Derelict Crab Trap Removal

Derelict crab traps are traps that have been lost or abandoned due to a number of reasons:

  • Separated from their buoys by tides, currents, storms, or passing boats
  • Caught in and displaced by shrimp gear
  • Vandalism
  • Improper disposal of old, unfishable traps
  • Poor assembly or maintenance of lines and floats
  • Abandoned by fishermen leaving the fishery.

Since most crab traps are made of vinyl coated wire mesh, it can take years for a derelict crab trap to degrade. In the meantime, these traps can “ghost fish”, which means they continue to capture blue crabs and other species. They can also create a navigational hazard for boats and become entangled in other fishing gear like shrimp nets.

The removal of derelict crab traps is essential for reducing mortality of blue crabs and other species due to ghost fishing. This also ensures safe navigation, reduces conflicts with other fisheries and user groups, and improves the aesthetics of state waterways.

 

Derelict Crab Trap Removal Program

The Louisiana Wildlife and Fisheries Commission established a Derelict Crab Trap Removal Program in 2004 to remove derelict crab traps from state-owned lake and river beds and other water bottoms and reduce their potential impacts. The program also collects data on the number and types of animals found in recovered traps. This program is funded in part by the sale of Louisiana crab fishing licenses and is run by LDWF, Louisiana Sea Grant, and volunteers.

Under this program, the Commission may close areas to crab traps during the following times every year:

  • A period not to exceed 16 consecutive days between February 1 and March 31
  • A period not to exceed 14 consecutive days, which includes the opening day of the spring inshore shrimp season
  • When crab harvest is closed for biological or technical reasons, the Commission may prohibit crab traps for the duration of the closure.

Any crab trap found in these areas of the state when the Commission has prohibited their use shall be considered abandoned and may be removed by persons authorized by the Commission.
