lobster trap debris removal program”. They analyzed 5 years worth of trap removal data in Biscayne National Park here in S.FL. Along with generating a hot spot map, they indicated that the efforts of using contractors for removal did not reduce the incredible amount still left in situ. Suggesting that the amount of effort needed to be removed this debris is tremendous. Its kind of sad thinking out of all the current efforts there are, there will always be more dumped on top of it making it nearly impossible to clean it up (unless something is done about it at a management level). Either way its good read just like this one to get the conversation started. Thanks for the post!
